Perl extension implementing one way hash chaining encryption using MD5
This module implements a chaining block cipher using a one
way hash. This method of encryption is the same that is
used by radius (RFC2138) and is also described in Applied
Cryptography.
Two interfaces are provided in the module. The first is
straight block encryption/decryption the second does base64
mime encoding/decoding of the encrypted/decrypted blocks.
The idea is the two sides have a shared secret that
supplies one of the keys and a randomly generated block of
bytes provides the second key. The random key is passed in
cleartext between the two sides.
An example client and server are packaged as modules with
this module. They are used in the tests.

Perl implementation of the NULL encryption algorithm
This is Crypt::NULL. Perl module for NULL Encryption Algorithm.
The NULL Encryption Algorithm is a symmetric block cipher described in
RFC 2410 by Rob Glenn and Stephen Kent.
This module implements NULL encryption. It supports the Crypt::CBC.
Perl extension for OpenSSL EC (Elliptic Curves) library
This module provides a standard (non-OO) interface to the OpenSSL EC (Elliptic
Curve) library. Some OO Calls are supported.
Most of the functions described in openssl/ec.h are supported.
Perl extension for Loki97 block cipher
Loki97 is 128-bit block cipher that accepts a variable-length key. It was
designed by Lawrie Brown, Josef Pieprzyk, and Jennifer Seberry. The default
key length in this implementation is 128 bits. Loki97 was one of the 15
candidates for the AES.
Perl5 module to RSA encode and decode strings using OpenSSL
Crypt::OpenSSL::RSA provides the ability to RSA encrypt
strings which are somewhat shorter than the block size of
a key. It also allows for decryption, signatures and
signature verification.
Perl implementation of Rijndael
This is a pure perl implementation of the new AES Rijndael. You want
to use Crypt::Rijndael where available. This implementation is really
slow, but I am working on it.
wrapper to the Digest::MD5 module
The current MD5 module is just a wrapper around the Digest::MD5
module. It is provided so that legacy code that rely on the old
interface still work and get the speed benefit of the new module.
Perl extension for D.J Bernstein's hash algorithm
Digest::DJB is an implementation of D. J. Bernstein's hash which returns a
32-bit unsigned value for any variable-length input string. An equivalent pure
Perl version is also available: Digest::DJB::PurePerl.
Source filter for Cipher Block Chaining
Filter::CBC is a Source filter that uses Cipher Block Chaining (CBC) to
encrypt your code. The tricky part is that most CBC Algorithms have binary
output. The textmode bypasses this obstacle, by converting the data to less
scary data.
