Dear OpenSSL-Users, recently i found a pitfall using EC_KEY_get0_public_key(key->pkey.ec). The function just returns a copy to a pointer to key->pub_key which is a EC_POINT pointer. The key itself is taken from a certificate using EVP_PKEY *key = X509_get_pubkey(cert); Fine, i assumed, these must be coordinates of the publich key in the elements X and Y! Both are BIGNUMS as expected. BUT instead i got some tranformed coordinates. Finally i got the coordinates by using EC_POINT_point2hex() with the propoer group and converting its output. There seems to be no instantly accessible BIGNUM-pair represesentation of a ECDSA public key, which i would like to gain access to. What am i missing? Thanks in advance -- Chris
