What do you mean "do not match"? ECDSA uses a random value during signature generation so signing the same data with the same key is highly unlikely to produce the same signature. You should however be able to verify one signature using the other implementation. Steve. -- Dr Stephen N. Henson. OpenSSL project core developer.
