PGP for Mac Mail

Listen to this articleListen to this article

If you've ever needed (perhaps need is too strong a word, how about wanted) to digitally sign—or encrypt for that matter—your emails from within the Mac Mail client, it's pretty simple. Even though there are plenty of mail applications that support PGP, I've grown fond of Mail.app so this morning—for no real good reason—I installed a few plugins, etc. and was up and running in literally 5 mins (ok 10 mins—I didn't have a clue what kind of signature I should use).

First go and get GPGMail. The download is a .DMG file and the instructions on the web site are easy to follow. In addition to GPGMail, you'll also need GNU PG for the Mac (GPGMac and GPG Keychain Access as a minimum).

I also found I needed to go into the Preferences>PGP>Composing and switch on "By default, use OpenPGP/MIME". This allows signed messages to be sent using MIME rather than the old-school format which surrounds the text in the signature and makes it look as though your email was sent through some kind of full-on nerdifier—a bit scary for mum.

Now that I have the ability to sign emails I'll just, well, probably never use it really—quite frankly, I can't imagine anyone being bothered to impersonate me in an email—but at least I feel "safer" LOL.

So anyway, here is my PGP key (valid until August 22, 2006) for anyone who cares:

Of course it occurs to me that someone could also spoof my blog and change the public key here but again, I'm thinking people have better things to waste their valuable time on like say, RAD for example ;-).

Hi,

With Leopard, this "Plug-In" doesn't work. It is disabled. (Leopard (MacOsX 10.5) uses Mail 3.x)
Has anyone a working GPG with Mail 3 on Leopard?
