openpgp (hackage): This is an OpenPGP library inspired by my work on OpenPGP libraries in Ruby https://github.com/singpolyma/openpgp, PHP http://github.com/singpolyma/openpgp-php, and Python https://github.com/singpolyma/OpenPGP-Python.  It defines types to represent OpenPGP messages as a series of packets and then defines instances of Data.Binary for each to facilitate encoding/decoding.  For performing cryptography, see http://hackage.haskell.org/package/openpgp-crypto-api or http://hackage.haskell.org/package/openpgp-Crypto  For dealing with ASCII armor, see http://hackage.haskell.org/package/openpgp-asciiarmor  It is intended that you use qualified imports with this library.
