[Cryptography-dev] Elliptic Curve Documentation

Well, ECDH is just a way to establish a shared secret. You will have to
implement the encryption method yourself.

When you say ECDH, I'm going to assume you mean plain ECDH while ECDHE
(ephemeral) is what you're really going to want to use due to its security
features (forward secrecy, etc).

With that said, there is a hazmat primitive for ECDH, but I would strongly
recommend that you figure out how you would implement ECDHE with it before
you try to build anything. This primitive is:
`cryptography.hazmat.primitives.asymmetric.ec.ECDH`.

>From that, you'll get a shared secret that you can use.

Coming from Java and BouncyCastle, I'm having trouble learning how to
implement EC using Cryptography. Is there a comprehensive tutorial anywhere?
The issue I am trying to resolve is how to implement ECDH and encrypt the
text of a message.
