libsimplepgp is a library for loading PGP keys and decrypting PGP messages.

Instead of aiming to support the entire OpenPGP standard, as GnuPG does, this 
project aims to support only the most common PGP message formats used for 
encrypting e-mail messages.  

Initial goals are:
 * Parse secret and public keys
 * Store secret keys in an in-memory keychain
 * Decrypt message formats commonly found in e-mail communication:
   - DSA/Elgamal and RSA asymmetric keys
   - TripleDES, CAST5, and AES-256 symmetric ciphers
   - SHA-1 hashes
   - ZIP and ZLIB compression
 * Support PC (UNIX-ish) platforms
 * Support iOS (iPhone) platforms
   
Known limitations:
 * No support for creating messages (encryption)
 * No support for validating signatures
 * No support for old formats, or deprecated message types
 * Not thread-safe
