Demo: A secure way to do encrypted email

Most encrypted emails system claim to be secure since they leverage an external key store to hold the keys that were used to encrypt and decrypt the email. The problem is, when the message needs to be displayed, the ‘server’ needs to ask the external key store for the decryption key; which means that while the server doesn’t store the key locally, it can still get it.
