Crypt/GeneratePassword version 0.02 =================================== This module lets you generate secure random passwords with a reasonable amount of pronounceability. It avoids the problems associated with the FIPS-181 NIST standard as used by Crypt::RandPasswd. See perldoc for more details.

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.

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.

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.

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.

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.

A simple implementation of the RC4 algorithm, developed by RSA Security, Inc. Here is the description from RSA's website: RC4 is a stream cipher designed by Rivest for RSA Data Security (now RSA Security). It is a variable key-size stream cipher with byte-oriented operations. The algorithm is based on the use of a random permutation. Analysis shows that the period of the cipher is overwhelmingly likely to be greater than 10100. Eight to sixteen machine operations are required per output byte, and the cipher can be expected to run very quickly in software. Independent analysts have scrutinized the algorithm and it is considered secure. Based substantially on the "RC4 in 3 lines of perl" found at http://www.cypherspace.org Seamus Venasse <svenasse@polaris.ca>

The axTLS project is an SSL client/server library using the TLSv1 protocol. It is designed to be small and fast, and is suited to embedded projects. A web server is included.

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.
