Hi dear fellows,

I would like to know if there is any function(s) in OpenSSL that handles public key validation for ECDSA.

Given a point (public key) and a curve, I would like to test if this point is a valid public key for this curve.

have a look at EC_KEY_check_key() in crypto/ec/ec_key.c

Cheers,
Nils
