Review for Enigmail by AviHD
Rated 5 out of 5 stars
Cake to setup with the undaunted User Guide. This should usher in a new era of PGP which was impossible to teach non-Outlook users to. I know I'm gonna try to at least show some mates who wouldn't dream of it but might like to try it now.
TO NEW USERS: I've always misplaced keys and PGP public keys cannot be deleted. Enigmail's easy key-wizard saves a revocation certificate.
ALWAYS having a backup of this eases key management. Get one of those free online backup accounts, like DropBox and store the revocation key there.
