kuvert

wrapper that encrypts or signs outgoing mail

kuvert automatically signs and/or encrypts outgoing mail using the PGP/MIME standard (RFC3156), based on the availability of the recipient's key in your keyring. Other than similar wrappers, kuvert does not store key passphrases itself, ever. kuvert works as a wrapper around your MTA but can be fed mails via SMTP, too.
