How does secure e-mail work?

You can use secure e-mail to do the following:

Digitally sign a message so that the recipient can verify the message came from you and not an impostor. Signing a message also ensures the integrity of the message. That is, it ensures that no one tampered with the message.

Encrypt a message so that no one can read it while it travels from your computer to another.

You can set up most e-mail applications to automatically sign or encrypt your messages or you can manually choose to do it on a case-by-case basis.
