curve25519-donna 1.3

Curve25519 is a fast elliptic-curve key-agreement protocol, in which two parties Alice and Bob each generate a (public,private) keypair, exchange public keys, and can then compute the same shared key. Specifically, Alice computes F(Aprivate, Bpublic), Bob computes F(Bprivate, Apublic), and both get the same value (and nobody else can guess that shared value, even if they know Apublic and Bpublic).

This is a Python wrapper for the portable ‘curve25519-donna’ implementation of this algorithm, written by Adam Langley, hosted at http://code.google.com/p/curve25519-donna/
