PGP

The Pretty Good Privacy package from Zimmermann.

PGP lets you sign and encrypt messages using public keys. There is considerable documentation that comes with PGP itself. PGP is to an email message what an envelope is to a letter.

Exmh allows to conveniently use PGP to encrypt or sign your messages and decrypt and check signatures on messages you receive.

To start using PGP, you have to create a key pair. A key pair consists of a public key (that you want to spread around) and a private key (that you don't want anybody else than yourself to have).

The private key is protected by a password. You should be *very* careful not to lose that password *and* not to let anybody get access to it. PGP can offer a very high level of security, but if people can read your file (especially the file that contains the private key) and can find your password (reading keystrokes is very easy once you have access to the Xserver) then all the great work put into the encryption algorithm is totally useless :-)

This button will run PGP to create a key pair. It will create a directory where PGP keys will be kept (by default ~/.pgp), make a key pair (this can be fairly time consuming), sign the key (you should read the PGP documentation to find out why this is done. It doesn't explain why it isn't automatically done by PGP, tho :-( ) and finally will send the public key to the keyserver so that other people can find it (in case they want to send you encrypted mail or if they want to check some signature of yours).

You must restart exmh after creating your public key. By default, exmh does not display any PGP-related menus if you are not yet set up for PGP.
