Yeah, similar in concept. You encrypt a message with a public key and can only decrypt it with the private key. It's great for storing data so that a root/filesystem compromise won't reveal any of the previously encrypted data. I'm hoping that jedisct1 will add a parallel functionality to libsodium soon. :) https://github.com/jedisct1/libsodium/issues/231 https://github.com/jedisct1/libsodium/issues/231

Parallelism is always a good thing. The specific similarity with PGP that jumped to mind is that you're not actually using your key (or recipients key) to encrypt the message. You're actually generating a random session key to encrypt the message contents and then you're encrypting the session key against the recipients key and sending them that. I was really taken by surprise the first time I read that, but after playing some more with crypto "obviously" you'd have to -otherwise what happens when your message is longer than your key?
