NIST vs SECP

[mcr]

 nistp256.rb             
 secp256r1.rb   

As far as I can verify, these are two names for the same group.
Ditto for the 192 and 521.

no longer answers, being directed to certicom's web site. I wonder if it wouldn't be better to just have one or the other in the source code base?

Thanks for pointing this out. I can't think of any particular changes I would want to make to the code in light of this information which would not be breaking changes. Even just making one group be an alias for the other would be a breaking change because param_a and name of one of the groups would have to change.

Okay, reasonable.
