Hello!
I have ECC certificate:
///
Subject Public Key Info:
Public Key Algorithm: id-ecPublicKey
EC Public Key:
pub:
04:e0:fd:c3:07:be:0e:db:35:9c:05:c8:d7:82:36:

and signed hash, with smart card private key. Some commercial soft validate
signature correctly.
If I try use openssl:
///
ERR_load_EC_strings();
X509 *x = NULL; int type = 0; EVP_PKEY *key = NULL; int len = 0; EC_KEY *ec
= NULL; int ret = 0; char *er;
d2i_X509(&x, (const unsigned char**)&pCert->pbCertEncoded,
pCert->cbCertEncoded);
key = X509_PUBKEY_get(x->cert_info->key);
ec = EVP_PKEY_get1_EC_KEY(key);
if(ec){
ret = ECDSA_verify(0,pbyHash,dwHashLen,pbSignature,dwSigLen,ec);
er = ERR_error_string(ERR_get_error(),NULL);
}
///
I have error "error:0D07209B:asn1 encoding routines:func(114):reason(155)"
:confused:
Hash - SHA1, dwHashLen = 20, dwSigLen = 48.
What is wrong?
