Does anyone use gmail + PGP ? if the two parties understand how to send encrypted messages over web clients, isn't that still secure ? I haven't heard much about PGP for the past 5+ years. I realize PGP itself isn't a protocol, but there used to be a system where you'd publish your public key (irrespective of what protocol (RSA, ECDSA, etc) you use) somewhere and anyone could send you encrypted messages and paste the base64 text into insecure clients.
