Description:

*Crypt::OpenPGP* is a pure-Perl implementation of the OpenPGP
standard[1]. In addition to support for the standard itself,
*Crypt::OpenPGP* claims compatibility with many other PGP implementations,
both those that support the standard and those that preceded it.

*Crypt::OpenPGP* provides signing/verification, encryption/decryption,
keyring management, and key-pair generation; in short it should provide
you with everything you need to PGP-enable yourself. Alternatively it
can be used as part of a larger system; for example, perhaps you have
a web-form-to-email generator written in Perl, and you'd like to encrypt
outgoing messages, because they contain sensitive information.
*Crypt::OpenPGP* can be plugged into such a scenario, given your public
key, and told to encrypt all messages; they will then be readable only
by you.

This module currently supports "RSA" and "DSA" for digital signatures,
and "RSA" and "ElGamal" for encryption/decryption. It supports the
symmetric ciphers "3DES", "Blowfish", "IDEA", "Twofish", "CAST5", and
"Rijndael" ("AES"). "Rijndael" is supported for key sizes of 128,
192, and 256 bits. *Crypt::OpenPGP* supports the digest algorithms
"MD5", "SHA-1", and "RIPE-MD/160". And it supports "ZIP" and "Zlib"
compression.
