Re: @AC - How To Do Encryption IN THE REAL WORLD
PKI was invented to distribute symetric encryption keys over an insecure channel. The problem with PKI's is that everyone needs to use the same one (though bridging is possible). Both national governments and financial instututions wisely see no net benefit to prioviding large scale PKI's, so they are fragmented. You also need to trust the PKI to correctly distribute the public key. It gets really messy when you start factoring in key expiry and revocation and people forgetting their private key. These complications have limited it to small scale deployment, and this hasn't improved in the last 20 years.
