GPL Secret Agent stores your secrets in a secure manner. Its main use at the moment is with GnuPG (an e-mail encryption/signation solution compatible to OpenPGP), or PGP 2.6. You can store your passphrase with Secret Agent, and have it provide that passphrase to GnuPG or PGP everytime it is needed. Happy New Year, Cristian
