[Announce] New version of Systemics crypto library for Perl
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
