Comment (by warner):

 Also see https://github.com/agl/curve25519-donna , which includes a python
 binding (that I wrote). The {{{PublicKey}}}/{{{PrivateKey}}} objects might
 make a nice API, or maybe there's some Crypto++ pattern that we should
 stick to. It's worth remembering that Curve25519 only offers DH key
 agreement (the output is a 256-bit shared random key). You can build
 public-key encryption on top of that, though (by creating a random keypair
 for each encryption, and including the public half along with the
 encrypted message, then discarding the private half).
