Installation

yum --enablerepo=remi  install  thunderbird-enigmail

This extension is, for me, an essential Thunderbird partner, it provides a full OpenPGP key management system and the tools needed to sign, verify, encrypt and decrypt messages.

When you send a "physical" message, you choose an envelope or a post card, or even send it by registered post, according to the content and expected privacy. You could consider OpenPGP as a virtual envelope.

With the current big attack against our private life, I think it is really urgent that we all use this tools.
