DDEESSCCRRIIPPTTIIOONN _f_c_r_a_c_k_z_i_p searches each zipfile given for encrypted files and tries to guess the password. All files must be encrypted with the same password, the more files you provide, the better. OOPPTTIIOONNSS --hh,, ----hheellpp Prints the version number and (hopefully) some helpful insights. --vv,, ----vveerrbboossee Each -v makes the program more verbose. --bb,, ----bbrruuttee--ffoorrccee Select brute force mode. This tries all possible combinations of the letters you specify. --DD,, ----ddiiccttiioonnaarryy Select dictionary mode. In this mode, fcrackzip will read pass- words from a file, which must contain one password per line and should be alphabetically sorted (e.g. using ssoorrtt((11))). --cc,, ----cchhaarrsseett cchhaarraacctteerrsseett--ssppeecciiffiiccaattiioonn Select the characters to use in brute-force cracking.

This way you can include any character except binary null (at least under unix). For example, a1:$% selects lowercase characters, digits and the dollar and percent signs. --pp,, ----iinniitt--ppaasssswwoorrdd ssttrriinngg Set initial (starting) password for brute-force searching to _s_t_r_i_n_g, or use the file with the name _s_t_r_i_n_g to supply passwords for dictionary searching. --ll,, ----lleennggtthh mmiinn[[--mmaaxx]] Use an initial password of length min, and check all passwords upto passwords of length max (including).

ZZIIPP PPAASSSSWWOORRDD BBAASSIICCSS Have you ever mis-typed a password for unzip? Unzip reacted pretty fast with incorrect password, _w_i_t_h_o_u_t decrypting the whole file. While the encryption algorithm used by zip is relatively secure, PK made cracking easy by providing hooks for very fast password-checking, directly in the zip file. Understanding these is crucial to zip password cracking: For each password that is tried, the first twelve bytes of the file are decrypted. Depending on the version of zip used to encrypt the file (more on that later), the first ten or eleven bytes are random, fol- lowed by one or two bytes whose values are stored elsewhere in the zip file, i.e. are known beforehand. If these last bytes don't have the correct (known) value, the password is definitely wrong. If the bytes are correct, the password _m_i_g_h_t be correct, but the only method to find out is to unzip the file and compare the uncompressed length and crcs. Earlier versions of pkzip (1.xx) (and, incidentally, many zip clones for other operating systems!) stored two known bytes. Thus the error rate was roughly 1/2^16 = 0.01%. PKWARE improved (interesting what industry calls improved) the security of their format by only including one byte, so the possibility of false passwords is now raised to 0.4%. Unfortunately, there is no real way to distinguish one byte from two byte formats, so we have to be conservative. BBRRUUTTEE FFOORRCCEE MMOODDEE By default, brute force starts at the given starting password, and suc- cessively tries all combinations until they are exhausted, printing all passwords that it detects, together with a rough correctness indicator. The starting password given by the _-_p switch determines the length. fcrackzip will not currently increase the password length automati- cally, unless the _-_l switch is used. DDIICCTTIIOONNAARRYY MMOODDEE This mode is similar to brute force mode, but instead of generating passwords using a given set of characters and a length, the passwords will be read from a file that you have to specify using the _-_p switch. CCPP MMAASSKK A CP mask is a method to obscure images or parts of images using a password. These obscured images can be restored even when saved as JPEG files. In most of these files the password is actually hidden and can be decoded easily (using one of the many available viewer and mask- ing programs, e.g. xv). If you convert the image the password, however, is lost. The ccppmmaasskk crack method can be used to brute-force these images. Instead of a zip file you supply the obscured part (and nothing else) of the image in the PPPPMM-Image Format (xxvv and other viewers can easily do this). The ccppmmaasskk method can only cope with password composed of uppercase letters, so be sure to supply the ----cchhaarrsseett AA or equivalent option, together with a suitable initialization password.

PPEERRFFOORRMMAANNCCEE _f_z_c, which seems to be widely used as a fast password cracker, claims to make 204570 checks per second on my machine (measured under plain dos w/o memory manager). _f_c_r_a_c_k_z_i_p, being written in C and not in assembler, naturally is slower. Measured on a slightly loaded unix (same machine), its 12 per- cent slower (the compiler used was _p_g_c_c, from hhttttpp::////wwwwww..ggcccc..mmll..oorrgg//). To remedy this a bit, I converted small parts of the encryption core to x86 assembler (it will still compile on non x86 machines), and now its about 4-12 percent faster than _f_z_c (again, the _f_c_r_a_c_k_z_i_p performance was measured under a multitasking os, so there are inevitably some meaurement errors), so there shouldn't be a tempting reason to switch to other programs. Further improvements are definitely possible: _f_z_c took 4 years to get into shape, while fcrackzip was hacked together in under 10 hours. And not to forget you have the source, while other programs (like _f_z_c), even come as an _e_n_c_r_y_p_t_e_d _._e_x_e file (maybe because their programmers are afraid of other people could having a look at their lack of pro- gramming skills? nobody knows...) RRAATTIIOONNAALLEE The reason I wrote _f_c_r_a_c_k_z_i_p was NNOOTT to have the fastest zip cracker available, but to provide a _p_o_r_t_a_b_l_e, _f_r_e_e (thus _e_x_t_e_n_s_i_b_l_e), but still _f_a_s_t zip password cracker. I was really pissed of with that dumb, nonextendable zipcrackers that were either slow, were too limited, or wouldn't run in the background (say, under unix). (And you can't run them on your superfast 600Mhz Alpha). BBUUGGSS No automatic unzip checking. Stop/resume facility is missing. Should be able to distinguish between files with 16 bit stored CRCs and 8 bit stored CRCs. The benchmark does not work on all systems. It's still early alpha. Method "cpmask" only accepts ppms. Could be faster. AAUUTTHHOORR _f_c_r_a_c_k_z_i_p was written by Marc Lehmann .

NAME

fcrackzip - a Free/Fast Zip Password Cracker  

SYNOPSIS

fcrackzip [-bDBchVvplum2] [--brute-force] [--dictionary] [--benchmark] [--charset characterset] [--help] [--validate] [--verbose] [--init-password string/path] [--length min-max] [--use-unzip] [--method name] [--modulo r/m] file...  

DESCRIPTION

fcrackzip searches each zipfile given for encrypted files and tries to guess the password. All files must be encrypted with the same password, the more files you provide, the better.  

OPTIONS

-h, --help
Prints the version number and (hopefully) some helpful insights.
-v, --verbose
Each -v makes the program more verbose.
-b, --brute-force
Select brute force mode. This tries all possible combinations of the letters you specify.
-D, --dictionary
Select dictionary mode. In this mode, fcrackzip will read passwords from a file, which must contain one password per line and should be alphabetically sorted (e.g. using (1)).
-c, --charset characterset-specification
Select the characters to use in brute-force cracking. Must be one of 

  a   include all lowercase characters [a-z]
  A   include all uppercase characters [A-Z]
  1   include the digits [0-9]
  !   include [!:$%&/()=?{[]}+*~#]
  :   the following characters upto the end of the spe-
      cification string are included in the character set.
      This way you can include any character except binary
      null (at least under unix).

For example, a1:$% selects lowercase characters, digits and the dollar and percent signs.

-p, --init-password string
Set initial (starting) password for brute-force searching to string, or use the file with the name string to supply passwords for dictionary searching.
-l, --length min[-max]
Use an initial password of length min, and check all passwords upto passwords of length max (including). You can omit the max parameter.
-u, --use-unzip
Try to decompress the first file by calling unzip with the guessed password. This weeds out false positives when not enough files have been given.
-m, --method name
Use method number "name" instead of the default cracking method. The switch --help will print a list of available methods. Use --benchmark to see which method does perform best on your machine. The name can also be the number of the method to use.
-2, --modulo r/m
Calculate only r/m of the password. Not yet supported.
-B, --benchmark
Make a small benchmark, the output is nearly meaningless.
-V, --validate
Make some basic checks wether the cracker works.
 

ZIP PASSWORD BASICS

Have you ever mis-typed a password for unzip? Unzip reacted pretty fast with 'incorrect password', without decrypting the whole file. While the encryption algorithm used by zip is relatively secure, PK made cracking easy by providing hooks for very fast password-checking, directly in the zip file. Understanding these is crucial to zip password cracking:

For each password that is tried, the first twelve bytes of the file are decrypted. Depending on the version of zip used to encrypt the file (more on that later), the first ten or eleven bytes are random, followed by one or two bytes whose values are stored elsewhere in the zip file, i.e. are known beforehand. If these last bytes don't have the correct (known) value, the password is definitely wrong. If the bytes are correct, the password might be correct, but the only method to find out is to unzip the file and compare the uncompressed length and crc's.

Earlier versions of pkzip (1.xx) (and, incidentally, many zip clones for other operating systems!) stored two known bytes. Thus the error rate was roughly 1/2^16 = 0.01%. PKWARE 'improved' (interesting what industry calls improved) the security of their format by only including one byte, so the possibility of false passwords is now raised to 0.4%. Unfortunately, there is no real way to distinguish one byte from two byte formats, so we have to be conservative.  

BRUTE FORCE MODE

By default, brute force starts at the given starting password, and successively tries all combinations until they are exhausted, printing all passwords that it detects, together with a rough correctness indicator.

The starting password given by the -p switch determines the length. fcrackzip will not currently increase the password length automatically, unless the -l switch is used.  

DICTIONARY MODE

This mode is similar to brute force mode, but instead of generating passwords using a given set of characters and a length, the passwords will be read from a file that you have to specify using the -p switch.  

CP MASK

A CP mask is a method to obscure images or parts of images using a password. These obscured images can be restored even when saved as JPEG files. In most of these files the password is actually hidden and can be decoded easily (using one of the many available viewer and masking programs, e.g. xv). If you convert the image the password, however, is lost. The cpmask crack method can be used to brute-force these images. Instead of a zip file you supply the obscured part (and nothing else) of the image in the PPM-Image Format (xv and other viewers can easily do this).

The cpmask method can only cope with password composed of uppercase letters, so be sure to supply the --charset A or equivalent option, together with a suitable initialization password.  

EXAMPLES

fcrackzip -c a -p aaaaaa sample.zip
checks the encrypted files in sample.zip for all lowercase 6 character passwords (aaaaaa ... abaaba ... ghfgrg ... zzzzzz).
fcrackzip --method cpmask --charset A --init AAAA test.ppm
checks the obscured image test.ppm for all four character passwords. -TP fcrackzip -D -p passwords.txt sample.zip check for every password listed in the file passwords.txt.
 

PERFORMANCE

fzc, which seems to be widely used as a fast password cracker, claims to make 204570 checks per second on my machine (measured under plain dos w/o memory manager).

fcrackzip, being written in C and not in assembler, naturally is slower. Measured on a slightly loaded unix (same machine), it's 12 percent slower (the compiler used was pgcc, from http://www.gcc.ml.org/).

To remedy this a bit, I converted small parts of the encryption core to x86 assembler (it will still compile on non x86 machines), and now it's about 4-12 percent faster than fzc (again, the fcrackzip performance was measured under a multitasking os, so there are inevitably some meaurement errors), so there shouldn't be a tempting reason to switch to other programs.

Further improvements are definitely possible: fzc took 4 years to get into shape, while fcrackzip was hacked together in under 10 hours. And not to forget you have the source, while other programs (like fzc), even come as an encrypted .exe file (maybe because their programmers are afraid of other people could having a look at their lack of programming skills? nobody knows...)  

RATIONALE

The reason I wrote fcrackzip was NOT to have the fastest zip cracker available, but to provide a portable, free (thus extensible), but still fast zip password cracker. I was really pissed of with that dumb, nonextendable zipcrackers that were either slow, were too limited, or wouldn't run in the background (say, under unix). (And you can't run them on your superfast 600Mhz Alpha).  

BUGS

No automatic unzip checking.

Stop/resume facility is missing.

Should be able to distinguish between files with 16 bit stored CRC's and 8 bit stored CRC's.

The benchmark does not work on all systems.

It's still early alpha.

Method "cpmask" only accepts ppms.

Could be faster.

It's password has 6 lower case characters, and fcrackzip will find it (and a number of false positives) with fcrackzip -b -c a -p aaaaaa ./noradi.zip which will take between one and thirty minutes on typical machines.

All files must be encrypted with the same password, the more files you provide, the better. .SS OPTIONS .TP .B \-h, \--help Prints the version number and (hopefully) some helpful insights. .TP .B \-v, \--verbose Each -v makes the program more verbose. .TP .B \-b, \--brute-force Select brute force mode. This tries all possible combinations of the letters you specify. .TP .B \-D, \--dictionary Select dictionary mode. In this mode, fcrackzip will read passwords from a file, which must contain one password per line and should be alphabetically sorted (e.g. using \fBsort(1)\fR). .TP .B \-c, \--charset characterset-specification Select the characters to use in brute-force cracking. Must be one of .nf a include all lowercase characters [a-z] A include all uppercase characters [A-Z] 1 include the digits [0-9] ! include [!:$%&/()=?{[]}+*~#] : the following characters upto the end of the spe- cification string are included in the character set. This way you can include any character except binary null (at least under unix). .fi For example, a1:$% selects lowercase characters, digits and the dollar and percent signs. .TP .B \-p, \--init-password string Set initial (starting) password for brute-force searching to \fIstring\fR, or use the file with the name \fIstring\fR to supply passwords for dictionary searching. .TP .B \-l, \--length min[-max] Use an initial password of length min, and check all passwords upto passwords of length max (including). You can omit the max parameter. .TP .B \-u, \--use-unzip Try to decompress the first file by calling unzip with the guessed password. This weeds out false positives when not enough files have been given. .TP .B \-m, \--method name Use method number "name" instead of the default cracking method. The switch \fB--help\fR will print a list of available methods. Use \fB--benchmark\fR to see which method does perform best on your machine. The \fBname\fR can also be the number of the method to use. .TP .B \-2, \--modulo r/m Calculate only r/m of the password. Not yet supported. .TP .B \-B, \--benchmark Make a small benchmark, the output is nearly meaningless. .TP .B -V, \--validate Make some basic checks wether the cracker works. .SH ZIP PASSWORD BASICS Have you ever mis-typed a password for unzip? Unzip reacted pretty fast with \'incorrect password\', \fIwithout\fR decrypting the whole file. While the encryption algorithm used by zip is relatively secure, PK made cracking easy by providing hooks for very fast password-checking, directly in the zip file. Understanding these is crucial to zip password cracking: For each password that is tried, the first twelve bytes of the file are decrypted. Depending on the version of zip used to encrypt the file (more on that later), the first ten or eleven bytes are random, followed by one or two bytes whose values are stored elsewhere in the zip file, i.e. are known beforehand. If these last bytes don't have the correct (known) value, the password is definitely wrong. If the bytes are correct, the password \fImight\fR be correct, but the only method to find out is to unzip the file and compare the uncompressed length and crc\'s. Earlier versions of pkzip (1.xx) (and, incidentally, many zip clones for other operating systems!) stored two known bytes. Thus the error rate was roughly 1/2^16 = 0.01%. PKWARE \'improved\' (interesting what industry calls improved) the security of their format by only including one byte, so the possibility of false passwords is now raised to 0.4%. Unfortunately, there is no real way to distinguish one byte from two byte formats, so we have to be conservative. .SH BRUTE FORCE MODE By default, brute force starts at the given starting password, and successively tries all combinations until they are exhausted, printing all passwords that it detects, together with a rough correctness indicator. The starting password given by the \fI-p\fR switch determines the length. fcrackzip will not currently increase the password length automatically, unless the \fI-l\fR switch is used. .SH DICTIONARY MODE This mode is similar to brute force mode, but instead of generating passwords using a given set of characters and a length, the passwords will be read from a file that you have to specify using the \fI-p\fR switch. .SH CP MASK A CP mask is a method to obscure images or parts of images using a password. These obscured images can be restored even when saved as JPEG files. In most of these files the password is actually hidden and can be decoded easily (using one of the many available viewer and masking programs, e.g. xv). If you convert the image the password, however, is lost. The \fBcpmask\fR crack method can be used to brute-force these images. Instead of a zip file you supply the obscured part (and nothing else) of the image in the \fBPPM\fR-Image Format (\fBxv\fR and other viewers can easily do this). The \fBcpmask\fR method can only cope with password composed of uppercase letters, so be sure to supply the \fB--charset A\fR or equivalent option, together with a suitable initialization password. .SH EXAMPLES .TP .B fcrackzip -c a -p aaaaaa sample.zip checks the encrypted files in sample.zip for all lowercase 6 character passwords (aaaaaa ... abaaba ... ghfgrg ... zzzzzz). .TP .B fcrackzip --method cpmask --charset A --init AAAA test.ppm checks the obscured image \fBtest.ppm\fR for all four character passwords. -TP .B fcrackzip -D -p passwords.txt sample.zip check for every password listed in the file \fBpasswords.txt\fR. .SH PERFORMANCE \fIfzc\fR, which seems to be widely used as a fast password cracker, claims to make 204570 checks per second on my machine (measured under plain dos w/o memory manager). \fIfcrackzip\fR, being written in C and not in assembler, naturally is slower. Measured on a slightly loaded unix (same machine), it\'s 12 percent slower (the compiler used was \fIpgcc\fR, from \fBhttp://www.gcc.ml.org/\fR). To remedy this a bit, I converted small parts of the encryption core to x86 assembler (it will still compile on non x86 machines), and now it\'s about 4-12 percent faster than \fIfzc\fR (again, the \fIfcrackzip\fR performance was measured under a multitasking os, so there are inevitably some meaurement errors), so there shouldn't be a tempting reason to switch to other programs. Further improvements are definitely possible: \fIfzc\fR took 4 years to get into shape, while fcrackzip was hacked together in under 10 hours. And not to forget you have the source, while other programs (like \fIfzc\fR), even come as an \fIencrypted .exe\fR file (maybe because their programmers are afraid of other people could having a look at their lack of programming skills? nobody knows...) .SH RATIONALE The reason I wrote \fIfcrackzip\fR was \fBNOT\fR to have the fastest zip cracker available, but to provide a \fIportable\fR, \fIfree\fR (thus \fIextensible\fR), but still \fIfast\fR zip password cracker. I was really pissed of with that dumb, nonextendable zipcrackers that were either slow, were too limited, or wouldn't run in the background (say, under unix). (And you can't run them on your superfast 600Mhz Alpha). .SH BUGS No automatic unzip checking. .PP Stop/resume facility is missing. .PP Should be able to distinguish between files with 16 bit stored CRC\'s and 8 bit stored CRC\'s. .PP \The benchmark does not work on all systems. .PP It's still early alpha. .PP Method "cpmask" only accepts ppms. .PP Could be faster. .SH AUTHOR \fIfcrackzip\fR was written by Marc Lehmann .

If an element of ARGV starts with '-', and is not exactly "-" or "--", then it is an option element. The characters of this element (aside from the initial '-') are option characters. If `getopt' is called repeatedly, it returns successively each of the option characters from each of the option elements. If `getopt' finds another option character, it returns that character, updating `optind' and `nextchar' so that the next call to `getopt' can resume the scan with the following option character or ARGV-element. If there are no more option characters, `getopt' returns `EOF'. Then `optind' is the index in ARGV of the first ARGV-element that is not an option. (The ARGV-elements have been permuted so that those that are not options now come last.) OPTSTRING is a string containing the legitimate option characters. If an option character is seen that is not listed in OPTSTRING, return '?' after printing an error message. If you set `opterr' to zero, the error message is suppressed but we still return '?'. If a char in OPTSTRING is followed by a colon, that means it wants an arg, so the following text in the same ARGV-element, or the text of the following ARGV-element, is returned in `optarg'. Two colons mean an option that wants an optional arg; if there is text in the current ARGV-element, it is returned in `optarg', otherwise `optarg' is set to zero. If OPTSTRING starts with `-' or `+', it requests different methods of handling the non-option ARGV-elements. See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above. Long-named options begin with `--' instead of `-'. Their names may be abbreviated as long as the abbreviation is unique or is an exact match for some defined option. If they have an argument, it follows the option name in the same ARGV-element, separated from the option name by a `=', or else the in next ARGV-element. When `getopt' finds a long-named option, it returns 0 if that option's `flag' field is nonzero, the value of the option's `val' field if the `flag' field is zero. The elements of ARGV aren't really const, because we permute them. But we pretend they're const in the prototype to be compatible with other systems. LONGOPTS is a vector of `struct option' terminated by an element containing a name which is zero. LONGIND returns the index in LONGOPT of the long-named option found.

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. fcrackzip-1.0/zipcrack.c0000664000000000000000000001532607621414704012205 00000000000000/* * zipcrack.c - where the 'crack' routine is located */ /* * guiding comments for gencrack.pl * * MTH cpmask init_cpmask crack_cpmask load_img * * LCL init_crack_pw crack_pw * LOD load_zip * * ARC ARCH_i386 * DEF USE_MULT_TAB * DEF TARGET_CPU 0 $ 5 $ 6 * DFT TARGET_CPU==COMPILE_CPU && USE_MULT_TAB * DEP defined(__i386__) || defined(__i386) || defined(i386) * * DEF USE_MULT_TAB * DFT USE_MULT_TAB * DEP 1 * * END */ #include "crc32.h" #undef USE_GCC_X86_ASM #define USE_GCC_X86_ASM (ARCH_i386 && USE_GCC_ASM && USE_MULT_TAB) static void init_crack_pw (void) { #if USE_MULT_TAB u16 t;

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 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) 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., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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) year 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.
