GPGMail

GPGMail Publisher's Description:
GPGMail is a plug-in for Apple's Mail, providing a front-end to gpg for some operations.

GPGMail extends Apple's Mail application and allows you to read and send authenticated and/or encrypted messages. You can use PGP for plain text and MIME messages, following RFC 3156. GPGMail sources are available.

What's new in this version:

* Added support for Tiger (10.4)
* Fixed invalid display of keys being revoked/expired/disabled/invalid
* Fixed compatibility problem with Windows' EudoraGPG

* Added retrieval of people gpg options from their AddressBook card (set by Robert Goldsmith's ABKey bundle)
* No longer tries to use invalid secret key when encrypting
* Got rid of GPGMEProxyServer
* Much faster PGP operations, notably key listing
* When a draft is restored, the encryption and signature states are restored too
* Fixed problem with attachments having non-ASCII filenames: now these chars are replaced by '_', but that doesn't affect final filename, except maybe on old mail clients.
* Fixed bug with default private key which needed to be selected manually to get actually selected
* Lot of new options
* Added PGP-settings conflict resolution panel on delivery
* Now correctly recognizes revoked/disabled keys
* No longer reports wrongly a hash algo choice error instead of the unability to sign
