Netpgp
netpgp is a BSD licensed project based on the OpenPGP SDK which provides signing, verification, encryption, and decryption of files.  It also comes with the netpgpkeys tool for key management.  Netpgp is a higher level wrapper and improvement upon the OpenPGP SDK library written by Ben Laurie and Rachel Willmer.  The public api of OpenPGP SDK is hidden exposing a simple interface for encryption and decryption as well as generating and verifying digital signatures.

netpgp was included in the NetBSD distribution on May 2009 and in MidnightBSD on June 2009.
