In my humble opinion, this has been an enormous limitation on this standard. But there are other curves with OIDs (check for the "Brainpool standard Curves". The rfc4492, similar to what you mention but for TLS, allows any arbitrary curve (prime & char2) but rfc 6637 doesn't allow us to go that far

Support for additional ECC Curves in GnuPG (gcrypt)

Hi Everyone, Do you know if someone is currently working to implement additional curves in ECC and especially to have an alternative to the NIST ones in gcrypt/GnuPG? and I was wondering if we are bound to the ones defined in: http://tools.ietf.org/html/rfc6637#section-11 Thank you, Cheers. -
