Evolution is an outstanding groupware suite with one of the finest email clients in all of Linux-land. For many users the standard email setup is great. It does everything they need: it sends and receives email (even HTML email if you so desire). But for others a little extra is needed…especially in the form of security. One way to secure your emails is to add a layer of encryption to them. This can be in the form of a simple signature or as much as a fully signed and encrypted email. Believe it or not, this is quite simple with the Evolution email client.

In this article I am going to show you how to take your encryption key and add it to your outgoing mail with Evolution. I will show you how to set up both signing and encrypting of email.
