Rexdude writes: PGP has been around for decades — there are digital signature/encryption plugins available for email and messenger clients, but I'm yet to see anyone using them normally outside of big companies. For example, Lotus Notes transparently supports certificates and encryption — you can set it up to encrypt mail by default and it's totally transparent to everyone within the organization. Yet I've never seen this happen for private use. There are PGP and OpenPGP plugins for everything from Thunderbird to Jabber clients, and now even on Android there's ChatSecure. But apart from a couple of fellow geeks, nobody's interested.
