OpenPGP is the most widely-used e-mail encryption standard in the world. It is defined by the OpenPGP Working Group of the Internet Engineering Task Force (IETF) Proposed Standard RFC 4880. The OpenPGP standard was originally derived from PGP (Pretty Good Privacy), first created by Phil Zimmermann in 1991.

• Parses OpenPGP messages into their constituent packets.
  • Supports both old-format (PGP 2.6.x) and new-format (RFC 4880) packets.
• Helper class for verifying, signing, encrypting, and decrypting messages using Crypt_RSA from http://phpseclib.sourceforge.net
• Helper class for encrypting and decrypting messages and keys using Crypt_AES and Crypt_TripleDES from http://phpseclib.sourceforge.net
