     Implement Elliptic Curve Cryptography modes for key exchange (ECDH) and
     host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA offer
     better performance than plain DH and DSA at the same equivalent symmetric
     key length, as well as much shorter keys.

     Only the mandatory sections of RFC5656 are implemented, specifically the
     three REQUIRED curves nistp256, nistp384 and nistp521 and only ECDH and
     ECDSA. Point compression (optional in RFC5656 is NOT implemented).

     Certificate host and user keys using the new ECDSA key types are supported.

     Note that this code has not been tested for interoperability and may be
     subject to change.
