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. feedback and ok markus@
