Hi all,
I am trying to verify PKCS7 signature in C. I am use PKCS_signatureVerify(). However, an error is occured.
The error:
"140736204891696:error:21071065:PKCS7 routines:PKCS7_signatureVerify:digest failure:pk7_doit.c:1106"
The source:
...
BIO * p7Bio = NULL;
//Signer certificate
X509 * certificate = ...
p7Bio=PKCS7_dataInit(pkcs7,NULL);
//Fetch signer info from pkcs7
STACK_OF(PKCS7_SIGNER_INFO) * signerInfoStack = PKCS7_get_signer_info(pkcs7);
int numberOfSignerInfo = sk_PKCS7_SIGNER_INFO_num(signerInfoStack);
for (int i=0; i<numberOfSignerInfo; ++i)
{
PKCS7_SIGNER_INFO * signerInfo = sk_PKCS7_SIGNER_INFO_value(signerInfoStack, i);
int verificationResult = PKCS7_signatureVerify(p7Bio, pkcs7, signerInfo, certificate);
}
...
Anyone have advice on how to solve verification problem?
