>> Has anyone here tried to implement [draft-green-secsh-ecc]?
I'd like to, but it appears unimplementable without copies of X9.63
and IEEE1363, [...]
ANSI X9.63 and IEEE 1363 are listed as informative references only.
I believe that SEC 1, listed as a normative reference, contains all
information required to implement ECDH, ECDSA, and ECMQV; it is
freely available from the URL in the references.
Actually, it is not; it is at least two and I think three links removed
from the URL in the references. (The shortest path I've found is
http://www.secg.org/ -> "Documents" ->
http://www.secg.org/index.php?action=secg,docs_home -> "Released
Standards" -> http://www.secg.org/?action=secg,docs_secg -> "SEC1:
Elliptic Curve Cryptography version 2.0" ->
http://www.secg.org/download/aid-780/sec1-v2.pdf.)
