I mentioned this module in a posting a couple of weeks ago, and several people expressed interest, so I thought I would make a small announcement. Hope that's not frowned upon. :)

Crypt::OpenPGP is a pure-Perl implementation of the OpenPGP standard. 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 digital signing/verification, encryption/decryption, keyring management, and key-pair generation.

Features:

  • Full compatibility with other PGP implementations: PGP2, PGP5, GnuPG. Offers a 'Compat' flag when encrypting and signing data that automatically chooses the correct encryption cipher, digest algorithm etc. for various other PGP implementations.
  • Encryption/decryption, signing/verification, key generation.
  • Symmetric cipher support: IDEA, 3DES, Blowfish, Twofish, Rijndael (128, 192, and 256 bit keys).
  • Public key support: RSA and DSA for signing/verification, RSA and ElGamal for encryption.
  • Digest algorithms: MD5, SHA-1, RIPE-MD/160.
  • Supports packet compression (ZIP and Zlib).
