Freenigma is an ingenious little Firefox plugin that simplifies the social networking aspect of public key cryptography. At this point, Gmail, Hotmail, and Yahoo Mail are supported. Here is how it works. First, type your email as usual:

Then, hit encrypt to get a PGP encoded message.

The recipient hits “decrypt,” and that’s it. Freenigma is not a substitute for end-to-end encrypted communication, for example, the To: and From: fields of the email are still plaintext. But for the occasional sensitive message, Freenigma is a great, minimally intrusive solution.
