The implementation itself is pure Perl, although the heavy-duty mathematics underneath are provided by the *Math::Pari* library. This package provides DSA signing, signature verification, and key generation. USAGE The *Crypt::DSA* public interface is similar to that of *Crypt::RSA*. This was done intentionally. Crypt::DSA->new Constructs a new *Crypt::DSA* object. At the moment this isn't particularly useful in itself, other than being the object you need to do much else in the system. Returns the new object. $key = $dsa->keygen(%arg) Generates a new set of DSA keys, including both the public and private portions of the key. *%arg* can contain: * Size The size in bits of the *p* value to generate. The *q* and *g* values are always 160 bits each. This argument is mandatory. * Seed A seed with which *q* generation will begin. If this seed does not lead to a suitable prime, it will be discarded, and a new random seed chosen in its place, until a suitable prime can be found. This is entirely optional, and if not provided a random seed will be generated automatically. * Verbosity Should be either 0 or 1. A value of 1 will give you a progress meter during *p* and *q* generation--this can be useful, since the process can be relatively long. The default is 0. $signature = $dsa->sign(%arg) Signs a message (or the digest of a message) using the private portion of the DSA key and returns the signature. The return value--the signature--is a *Crypt::DSA::Signature* object. *%arg* can include: * Digest A digest to be signed. The digest should be 20 bytes in length or less. You must provide either this argument or *Message* (see below). * Key The *Crypt::DSA::Key* object with which the signature will be generated. Should contain a private key attribute (*priv_key*). This argument is required. * Message A plaintext message to be signed. If you provide this argument, *sign* will first produce a SHA1 digest of the plaintext, then use that as the digest to sign. Thus writing my $sign = $dsa->sign(Message => $message, ... ); is a shorter way of writing use Digest::SHA1 qw( sha1 ); my $sig = $dsa->sign(Digest => sha1( $message ), ... ); $verified = $dsa->verify(%arg) Verifies a signature generated with *sign*. Returns a true value on success and false on failure. *%arg* can contain: * Key Key of the signer of the message; a *Crypt::DSA::Key* object. The public portion of the key is used to verify the signature. This argument is required. * Signature The signature itself. Should be in the same format as returned from *sign*, a *Crypt::DSA::Signature* object. This argument is required. * Digest The original signed digest whose length is less than or equal to 20 bytes. Either this argument or *Message* (see below) must be present. * Message As above in *sign*, the plaintext message that was signed, a string of arbitrary length. A SHA1 digest of this message will be created and used in the verification process. TODO Add ability to munge format of keys. For example, read/write keys from/to key files (SSH key files, etc.), and also write them in other formats. SUPPORT Bugs should be reported via the CPAN bug tracker at For other issues, contact the author.

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 ---------------------------------------------------------------------------- The Artistic License Preamble The intent of this document is to state the conditions under which a Package may be copied, such that the Copyright Holder maintains some semblance of artistic control over the development of the package, while giving the users of the package the right to use and distribute the Package in a more-or-less customary fashion, plus the right to make reasonable modifications. Definitions: - "Package" refers to the collection of files distributed by the Copyright Holder, and derivatives of that collection of files created through textual modification. - "Standard Version" refers to such a Package if it has not been modified, or has been modified in accordance with the wishes of the Copyright Holder. - "Copyright Holder" is whoever is named in the copyright or copyrights for the package. - "You" is you, if you're thinking about copying or distributing this Package. - "Reasonable copying fee" is whatever you can justify on the basis of media cost, duplication charges, time of people involved, and so on. (You will not be required to justify it to the Copyright Holder, but only to the computing community at large as a market that must bear the fee.) - "Freely Available" means that no fee is charged for the item itself, though there may be fees involved in handling the item. It also means that recipients of the item may redistribute it under the same conditions they received it. 1. You may make and give away verbatim copies of the source form of the Standard Version of this Package without restriction, provided that you duplicate all of the original copyright notices and associated disclaimers. 2. You may apply bug fixes, portability fixes and other modifications derived from the Public Domain or from the Copyright Holder. A Package modified in such a way shall still be considered the Standard Version. 3. You may otherwise modify your copy of this Package in any way, provided that you insert a prominent notice in each changed file stating how and when you changed that file, and provided that you do at least ONE of the following: a) place your modifications in the Public Domain or otherwise make them Freely Available, such as by posting said modifications to Usenet or an equivalent medium, or placing the modifications on a major archive site such as ftp.uu.net, or by allowing the Copyright Holder to include your modifications in the Standard Version of the Package. b) use the modified Package only within your corporation or organization. c) rename any non-standard executables so the names do not conflict with standard executables, which must also be provided, and provide a separate manual page for each non-standard executable that clearly documents how it differs from the Standard Version. d) make other distribution arrangements with the Copyright Holder. 4. You may distribute the programs of this Package in object code or executable form, provided that you do at least ONE of the following: a) distribute a Standard Version of the executables and library files, together with instructions (in the manual page or equivalent) on where to get the Standard Version. b) accompany the distribution with the machine-readable source of the Package with your modifications. c) accompany any non-standard executables with their corresponding Standard Version executables, giving the non-standard executables non-standard names, and clearly documenting the differences in manual pages (or equivalent), together with instructions on where to get the Standard Version. d) make other distribution arrangements with the Copyright Holder. 5. You may charge a reasonable copying fee for any distribution of this Package. You may charge any fee you choose for support of this Package. You may not charge a fee for this Package itself. However, you may distribute this Package in aggregate with other (possibly commercial) programs as part of a larger (possibly commercial) software distribution provided that you do not advertise this Package as a product of your own. 6. The scripts and library files supplied as input to or produced as output from the programs of this Package do not automatically fall under the copyright of this Package, but belong to whomever generated them, and may be sold commercially, and may be aggregated with this Package. 7. C or perl subroutines supplied by you and linked into this Package shall not be considered part of this Package. 8. The name of the Copyright Holder may not be used to endorse or promote products derived from this software without specific prior written permission. 9. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.

Thanks to CFRANKS for the patch. - Makefile.PL update, to the latest Module::Install. Thanks to Adam Kennedy for the patch. 0.13 2005.05.26 - Rewrote to use Math::BigInt instead of Math::Pari, including patches from Brad Fitzpatrick for a replacement for the isprime function (both using pure Perl and an external gp program). - Added optional Content argument to Crypt::DSA::Key->new, to specify serialized Content to be deserialized. - Added Signature serialization and deserialization of ASN.1-encoded structures. - Added ability to do key generation using an external openssl binary. Thanks to Brad Fitzpatrick for the patch. - Signature object now has better get/set acccessors. - Use Module::Install instead of hand-coded Makefile.PL. 0.12 2001.05.03 - Removed swap file from the distribution. :) 0.11 2001.05.02 - Added Crypt::DSA::Key::SSH2, which reads SSH2-format DSA key files. These are a different format than those used by OpenSSH (that uses PEM-encoded files). Currently only reading SSH2 key files is supported, and the files must not be encrypted. - Added size method to Crypt::DSA::Key. $key->size is number of bits in p. 0.10 2001.04.22 - Added much better test suite: tests bigint utilities in Util, sign/verify, key generation (512, 768, 1024 bits), PEM encoding/decoding (if Convert::PEM is installed), FIPS 186-2 example case. - Added interface to Convert::PEM to read/write encrypted PEM files containing ASN.1-encoded DSA keys. Convert::PEM is optional; Makefile.PL will check for it and warn if it can't be found. - Get/set accessors now take hex values and store their values internally as strings. Thanks to Crypt::RSA for the idea. :) 0.03 2001.04.07 - abstracted signature object into Crypt::DSA::Signature object. 0.02 2001.03.23 - split up code into separate modules (ie. KeyChain, Key, Util, etc.) - switched from using GMP to Pari - streamlined code - added documentation 0.01 2001.03.22 - original version; created by h2xs 1.19 Crypt-DSA-1.17/inc/0000755000175100017510000000000011576531044012317 5ustar adamadamCrypt-DSA-1.17/inc/Module/0000755000175100017510000000000011576531044013544 5ustar adamadamCrypt-DSA-1.17/inc/Module/Install/0000755000175100017510000000000011576531044015152 5ustar adamadamCrypt-DSA-1.17/inc/Module/Install/Can.pm0000644000175100017510000000333311576531034016212 0ustar adamadam#line 1 package Module::Install::Can; use strict; use Config (); use File::Spec (); use ExtUtils::MakeMaker (); use Module::Install::Base (); use vars qw{$VERSION @ISA $ISCORE}; BEGIN { $VERSION = '1.01'; @ISA = 'Module::Install::Base'; $ISCORE = 1; } # check if we can load some module ### Upgrade this to not have to load the module if possible sub can_use { my ($self, $mod, $ver) = @_; $mod =~ s{::|\\}{/}g; $mod .= '.pm' unless $mod =~ /\.pm$/i; my $pkg = $mod; $pkg =~ s{/}{::}g; $pkg =~ s{\.pm$}{}i; local $@; eval { require $mod; $pkg->VERSION($ver || 0); 1 }; } # check if we can run some command sub can_run { my ($self, $cmd) = @_; my $_cmd = $cmd; return $_cmd if (-x $_cmd or $_cmd = MM->maybe_command($_cmd)); for my $dir ((split /$Config::Config{path_sep}/, $ENV{PATH}), '.') { next if $dir eq ''; my $abs = File::Spec->catfile($dir, $_[1]); return $abs if (-x $abs or $abs = MM->maybe_command($abs)); } return; } # can we locate a (the) C compiler sub can_cc { my $self = shift; my @chunks = split(/ /, $Config::Config{cc}) or return; # $Config{cc} may contain args; try to find out the program part while (@chunks) { return $self->can_run("@chunks") || (pop(@chunks), next); } return; } # Fix Cygwin bug on maybe_command(); if ( $^O eq 'cygwin' ) { require ExtUtils::MM_Cygwin; require ExtUtils::MM_Win32; if ( ! defined(&ExtUtils::MM_Cygwin::maybe_command) ) { *ExtUtils::MM_Cygwin::maybe_command = sub { my ($self, $file) = @_; if ($file =~ m{^/cygdrive/}i and ExtUtils::MM_Win32->can('maybe_command')) { ExtUtils::MM_Win32->maybe_command($file); } else { ExtUtils::MM_Unix->maybe_command($file); } } } } 1; __END__ #line 156 Crypt-DSA-1.17/inc/Module/Install/Base.pm0000644000175100017510000000214711576531034016365 0ustar adamadam#line 1 package Module::Install::Base; use strict 'vars'; use vars qw{$VERSION}; BEGIN { $VERSION = '1.01'; } # Suspend handler for "redefined" warnings BEGIN { my $w = $SIG{__WARN__}; $SIG{__WARN__} = sub { $w }; } #line 42 sub new { my $class = shift; unless ( defined &{"${class}::call"} ) { *{"${class}::call"} = sub { shift->_top->call(@_) }; } unless ( defined &{"${class}::load"} ) { *{"${class}::load"} = sub { shift->_top->load(@_) }; } bless { @_ }, $class; } #line 61 sub AUTOLOAD { local $@; my $func = eval { shift->_top->autoload } or return; goto &$func; } #line 75 sub _top { $_[0]->{_top}; } #line 90 sub admin { $_[0]->_top->{admin} or Module::Install::Base::FakeAdmin->new; } #line 106 sub is_admin { ! $_[0]->admin->isa('Module::Install::Base::FakeAdmin'); } sub DESTROY {} package Module::Install::Base::FakeAdmin; use vars qw{$VERSION}; BEGIN { $VERSION = $Module::Install::Base::VERSION; } my $fake; sub new { $fake ||= bless(\@_, $_[0]); } sub AUTOLOAD {} sub DESTROY {} # Restore warning handler BEGIN { $SIG{__WARN__} = $SIG{__WARN__}->(); } 1; #line 159 Crypt-DSA-1.17/inc/Module/Install/Fetch.pm0000644000175100017510000000462711576531034016551 0ustar adamadam#line 1 package Module::Install::Fetch; use strict; use Module::Install::Base (); use vars qw{$VERSION @ISA $ISCORE}; BEGIN { $VERSION = '1.01'; @ISA = 'Module::Install::Base'; $ISCORE = 1; } sub get_file { my ($self, %args) = @_; my ($scheme, $host, $path, $file) = $args{url} =~ m|^(\w+)://([^/]+)(.+)/(.+)| or return; if ( $scheme eq 'http' and ! eval { require LWP::Simple; 1 } ) { $args{url} = $args{ftp_url} or (warn("LWP support unavailable!\n"), return); ($scheme, $host, $path, $file) = $args{url} =~ m|^(\w+)://([^/]+)(.+)/(.+)| or return; } $|++; print "Fetching '$file' from $host...

The implementation itself is pure Perl, although the heavy-duty mathematics underneath are provided by the I library. This package provides DSA signing, signature verification, and key generation. =head1 USAGE The I public interface is similar to that of I. This was done intentionally. =head2 Crypt::DSA->new Constructs a new I object. At the moment this isn't particularly useful in itself, other than being the object you need to do much else in the system. Returns the new object. =head2 $key = $dsa->keygen(%arg) Generates a new set of DSA keys, including both the public and private portions of the key. I<%arg> can contain: =over 4 =item * Size The size in bits of the I

value to generate. The I and I values are always 160 bits each. This argument is mandatory. =item * Seed A seed with which I generation will begin. If this seed does not lead to a suitable prime, it will be discarded, and a new random seed chosen in its place, until a suitable prime can be found. This is entirely optional, and if not provided a random seed will be generated automatically. =item * Verbosity Should be either 0 or 1. A value of 1 will give you a progress meter during I

and I generation--this can be useful, since the process can be relatively long. The default is 0. =back =head2 $signature = $dsa->sign(%arg) Signs a message (or the digest of a message) using the private portion of the DSA key and returns the signature. The return value--the signature--is a I object. I<%arg> can include: =over 4 =item * Digest A digest to be signed. The digest should be 20 bytes in length or less. You must provide either this argument or I (see below). =item * Key The I object with which the signature will be generated. Should contain a private key attribute (I). This argument is required. =item * Message A plaintext message to be signed. If you provide this argument, I will first produce a SHA1 digest of the plaintext, then use that as the digest to sign. Thus writing my $sign = $dsa->sign(Message => $message, ... ); is a shorter way of writing use Digest::SHA1 qw( sha1 ); my $sig = $dsa->sign(Digest => sha1( $message ), ... ); =back =head2 $verified = $dsa->verify(%arg) Verifies a signature generated with I. Returns a true value on success and false on failure. I<%arg> can contain: =over 4 =item * Key Key of the signer of the message; a I object. The public portion of the key is used to verify the signature. This argument is required. =item * Signature The signature itself. Should be in the same format as returned from I, a I object. This argument is required. =item * Digest The original signed digest whose length is less than or equal to 20 bytes. Either this argument or I (see below) must be present. =item * Message As above in I, the plaintext message that was signed, a string of arbitrary length. A SHA1 digest of this message will be created and used in the verification process. =back =head1 TODO Add ability to munge format of keys. For example, read/write keys from/to key files (SSH key files, etc.), and also write them in other formats. =head1 SUPPORT Bugs should be reported via the CPAN bug tracker at L For other issues, contact the author. =head1 AUTHOR Benjamin Trott Eben@sixapart.comE =head1 COPYRIGHT Except where otherwise noted, Crypt::DSA is Copyright 2006 - 2011 Benjamin Trott.

Subclasses of I implement I and I methods, such that you can store DSA keys on disk, and read them back into your application. =head1 USAGE Any of the key attributes can be accessed through combination get/set methods. The key attributes are: I

, I, I, I, and I. For example: $key->p($p); my $p2 = $key->p; =head2 $key = Crypt::DSA::Key->new(%arg) Creates a new (empty) key object. All of the attributes are initialized to 0. Alternately, if you provide the I parameter (see below), the key will be read in from disk. If you provide the I parameter (mandatory if I is provided), be aware that your key will actually be blessed into a subclass of I. Specifically, it will be the class implementing the specific read functionality for that type, eg. I. Returns the key on success, C otherwise. (See I for one reason why I might return C). I<%arg> can contain: =over 4 =item * Type The type of file where the key is stored. Currently the only option is I, which indicates a PEM file (optionally encrypted, ASN.1-encoded object). Support for reading/writing PEM files comes from I; if you don't have this module installed, the I method will die. This argument is mandatory, I you're either reading the file from disk (ie. you provide a I argument) or you've specified the I argument. =item * Filename The location of the file from which you'd like to read the key. Requires a I argument so the decoder knows what type of file it is. You can't specify I and I at the same time. =item * Content The serialized version of the key. Requires a I argument so the decoder knows how to decode it. You can't specify I and I at the same time. =item * Password If your key file is encrypted, you'll need to supply a passphrase to decrypt it. You can do that here. If your passphrase is incorrect, I will return C. =back =head2 $key->write(%arg) Writes a key (optionally) to disk, using a format that you define with the I parameter. If your I<$key> object has a defined I (private key portion), the key will be written as a DSA private key object; otherwise, it will be written out as a public key. Note that not all serialization mechanisms can produce public keys in this version--currently, only PEM public keys are supported. I<%arg> can include: =over 4 =item * Type The type of file format that you wish to write. I is one example (in fact, currently, it's the only example). This argument is mandatory, I your I<$key> object is already blessed into a subclass (eg. I), and you wish to write the file using the same subclass. =item * Filename The location of the file on disk where you want the key file to be written. =item * Password If you want the key file to be encrypted, provide this argument, and the ASN.1-encoded string will be encrypted using the passphrase as a key. =back =head2 $key->size Returns the size of the key, in bits. This is actually the number of bits in the large prime I

It allows you to separately generate the I

, I, and I key parameters, given an optional starting seed, and a mandatory bit size for I

(I and I are 160 bits each). You can then call I to generate the public and private portions of the key. =head1 USAGE =head2 $keychain = Crypt::DSA::KeyChain->new Constructs a new I object. At the moment this isn't particularly useful in itself, other than being the object you need in order to call the other methods. Returns the new object. =head2 $key = $keychain->generate_params(%arg) Generates a set of DSA parameters: the I

, I, and I values of the key. This involves finding primes, and as such it can be a relatively long process. When invoked in scalar context, returns a new I object. In list context, returns the new I object, along with: the value of the internal counter when a suitable prime I

was found; the value of I when I was derived; and the value of the seed (a 20-byte string) when I was found. These values aren't particularly useful in normal circumstances, but they could be useful. I<%arg> can contain: =over 4 =item * Size The size in bits of the I

value to generate. The I and I values are always 160 bits each. This argument is mandatory. =item * Seed A seed with which I generation will begin. If this seed does not lead to a suitable prime, it will be discarded, and a new random seed chosen in its place, until a suitable prime can be found. This is entirely optional, and if not provided a random seed will be generated automatically. =item * Verbosity Should be either 0 or 1. A value of 1 will give you a progress meter during I

and I generation--this can be useful, since the process can be relatively long. The default is 0. =back =head2 $keychain->generate_keys($key) Generates the public and private portions of the key I<$key>, a I object. =head1 AUTHOR & COPYRIGHT Please see the L manpage for author, copyright, and license information. =cut Crypt-DSA-1.17/lib/Crypt/DSA/Signature.pm0000644000175100017510000000607511576531002016325 0ustar adamadampackage Crypt::DSA::Signature; use strict; use Carp qw( croak ); use vars qw{$VERSION}; BEGIN { $VERSION = '1.17'; } sub new { my $class = shift; my %param = @_; my $sig = bless { }, $class; if ($param{Content}) { return $sig->deserialize(%param); } $sig; } BEGIN { no strict 'refs'; for my $meth (qw( r s )) { *$meth = sub { my($key, $value) = @_; if (ref $value eq 'Math::Pari') { $key->{$meth} = Math::Pari::pari2pv($value); } elsif (ref $value) { $key->{$meth} = "$value"; } elsif ($value) { if ($value =~ /^0x/) { $key->{$meth} = Math::BigInt->new($value)->bstr; } else { $key->{$meth} = $value; } } my $ret = $key->{$meth} || ""; $ret = Math::BigInt->new("$ret") if $ret =~ /^\d+$/; $ret; }; } } sub asn { require Convert::ASN1; my $asn = Convert::ASN1->new; $asn->prepare('SEQUENCE { r INTEGER, s INTEGER }') or croak $asn->{error}; $asn; } sub deserialize { my $sig = shift; my %param = @_; my $asn = __PACKAGE__->asn; my $ref; require MIME::Base64; ## Turn off warnings, because we're attempting to base64-decode content ## that may not be base64-encoded. local $^W = 0; for ($param{Content}, MIME::Base64::decode_base64($param{Content})) { my $out = $asn->decode($_); $ref = $out, last if $out; } croak "Invalid Content" unless $ref; $sig->s($ref->{s}); $sig->r($ref->{r}); $sig; } sub serialize { my $sig = shift; my %param = @_; my $asn = __PACKAGE__->asn; my $buf = $asn->encode({ s => $sig->s, r => $sig->r }) or croak $asn->{error}; $buf; } 1; __END__ =head1 NAME Crypt::DSA::Signature - DSA signature object =head1 SYNOPSIS use Crypt::DSA::Signature; my $sig = Crypt::DSA::Signature->new; $sig->r($r); $sig->s($s); =head1 DESCRIPTION I represents a DSA signature.
