Given your private key and somebody else's public key, this compute a (256 bit) shared secret.

This is actually very simple: since pubkey = G * privkey, the shared secret will be simply G * privkey1 * privkey2.

This can fail if for example an invalid pubkey is given, and in some other special circumstances.
