GPG: Encrypting messages in Apple Mail

GPGMailGPGMail is a plug-in that enables the sending and receiving of encrypted emails in Apple Mail. It works in Tiger and Panther, and acts as a front-end to macgpg, the Mac port of an open source encryption engine, gpg. You will need to install macgpg first.

After installing GPGMail, you will find a new sub-menu under the Message menu, from which you can manage your digital signatures and other encryption options. The developer’s website provides a list of the plug-in’s limitations, including the fact that encrypted messages are just stored by Apple Mail and not indexed.

It is freeware and is available from the developer’s website.

Joar Winfors provides some background on his site about using digital signatures in Apple Mail.

UPDATE: GPGMail 1.1.2 released, 5 February 2006.

UPDATE: 25 July 2011 The GPGTools web site now hosts this plug-in.

    I had to uninstall this plugin because Mail.app kept marking my read mail as unread with it installed.

    Unfortunately it doesn’t work at all with Mac OS 10.4.9 – plugin is disabled automaticaly by apple-mail during its startup – some compatibility problem.

    New article about GPGTools?
    Since people still read this blog entry to go download GPGMail, an update might be nice ;) The page http://gpgtools.org is hosting all related GPG tools for OS X now.
