Key generation just uses the lower level EC routines.i.e.
EC_KEY_generate_key()
EC(DH/DSA) isn't quite the same as DH/DSA.

Sorry , I can't help with leaving bits out - there's quite a bit you do
need.

Hi !

I would to know how to generate a key with the ECDSA algorithm from openssl
or do I have to use the ECDH algorithm for that?

If I have to use ECDH, how do I generate a key ?  ECDH is only to share a
secret key.

An other question: I am doing cryptograhy with EDCSA an/or ECDH I would
like
to use less code lines from openssl as possible. What should I keep or
leave
from the code.

Thanks! Hope you will understant my question.
