The dnl default (if it is not specified or empty) is 'no-libtool'. dnl INTLSYMBOL should be 'external' for packages with no intl directory, dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory. dnl If INTLSYMBOL is 'use-libtool', then a libtool library dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static, dnl depending on --{enable,disable}-{shared,static} and on the presence of dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library dnl $(top_builddir)/intl/libintl.a will be created. dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext dnl implementations (in libc or libintl) without the ngettext() function dnl will be ignored. If NEEDSYMBOL is specified and is dnl 'need-formatstring-macros', then GNU gettext implementations that don't dnl support the ISO C 99 formatstring macros will be ignored. dnl INTLDIR is used to find the intl libraries. If empty, dnl the value `$(top_builddir)/intl/' is used. dnl dnl The result of the configuration is one of three cases: dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled dnl and used. dnl Catalog format: GNU --> install in $(datadir) dnl Catalog extension: .mo after installation, .gmo in source tree dnl 2) GNU gettext has been found in the system's C library. dnl Catalog format: GNU --> install in $(datadir) dnl Catalog extension: .mo after installation, .gmo in source tree dnl 3) No internationalization, always use English msgid. dnl Catalog format: none dnl Catalog extension: none dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur. dnl The use of .gmo is historical (it was needed to avoid overwriting the dnl GNU format catalogs when building on a platform with an X/Open gettext), dnl but we keep it in order not to force irrelevant filename changes on the dnl maintainers. dnl AC_DEFUN([AM_GNU_GETTEXT], [ dnl Argument checking. ifelse([$1], [], , [ifelse([$1], [external], , [ifelse([$1], [no-libtool], , [ifelse([$1], [use-libtool], , [errprint([ERROR: invalid first argument to AM_GNU_GETTEXT ])])])])]) ifelse([$2], [], , [ifelse([$2], [need-ngettext], , [ifelse([$2], [need-formatstring-macros], , [errprint([ERROR: invalid second argument to AM_GNU_GETTEXT ])])])]) define(gt_included_intl, ifelse([$1], [external], [no], [yes])) define(gt_libtool_suffix_prefix, ifelse([$1], [use-libtool], [l], [])) AC_REQUIRE([AM_PO_SUBDIRS])dnl ifelse(gt_included_intl, yes, [ AC_REQUIRE([AM_INTL_SUBDIR])dnl ]) dnl Prerequisites of AC_LIB_LINKFLAGS_BODY.

Los respectivos muestreos de frecuencia de color no varían lo que hace que el adjunto soporte pruebas estadísticas del primer orden. Sus características incluyen el compactado y el encriptado de los datos adjuntos, y revisión automática de integridad usando un checksum. Se reconocen los formatos de archivo JPEG, BMP, WAV y AU para usar como archivos de portada. No existen restricciones en el formato de los datos ocultos. Steghide aplica un enfoque estenográfico 'gráfico-teórico'(e.i.'graph-theoretic'). No necesitamos saber nada sobre teorías gráficas para usar steghide. Tranquilamente podemos saltearnos el resto del párrafo si no nos interesan los detalles técnicos. El algoritmo de adjunto funciona así a groso modo: Primero, se compacta y encripta la información secreta. Luego se crea una secuencia de posiciones de pixels en el archivo portada basado en un generador pseudo-aleatorio de números inicializado con un salvoconducto (los datos secretos se adjuntarán en los pixels de estas posiciones). En estas posiciones,se excluyen los que no necesitan cambiarse (porque ya tienen el valor correcto, por casualidad). Luego, un algoritmo gráfico-teórico de concordancia halla pares de posiciones de forma que al intercambiar sus valores dejemos adjunta la parte correspondiente a los datos secretos. Cuando el algoritmo encuentra el último par, se realiza el intercambio. Los pixels de las posiciones sobrantes(las posiciones que no conforman dichos pares) también se modifican para llevar los datos adjuntos(pero esto se hace sobreescribiéndolos, no intercambiándolos con otros pixels). El hecho de que (en su mayor parte) se adjunta intercambiando valores de píxels implica que las estadísticas de primer orden (x.e. las veces que se usa un color en la imagen) no se alteran. En los archivos de audio se usa el mismo algoritmo, aunque se usan muestras de audio en lugar de pixels. El algoritmo de encriptado por omisión es el Rijndael con clave de 128 bits de tamaño (que es EAE (e.i.AES)\- Encriptado Avanzado Estandar) en la modalidad de encadenado de bloques de cifras. Si esta combinación, por el motivo que sea, no nos da confianza, tenemos la libertad de elegir otra combinación de algoritmo/tipo (el comando \fBencinfo\fP nos muestra información sobre todas las combinaciones de algoritmos y tipos). El checksum se calcula usando el algoritmo CRC32. .SH COMANDOS En esta sección se listan los comandos de steghide. El primer argumento deberá ser siempre uno de los siguientes comandos. Podemos agregarle argumentos adicionales a los comandos \fBembed\fP, \fBextract\fP y \fBinfo\fP. Los demás comandos no llevan ningún argumento. .TP .B "embed, --embed" Adjuntar datos secretos en un archivo portada creando un archivo stego. .TP .B "extract, --extract" Extraer datos secretos de un archivo stego. .TP .B "info, --info" Mostrar información sobre un archivo portada o uno stego. .TP .B "encinfo, --encinfo" Mostrar una lista de algoritmos y tipos que pueden usarse. No necesita argumentos. .TP .B "version, --version" Mostrar una breve información sobre la version. No necesita argumentos. .TP .B "license, --license" Mostrar la licencia de steghide. No necesita argumentos. .TP .B "help, --help" Mostrar una pantalla de ayuda. No necesita argumentos. .SH ADJUNTO Deberíamos usar el comando \fBembed\fP cuando queremos adjuntar datos secretos en un archivo de portada. Con el comando \fBembed\fP pueden usarse los siguientes argumentos: .TP .B "-ef, --embedfile \fInomArchivo\fP" Declarar el archivo a adjuntar(el archivo que tiene el mensaje secreto). Notar que steghide adjunta el nombre original del archivo en el archivo stego. Cuando extraemos los datos (ver más abajo) tiende, por omisión, a grabar el archivo adjunto en el directorio actual y con su nombre de archivo original. Si se omite este argumento o \fInomArchivo\fP es \fB-\fP, steghide leerá los datos secretos desde la entrada estandar. .TP .B "-cf, --coverfile \fInomArchivo\fP" Declarar el nombre del archivo de portada que usaremos para adjuntar los datos. El archivo de portada debe tener uno de los siguientes formatos: AU, BMP, JPEG o WAV. El formato del archivo se detecta automáticamente basándose en la información de su cabecera (no importa su extensión). Si omitimos este argumento o \fInomArchivo\fP es \fB-\fP, steghide leerá el archivo de portada desde la entrada estandar. .TP .B "-sf, --stegofile \fInomArchivo\fP" Declarar el nombre del archivo stego a crearse. Si omitimos este argumento cuando llamamos a steghide con el comando \fBembed\fP, las modificaciones para adjuntar los datos secretos se harán directamente en el archivo portada sin grabarlo con un nombre nuevo. .TP .B "-e, --encryption \fIalgo\fP [ \fItipo\fP ] | \fItipo\fP [ \fIalgo\fP ]" Declarar parámetros de encriptado. A esta opción debe seguirle una o dos cadenas que definan un algoritmo de encriptado y/o un tipo. Los nombres de todos los algoritmos y tipos posibles pueden obtenerse con el comando \fBencinfo\fP. El encriptado por omisión es \fBrijndael-128\fP (EAE) de tipo \fBcbc\fP. Si no quisiéramos usar ningún encriptado, usaríamos \fB-e none\fP. .TP .B "-z, --compress \fInivel\fP" Declarar el nivel de compactado. El nivel de compactado es de 1...9. Donde 1 representa el más rápido y 9 representa el mejor compactado. .TP .B "-Z, --dontcompress" No compactar la información secreta antes de adjuntarla. .TP .B "-K, --nochecksum" No adjuntar el checksum CRC32. Podemos usar esto si los datos secretos ya tienen algún tipo de checksum o si no queremos adjuntar esos 32 bits extras para hacer el checksum. .TP .B "-N, --dontembedname" No adjuntar el nombre del archivo secreto. Si se usa esta opinión, el extractor necesitará declarar un nombre de archivo para decirle a steghide en donde escribiremos los datos adjuntos. .SH EXTRACCIÓN Si hemos recibido un archivo que tiene un mensaje adjunto con steghide, usaremos el comando \fBextract\fP para extraerlo. Pueden usarse los siguientes argumentos con este comando. .TP .B "-sf, --stegofile \fInomArchivo\fP" Declara el archivo stego (el archivo que contiene los datos adjuntos). Si se omite este argumento o \fInomArchivo\fP es \fB-\fP, steghide leerá un archivo stego desde la entrada estandar. .TP .B "-xf, --extractfile \fInomArchivo\fP" Crear un archivo con nombre \fInomArchivo\fP y grabar los datos adjuntos del archivo stego en él. Esta opción sobreescribe el nombre del archivo adjuntado en el archivo stego. Si se omite este argumento, los datos adjuntos se grabarán en el directorio actual con su nombre original. .SH OBTENIENDO INFORMACIÓN DE UN ARCHIVO DE PORTADA/STEGO Podemos usar el comando \fBinfo\fP para obtener información sobre un archivo portada o stego (por ejemplo su tamaño). Podríamos necesitar usarlo cuando recibimos un archivo y no estamos seguros de que contenga un mensaje adjunto o si pensamos usar cierto archivo como archivo portada y queremos averiguar su tamaño. El comando de linea \fBsteghide info\fP \fI\fP devolverá información sobre \fI\fP y luego nos preguntará si queremos ver la información sobre los datos adjuntos en ese archivo. Si respondemos 'yes' tendremos que escribir el salvoconducto que se usó para adjuntar los datos en ese archivo. También podemos agregarle el argumento \fB-p, --passphrase\fP (ver abajo) al comando \fBinfo\fP para que steghide intente obtener automáticamente la información adjunta usando el salvoconducto declarado. .SH OPCIONES COMUNES Las siguientes opciones pueden usarse en todos los comandos (donde tenga algún sentido). .TP .B "-p, --passphrase" Usar como salvoconducto, la cadena que le sigue a este argumento. Si nuestro salvoconducto contiene espacios en blanco, habremos de encerrar todo entre comillas, por ejemplo: \fB-p "un salvoconducto muy extenso"\fP. .TP .B "-v, --verbose" Mostrar información muy detallada sobre el estado del proceso de adjuntado o del de extracción. .TP .B "-q, --quiet" Evitar mensajes informativos. .TP .B "-f, --force" Siempre sobreescribir los archivos existentes. .SH OPCIONES DE NOMBRE DE ARCHIVO Todos los argumentos de nombre de archivo (\fB-cf\fP, \fB-ef\fP, \fB-sf\fP, \fB-xf\fP) también aceptan \fB-\fP como nombre de archivo lo que hará que steghide use la entrada o salida estandar (lo que tenga sentido). Omitiendo el argumento correspondiente a su nombre de archivo es lo mismo que escribir \fB-\fP excepto en dos casos: Si se omite \fB-sf\fP en el comando embed, se harán las modificaciones directamente sobre el archivo de cubierta. Si se omite \fB-xf\fP para la extracción, los datos adjuntos se grabarán con el nombre de archivo que figura en el archivo stego. Así que cuando queramos asegurarnos de que se use la entrada/salida estandar, usaremos \fB-\fP como nombre de archivo. .SH EJEMPLOS Básicamente se usa así: $ steghide embed -cf imagen.jpg -ef secreto.txt Ingrese salvoconducto: Re-ingrese salvoconducto: adjuntando "secreto.txt" en "imagen.jpg"... hecho Este comando adjuntará el archivo secreto.txt en el archivo de portada imagen.jpg. Una vez adjuntado nuestro archivo de datos secretos como vimos antes se puede enviar el archivo imagen.jpg a la persona que debería recibir el mensaje secreto. El receptor debe usar steghide de la siguiente manera: $ steghide extract -sf imagen.jpg Ingrese salvoconducto: los datos extraídos se grabaron en "secreto.txt". Si el salvoconducto declarado es el correcto, el contenido del archivo original secreto.txt se extraerá del archivo stego imagen.jpg y se grabará en el directorio actual. Si hemos recibido un archivo que contiene datos adjuntos y quisiéramos tener más información sobre el mismo antes de extraerlo, usaremos el comando info: $ steghide info archivo_recibido.wav "archivo_recibido.wav": formato: wave audio, PCM encoding capacidad: 3.5 KB ¿ Intento extraer información sobre los datos adjuntos? (y/n) y Ingrese salvoconducto: archivo adjunto "secreto.txt": tamaño: 1.6 KB encriptado: rijndael-128, cbc comprimido: si Luego de emitir algunos datos generales sobre el archivo stego (formato, capacidad) se nos preguntará si queremos que steghide obtenga información sobre los datos adjuntos. Si respondemos con yes tendremos que declarar un salvoconducto. Steghide entonces intentará extraer los datos adjuntos con ese salvoconducto y - si tiene 'éxito - emitirá un informe sobre el mismo. .SH VALOR DE RESPUESTA Steghide devuelve 0 si tiene éxito 1 si ocurre un fallo y debe terminar antes de terminar la operación solicitada. Las advertencias no tienen efecto en los valores de respuesta. .SH AUTOR Stefan Hetzl .SH Traducción al castellano versión 1 - Alberto Adrián Schiano steghide-0.5.1/doc/steghide.10000644000076400001440000002426407743177043011441 .\" steghide 0.5.1 man page .TH steghide 1 "13 Oct 2003" .SH NAME steghide \- a steganography program .SH SYNOPSIS .B steghide .I command [ .I arguments ] .SH DESCRIPTION .B Steghide is a steganography program that is able to hide data in various kinds of image- and audio-files. The color- respectivly sample-frequencies are not changed thus making the embedding resistant against first-order statistical tests. Features include the compression of the embedded data, encryption of the embedded data and automatic integrity checking using a checksum. The JPEG, BMP, WAV and AU file formats are supported for use as cover file. There are no restrictions on the format of the secret data. Steghide uses a graph-theoretic approach to steganography. You do not need to know anything about graph theory to use steghide and you can safely skip the rest of this paragraph if you are not interested in the technical details. The embedding algorithm roughly works as follows: At first, the secret data is compressed and encrypted. Then a sequence of postions of pixels in the cover file is created based on a pseudo-random number generator initialized with the passphrase (the secret data will be embedded in the pixels at these positions). Of these positions those that do not need to be changed (because they already contain the correct value by chance) are sorted out. Then a graph-theoretic matching algorithm finds pairs of positions such that exchanging their values has the effect of embedding the corresponding part of the secret data. If the algorithm cannot find any more such pairs all exchanges are actually performed. The pixels at the remaining positions (the positions that are not part of such a pair) are also modified to contain the embedded data (but this is done by overwriting them, not by exchanging them with other pixels). The fact that (most of) the embedding is done by exchanging pixel values implies that the first-order statistics (i.e. the number of times a color occurs in the picture) is not changed. For audio files the algorithm is the same, except that audio samples are used instead of pixels. The default encryption algorithm is Rijndael with a key size of 128 bits (which is AES \- the advanced encryption standard) in the cipher block chaining mode. If you do not trust this combination for whatever reason feel free to choose another algorithm/mode combination (information about all possible algorithms and modes is displayed by the \fBencinfo\fP command). The checksum is calculated using the CRC32 algorithm. .SH COMMANDS In this section the commands for steghide are listed. The first argument must always be one of these commands. You can supply additional arguments to the \fBembed\fP, \fBextract\fP and \fBinfo\fP commands. The other commands to not take any arguments. .TP .B "embed, --embed" Embed secret data in a cover file thereby creating a stego file. .TP .B "extract, --extract" Extract secret data from a stego file. .TP .B "info, --info" Display information about a cover or stego file. .TP .B "encinfo, --encinfo" Display a list of encryption algorithms and modes that can be used. No arguments required. .TP .B "version, --version" Display short version information. No arguments required. .TP .B "license, --license" Display steghide's license. No arguments required. .TP .B "help, --help" Display a help screen. No arguments required. .SH EMBEDDING You should use the \fBembed\fP command if you want to embed secret data in a cover file. The following arguments can be used with the \fBembed\fP command: .TP .B "-ef, --embedfile \fIfilename\fP" Specify the file that will be embedded (the file that contains the secret message). Note that steghide embeds the original file name in the stego file. When extracting data (see below) the default behaviour is to save the embedded file into the current directory under its original name. If this argument is omitted or \fIfilename\fP is \fB-\fP, steghide will read the secret data from standard input. .TP .B "-cf, --coverfile \fIfilename\fP" Specify the cover file that will be used to embed data. The cover file must be in one of the following formats: AU, BMP, JPEG or WAV. The file-format will be detected automatically based on header information (the extension is not relevant). If this argument is omitted or \fIfilename\fP is \fB-\fP, steghide will read the cover file from standard input. .TP .B "-sf, --stegofile \fIfilename\fP" Specify the name for the stego file that will be created. If this argument is omitted when calling steghide with the \fBembed\fP command, then the modifications to embed the secret data will be made directly to the cover file without saving it under a new name. .TP .B "-e, --encryption \fIalgo\fP [ \fImode\fP ] | \fImode\fP [ \fIalgo\fP ]" Specify encryption parameters. This option must be followed by one or two strings that identify an encryption algorithm and/or mode. You can get the names of all available algorithms and supported modes with the \fBencinfo\fP command. The default encryption is \fBrijndael-128\fP (AES) in the \fBcbc\fP mode. If you do not want to use any encryption, use \fB-e none\fP. .TP .B "-z, --compress \fIlevel\fP" Specify the compression level. The compression level can be any number in 1...9 where 1 means best speed and 9 means best compression. .TP .B "-Z, --dontcompress" Do not compress the secret data before embedding it. .TP .B "-K, --nochecksum" Do not embed a CRC32 checksum. You can use this if the secret data already contains some type of checksum or if you do not want to embed those extra 32 bits needed for the checksum. .TP .B "-N, --dontembedname" Do not embed the file name of the secret file. If this option is used, the extractor needs to specify a filename to tell steghide where to write the embedded data. .SH EXTRACTING If you have received a file that contains a message that has been embedded with steghide, use the \fBextract\fP command to extract it. The following arguments can be used with this command. .TP .B "-sf, --stegofile \fIfilename\fP" Specify the stego file (the file that contains embedded data). If this argument is omitted or \fIfilename\fP is \fB-\fP, steghide will read a stego file from standard input. .TP .B "-xf, --extractfile \fIfilename\fP" Create a file with the name \fIfilename\fP and write the data that is embedded in the stego file to it. This option overrides the filename that is embedded int the stego file. If this argument is omitted, the embedded data will be saved to the current directory under its original name. .SH GETTING INFORMATION ABOUT A COVER/STEGO FILE You can use the \fBinfo\fP command to get some information about a cover or stego file (for example the capacity). You might want to use this if you have received a file and you are not sure if it contains an embedded message or if you consider using a certain file as cover file and want to find out its capacity. The command line \fBsteghide info\fP \fI\fP will print information about \fI\fP and then ask you if you would like to get information about data that is embedded in that file. If you answer with yes you have to supply the passphrase that was used to embed the data in that file. You can also supply the \fB-p, --passphrase\fP argument (see below) to the \fBinfo\fP command which has the effect that steghide will automatically try to get information about the data that has been embedded using the given passphrase. .SH COMMON OPTIONS The following options can be used with all commands (where it makes sense). .TP .B "-p, --passphrase" Use the string following this argument as the passphrase. If your passphrase contains whitespace, you have to enclose it in quotes, for example: \fB-p "a very long passphrase"\fP. .TP .B "-v, --verbose" Display detailed information about the status of the embedding or extracting process. .TP .B "-q, --quiet" Supress information messages. .TP .B "-f, --force" Always overwrite existing files. .SH FILE NAME OPTIONS All file name arguments (\fB-cf\fP, \fB-ef\fP, \fB-sf\fP, \fB-xf\fP) also accept \fB-\fP as a filename which makes steghide use standard input or standard output (whichever makes sense). Omitting the corresponding file name argument will have the same effect as using \fB-\fP with two exceptions: If \fB-sf\fP is omitted for the embed command, then the modifications will be done directly in the cover file. If \fB-xf\fP is omitted for extraction, then the embedded data will be saved under the file name that is embedded in the stego file. So when you want to be sure that standard input/output is used, use \fB-\fP as filename. .SH EXAMPLES The basic usage is as follows: $ steghide embed -cf picture.jpg -ef secret.txt Enter passphrase: Re-Enter passphrase: embedding "secret.txt" in "picture.jpg"... done This command will embed the file secret.txt in the cover file picture.jpg. After you have embedded your secret data as shown above you can send the file picture.jpg to the person who should receive the secret message. The receiver has to use steghide in the following way: $ steghide extract -sf picture.jpg Enter passphrase: wrote extracted data to "secret.txt". If the supplied passphrase is correct, the contents of the original file secret.txt will be extracted from the stego file picture.jpg and saved in the current directory. If you have received a file that contains embedded data and you want to get some information about it before extracting it, use the info command: $ steghide info received_file.wav "received_file.wav": format: wave audio, PCM encoding capacity: 3.5 KB Try to get information about embedded data ? (y/n) y Enter passphrase: embedded file "secret.txt": size: 1.6 KB encrypted: rijndael-128, cbc compressed: yes After printing some general information about the stego file (format, capacity) you will be asked if steghide should try to get information about the embedded data. If you answer with yes you have to supply a passphrase. Steghide will then try to extract the embedded data with that passphrase and - if it succeeds - print some information about it. .SH RETURN VALUE Steghide returns 0 on success and 1 if a failure occured and it had to terminate before completion of the requested operation.

Se respetan las respectivas frecuencias de muestreo de colores por lo que sus adjuntos no se ven afectados por las pruebas estadísticas de primer orden. La versión actual de steghide es la 0.5.1 Características: *) compresión de datos adjuntos *) encriptado de datos adjuntos *) se adjunta la checksum para verificación de integridad de los datos extraídos *) reconoce archivos JPEG, BMP, WAV y AU Esteganografía : =============== Esteganografía significa literalmente, escritura encubierta. Su objetivo es ocultar el hecho de que se esta enviando información. Esto suele lograrse usando un archivo portada (algo extenso) y adjuntado un mensaje secreto (más corto) en este archivo. El resultado es un archivo de apariencia inocua (el archivo stego) que contiene el mensaje secreto. Compilación e Instalación : =========================== Dependencias : -------------- Deberíamos tener las siguientes librerias instaladas para usar steghide. * libmhash Una librería que tiene varios hash de algoritmos y claves criptográficas de generación de algoritmos. Steghide necesita esta librería para transformar el salvoconducto en una forma que pueda usarse como entrada de algoritmos criptográficos y esteganográficos. Puede obtenerse en: http://mhash.sourceforge.net/ * libmcrypt Una librería que tiene varios algoritmos de encriptado simétricos. Si compilamos steghide sin libmcrypt no podremos usar a steghide para encriptar datos antes de adjuntarlos ni extraer información encriptada (aunque conozcamos el salvoconducto apropiado). Puede obtenerse en: http://mcrypt.sourceforge.net/ * libjpeg Una librería que usa compactado de imágenes jpeg. Sin esta libería, no podremos adjuntar datos en archivos jpeg ni extraer datos en archivos jpeg. Puede obtenerse en: http://www.ijg.org/ * zlib Una librería de compactado sin pérdida de datos. Si compilamos steghide sin tener instalada esta librería no podremos usar steghide para compactar los datos antes de adjuntarlos ni extraer datos compactados de un archivo stego. Puede obtenerse en: http://www.gzip.org/zlib/ Libmhash es imprecindible para compilar steghide. Aunque se puede compilar sin las otras liberías se recomienda encarecidamente incluirlas ya que sino perdería muchas de sus grandes habilidades. Linux / Unix : -------------- Una vez desempaquetado la distribución fuente, ingresar los siguientes comandos: 1) ./configure 2) make 3) make check 4) make install (como root) Para mas información, ver las instrucciones de instalación genéricas en el archivo INSTALL que vino con la distribución. Si falla alguno de estos comandos, por favor, enviarme un email a la lista de correo de steghide (steghide-devel@lists.sourceforge.net) describiendo el error. Windows : --------- La forma más simple es descargar el binario precompilado (que incluye las versiones de Windows de todas las librerías necesarias) desde la sede de steghide: http://steghide.sourceforge.net/index.php Si quisiéramos compilar las fuentes necesitaremos un compilador de C++. La forma de compilar el código fuente dependerá del compilador que usemos: Por favor, consultar la documentación del compilador. Steghide puede compilarse con gcc en un entorno cygwin (http://www.cygwin.com/) que es una capa de emulación unix para Windows siguiendo el procedimiento antes descrito para la compilación Linux/Unix. Pronto Inicio : ============= He aquí algunos ejemplos de como puede usarse steghide. Echarle una mirada para hacernos una idea. Si necesitamos información más detallada por favor, leer la página man. Básicamente, se usa así: $ steghide embed -cf imagen.jpg -ef secreto.txt Ingrese salvoconducto: Re-ingrese el salvoconducto: adjuntando "secreto.txt" en "imagen.jpg"... hecho Este comando adjuntará el archivo secreto.txt en el archivo de portada imagen.jpg. Una vez adjuntado los datos secretos como se vió antes podemos enviar el archivo imagen.jpg a la persona que debería recibir el mensaje secreto. El receptor debe usar steghide de la siguiente manera: $ steghide extract -sf imagen.jpg Ingrese salvoconducto: los datos extraídos se grabaron en "secreto.txt". Si el salvoconducto declarado es el correcto, el contenido del archivo original secreto.txt se extraerá del archivo stego imagen.jpg y se grabará en el directorio actual. Si hemos recibido un archivo que contiene datos adjuntos y quisiéramos tener más información sobre el mismo antes de extraerlo, usaremos el comando info: $ steghide info archivo_recibido.wav "archivo_recibido.wav": formato: wave audio, PCM encoding capacidad: 3.5 KB ¿ Intento extraer información sobre los datos adjuntos? (y/n) y Ingrese salvoconducto: archivo adjunto "secreto.txt": tamaño: 1.6 KB encriptado: rijndael-128, cbc comprimido: si Luego de emitir algunos datos generales sobre el archivo stego (formato, capacidad) se nos preguntará si queremos que steghide obtenga información sobre los datos adjuntos. Si respondemos con yes tendremos que declarar un salvoconducto. Steghide entonces intentará extraer los datos adjuntos con ese salvoconducto y - si tiene 'éxito - emitirá un informe sobre el mismo.

The color- respectivly sample-frequencies are not changed thus making the embedding resistant against first-order statistical tests. The current version of steghide is 0.5.1 Features: *) compression of embedded data *) encryption of embedded data *) embedding of a checksum to verify the integrity of the extraced data *) support for JPEG, BMP, WAV and AU files Steganography : =============== Steganography literally means covered writing. Its goal is to hide the fact that communication is taking place. This is often achieved by using a (rather large) cover file and embedding the (rather short) secret message into this file. The result is a innocuous looking file (the stego file) that contains the secret message. Compilation and Installation : ============================== Dependencies : -------------- You should have the following libraries installed to use steghide. * libmhash A library that provides various hash algorithms and cryptographic key generation algorithms. Steghide needs this library to convert a passphrase into a form that can be used as input for cryptographic and steganographic algorithms. Available at: http://mhash.sourceforge.net/ * libmcrypt A library that provides a lot of symmetric encryption algorithms. If you compile steghide without libmcrypt you will not be able to use steghide to encrypt data before embedding nor to extract encrypted data (even if you know the correct passphrase). Available at: http://mcrypt.sourceforge.net/ * libjpeg A library implementing jpeg image compression. Without this library you will not be able to embed data in jpeg files nor to extract data from jpeg files. Available at: http://www.ijg.org/ * zlib A lossless data compression library. If you compile steghide without having this library installed you will not be able to use steghide to compress data before embedding nor to extract compressed data from a stego-file. Available at: http://www.gzip.org/zlib/ Libmhash is absolutely required to compile steghide. While you can compile it without the other libraries they are highly recommended as major functionality will not be available without them. Linux / Unix : -------------- After unpacking the source distribution, enter the following commands: 1) ./configure 2) make 3) make check 4) make install (as root) For more information see the generic installation instructions in the file INSTALL that came with the distribution. If any of these commands fails, please send a mail to the steghide development mailing list (steghide-devel@lists.sourceforge.net) describing the error. Windows : --------- The easiest way is to download the precompiled binary (including Windows versions of the necessary libraries) from the steghide website at: http://steghide.sourceforge.net/index.php If you want to compile the sources yourself you need a C++ compiler. How you need to compile the source code depends on the compiler you are using: Please consult your compiler's documentation. Steghide can be compiled with gcc in the cygwin environment (http://www.cygwin.com/) which is a unix emulation layer for Windows using the procedure mentioned above for the Linux/Unix compilation. Quick-Start : ============= Here are some examples of how steghide can be used. Take a look at these to get a first impression. If you want more detailed information please read the manpage. The basic usage is as follows: $ steghide embed -cf picture.jpg -ef secret.txt Enter passphrase: Re-Enter passphrase: embedding "secret.txt" in "picture.jpg"... done This command will embed the file secret.txt in the cover file picture.jpg. After you have embedded your secret data as shown above you can send the file picture.jpg to the person who should receive the secret message. The receiver has to use steghide in the following way: $ steghide extract -sf picture.jpg Enter passphrase: wrote extracted data to "secret.txt". If the supplied passphrase is correct, the contents of the original file secret.txt will be extracted from the stego file picture.jpg and saved in the current directory. If you have received a file that contains embedded data and you want to get some information about it before extracting it, use the info command: $ steghide info received_file.wav "received_file.wav": format: wave audio, PCM encoding capacity: 3.5 KB Try to get information about embedded data ? (y/n) y Enter passphrase: embedded file "secret.txt": size: 1.6 KB encrypted: rijndael-128, cbc compressed: yes After printing some general information about the stego file (format, capacity) you will be asked if steghide should try to get information about the embedded data. If you answer with yes you have to supply a passphrase. Steghide will then try to extract the embedded data with that passphrase and - if it succeeds - print some information about it.

Here is a matrix of mmap possibilities: mmap private not fixed mmap private fixed at somewhere currently unmapped mmap private fixed at somewhere already mapped mmap shared not fixed mmap shared fixed at somewhere currently unmapped mmap shared fixed at somewhere already mapped For private mappings, we should verify that changes cannot be read() back from the file, nor mmap's back from the file at a different address. (There have been systems where private was not correctly implemented like the infamous i386 svr4.0, and systems where the VM page cache was not coherent with the file system buffer cache like early versions of FreeBSD and possibly contemporary NetBSD.) For shared mappings, we should conversely verify that changes get propagated back to all the places they're supposed to be. Grep wants private fixed already mapped.

The color- respectivly sample-frequencies are not changed thus making the embedding resistant against first-order statistical tests. Features of steghide include compression and encryption of embedded data, embedding of a checksum to verify the integrity of the extracted data and support for jpeg, bmp, wav and au files. %prep %setup ./configure --prefix=/usr %build make %install make install %files %doc ABOUT-NLS BUGS COPYING CREDITS HISTORY INSTALL README TODO /usr/bin/steghide /usr/man/man1/steghide.1 steghide-0.5.1/config.sub0000755000076400001440000007160307634203260010766 #! /bin/sh # Configuration validation subroutine script. # Copyright (C) 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, # 2000, 2001, 2002 Free Software Foundation, Inc. timestamp='2002-11-30' # This file is (in principle) common to ALL GNU software. # The presence of a machine in this file suggests that SOME GNU software # can handle that machine.

The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, a file `config.cache' that saves the results of its tests to speed up reconfiguring, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.in' is used to create `configure' by a program called `autoconf'. You only need `configure.in' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. You can give `configure' initial values for variables by setting them in the environment. Using a Bourne-compatible shell, you can do that on the command line like this: CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure Or on systems that have the `env' program, you can do it like this: env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of `make' that supports the `VPATH' variable, such as GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. If you have to use a `make' that does not supports the `VPATH' variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' will install the package's files in `/usr/local/bin', `/usr/local/man', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PATH'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give `configure' the option `--exec-prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=PATH' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' can not figure out automatically, but needs to determine by the type of host the package will run on. Usually `configure' can figure that out, but if it prints a message saying it can not guess the host type, give it the `--host=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name with three fields: CPU-COMPANY-SYSTEM See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the host type. If you are building compiler tools for cross-compiling, you can also use the `--target=TYPE' option to select the type of system they will produce code for and the `--build=TYPE' option to select the type of system on which you are compiling the package. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Operation Controls ================== `configure' recognizes the following options to control how it operates. `--cache-file=FILE' Use and save the results of the tests in FILE instead of `./config.cache'. Set FILE to `/dev/null' to disable caching, for debugging `configure'. `--help' Print a summary of the options to `configure', and exit. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `--version' Print the version of Autoconf used to generate the `configure' script, and exit. `configure' also accepts some other, not widely useful, options. steghide-0.5.1/ABOUT-NLS0000644000076400001440000006015707735006035010237 Notes on the Free Translation Project ************************************* Free software is going international! The Free Translation Project is a way to get maintainers of free software, translators, and users all together, so that will gradually become able to speak many languages. A few packages already provide translations for their messages. If you found this `ABOUT-NLS' file inside a distribution, you may assume that the distributed package does use GNU `gettext' internally, itself available at your nearest GNU archive site. But you do _not_ need to install GNU `gettext' prior to configuring, installing or using this package with messages translated. Installers will find here some useful hints. These notes also explain how users should proceed for getting the programs to use the available translations. They tell how people wanting to contribute and work at translations should contact the appropriate team. When reporting bugs in the `intl/' directory or bugs which may be related to internationalization, you should tell about the version of `gettext' which is used. The information can be found in the `intl/VERSION' file, in internationalized packages. Quick configuration advice ========================== If you want to exploit the full power of internationalization, you should configure it using ./configure --with-included-gettext to force usage of internationalizing routines provided within this package, despite the existence of internationalizing capabilities in the operating system where this package is being installed. So far, only the `gettext' implementation in the GNU C library version 2 provides as many features (such as locale alias, message inheritance, automatic charset conversion or plural form handling) as the implementation here. It is also not possible to offer this additional functionality on top of a `catgets' implementation. Future versions of GNU `gettext' will very likely convey even more functionality. So it might be a good idea to change to GNU `gettext' as soon as possible. So you need _not_ provide this option if you are using GNU libc 2 or you have installed a recent copy of the GNU gettext package with the included `libintl'. INSTALL Matters =============== Some packages are "localizable" when properly installed; the programs they contain can be made to speak your own native language. Most such packages use GNU `gettext'. Other packages have their own ways to internationalization, predating GNU `gettext'. By default, this package will be installed to allow translation of messages. It will automatically detect whether the system already provides the GNU `gettext' functions. If not, the GNU `gettext' own library will be used. This library is wholly contained within this package, usually in the `intl/' subdirectory, so prior installation of the GNU `gettext' package is _not_ required. Installers may use special options at configuration time for changing the default behaviour. The commands: ./configure --with-included-gettext ./configure --disable-nls will respectively bypass any pre-existing `gettext' to use the internationalizing routines provided within this package, or else, _totally_ disable translation of messages. When you already have GNU `gettext' installed on your system and run configure without an option for your new package, `configure' will probably detect the previously built and installed `libintl.a' file and will decide to use this. This might be not what is desirable. You should use the more recent version of the GNU `gettext' library. I.e. if the file `intl/VERSION' shows that the library which comes with this package is more recent, you should use ./configure --with-included-gettext to prevent auto-detection. The configuration process will not test for the `catgets' function and therefore it will not be used. The reason is that even an emulation of `gettext' on top of `catgets' could not provide all the extensions of the GNU `gettext' library. Internationalized packages have usually many `po/LL.po' files, where LL gives an ISO 639 two-letter code identifying the language. Unless translations have been forbidden at `configure' time by using the `--disable-nls' switch, all available translations are installed together with the package. However, the environment variable `LINGUAS' may be set, prior to configuration, to limit the installed set. `LINGUAS' should then contain a space separated list of two-letter codes, stating which languages are allowed. Using This Package ================== As a user, if your language has been installed for this package, you only have to set the `LANG' environment variable to the appropriate `LL_CC' combination. Here `LL' is an ISO 639 two-letter language code, and `CC' is an ISO 3166 two-letter country code. For example, let's suppose that you speak German and live in Germany. At the shell prompt, merely execute `setenv LANG de_DE' (in `csh'), `export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash'). This can be done from your `.login' or `.profile' file, once and for all. You might think that the country code specification is redundant. But in fact, some languages have dialects in different countries. For example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The country code serves to distinguish the dialects. The locale naming convention of `LL_CC', with `LL' denoting the language and `CC' denoting the country, is the one use on systems based on GNU libc. On other systems, some variations of this scheme are used, such as `LL' or `LL_CC.ENCODING'. You can get the list of locales supported by your system for your country by running the command `locale -a | grep '^LL''. Not all programs have translations for all languages. By default, an English message is shown in place of a nonexistent translation. If you understand other languages, you can set up a priority list of languages. This is done through a different environment variable, called `LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG' for the purpose of message handling, but you still need to have `LANG' set to the primary language; this is required by other parts of the system libraries. For example, some Swedish users who would rather read translations in German than English for when Swedish is not available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'. In the `LANGUAGE' environment variable, but not in the `LANG' environment variable, `LL_CC' combinations can be abbreviated as `LL' to denote the language's main dialect. For example, `de' is equivalent to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT' (Portuguese as spoken in Portugal) in this context. Translating Teams ================= For the Free Translation Project to be a success, we need interested people who like their own language and write it well, and who are also able to synergize with other translators speaking the same language. Each translation team has its own mailing list. The up-to-date list of teams can be found at the Free Translation Project's homepage, `http://www.iro.umontreal.ca/contrib/po/HTML/', in the "National teams" area. If you'd like to volunteer to _work_ at translating messages, you should become a member of the translating team for your own language. The subscribing address is _not_ the same as the list itself, it has `-request' appended. For example, speakers of Swedish can send a message to `sv-request@li.org', having this message body: subscribe Keep in mind that team members are expected to participate _actively_ in translations, or at solving translational difficulties, rather than merely lurking around. If your team does not exist yet and you want to start one, or if you are unsure about what to do or how to get started, please write to `translation@iro.umontreal.ca' to reach the coordinator for all translator teams. The English team is special. It works at improving and uniformizing the terminology in use. Proven linguistic skill are praised more than programming skill, here. Available Packages ================== Languages are not equally supported in all packages. The following matrix shows the current state of internationalization, as of August 2002. The matrix shows, in regard of each package, for which languages PO files have been submitted to translation coordination, with a translation percentage of at least 50%.

than the number of visible blocks let us expect. This is because a few extra PO files are used for implementing regional variants of languages, or language dialects. For a PO file in the matrix above to be effective, the package to which it applies should also have been internationalized and distributed as such by its maintainer. There might be an observable lag between the mere existence a PO file and its wide availability in a distribution. If August 2002 seems to be old, you may fetch a more recent copy of this `ABOUT-NLS' file on most GNU archive sites. The most up-to-date matrix with full percentage details can be found at `http://www.iro.umontreal.ca/contrib/po/HTML/matrix.html'. Using `gettext' in new packages =============================== If you are writing a freely available program and want to internationalize it you are welcome to use GNU `gettext' in your package. Of course you have to respect the GNU Library General Public License which covers the use of the GNU `gettext' library. This means in particular that even non-free programs can use `libintl' as a shared library, whereas only free software can use `libintl' as a static library or use modified versions of `libintl'. Once the sources are changed appropriately and the setup can handle to use of `gettext' the only thing missing are the translations. The Free Translation Project is also available for packages which are not developed inside the GNU project. Therefore the information given above applies also for every other Free Software Project. Contact `translation@iro.umontreal.ca' to make the `.pot' files available to the translation teams. steghide-0.5.1/COPYING0000644000076400001440000004307207371045270010040 GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave, Cambridge, MA 02139, USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19yy name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. steghide-0.5.1/CREDITS0000644000076400001440000000157707741743627010045 Stefan Hetzl author, maintainer I would like to thank...
