The Systemics Cryptix crypto library for Perl is now available for download at http://www.systemics.com/software/ Apart from much tidying up, there have been several signigicant additions to the library, include a Blowfish implementation, RSA encryption (including key generation routines), CFB and CBC block cipher mode modules, and a cryptographically secure random stream generator. This library is not currently on CPAN, since several modules are not in a suitable state for CPAN distribution. However, if anyone can rectify this, then we are happy to place them on CPAN. Enjoy! P.S. - PGP library on it's way soon (hopefully this weekend!) CRYPTIX LIBRARY FOR PERL (V1.1) _________________________________________________________________ Description This library contains a suite of cryptographic and mathematical modules for Perl. Many of the more CPU intensive algorithms have been implemented in C as Perl extensions. Features Perl extensions All of the following have been implemented as Perl extensions in C: * Crypt::Blowfish module (Blowfish implementation by A.M. Kuchling). * Crypt::DES module (DES implementation by Eric Young). * Crypt::IDEA module. * Crypt::MD5 module (based on an implementation by Neil Winton and Data Security, Inc.) * Crypt::SHA module (based on an implementation by Uwe Hollerbach and based on code from NIST and Peter C. Gutmann) * Math::BigInteger module (based on code from Eric Young). This module implements arbitrary length integers and some associated mathematical functions. * Math::PRSG - Pseudo random sequence generator This module implements a 160 bit LFSR for use in generating pseudo random sequences. * Math::TrulyRandom module, based on code from Don Mitchell and Matt Blaze (AT&T). This module generates "truly random" numbers, based on interrupt timing discrepancies. Perl modules All of the following have been implemented in Perl: * Crypt::CBC module This module implements CBC block cipher mode. * Crypt::CFB module This module implements CFB block cipher mode. * Crypt::CSRandomStream module This module implements a cryptographically secure random stream. It implements the Stream::DataInput interface. * Crypt::DES3EDE module This module implements triple DES (EDE mode). * Crypt::HashMD5 This module implements an MD5 hash, which derives from Crypt::MessageDigest. * Crypt::HashSHA This module implements an SHA hash, which derives from Crypt::MessageDigest. * Crypt::MessageDigest This module implements the Crypt::MessageDigest base class. * Crypt::RSAKey This module implements the RSA key base class. * Crypt::RSAKeyGen This module is used for the generation of RSA key pairs. * Crypt::RSAPublicKey This module implements an RSA public key, which derives from Crypt::RSAKey. * Crypt::RSASecretKeyPair This module implements an RSA public/secret key pair, which derives from Crypt::RSAKey. * Math::MPI module This module implements the reading and writing of Philip Zimmermans MPI format large integers. * Math::PseudoRandomStream module This module implements a pseudo random data stream. It implements the Stream::DataInput interface. * Math::Random module This module contains a collection of various random number routines. * Math::TestPrime module This module is used to test the primality of an instance of Math::BigInteger. * Stream::DataEncoding * Stream::DataInput * Stream::DataOutput * Stream::FileInput * Stream::FileOutput * Stream::Streamable * Stream::StringInput * Stream::StringOutput Copyright This library includes (or is derived from) software developed by (and owned by) the following: * Peter C.
