Thanks for that explanation - so, just to understand the history, why is there
no secp256_r1 as well as the ANSI standard curve. In other words, why does the
ANSI curve replace it instead of being an additional curve?
http://tools.ietf.org/html/draft-ietf-pkix-ecc-nist-recommended-curves-00
defined the extra NIST recommended curves. The secp256_r1 (and secp192r1) were
already defined in the ANSI X9.63, so the existing OIDs were used.
I have no idea :-) It is one of lifes mysteries!
