I read the public ECKEY in shown below from the x509
x509= PEM_read_bio_X509(bio,NULL, 0, NULL); //its public there is no
password
EVP_PKEY *evpkey = X509_get_pubkey(x509);
pubeckey= EVP_PKEY_get1_EC_KEY(evpkey);
BIO_free(bio);
//But do I need this setting the curvetype???
//Will it know the curve type
EC_GROUP *curve= EC_GROUP_new_by_curve_name(curvetype);
int ret= EC_KEY_set_group(pubeckey,curve);
//I use this to verify the signature
int rc = ECDSA_verify(0, result, SHA256_DIGEST_LENGTH, signature.bytes,
signature.length, pubeckey);
