CertCompareCertificate function (wincrypt.h)
The CertCompareCertificate function determines whether two certificates are identical by comparing the issuer name and serial number of the certificates.
Syntax
BOOL CertCompareCertificate(
[in] DWORD dwCertEncodingType,
[in] PCERT_INFO pCertId1,
[in] PCERT_INFO pCertId2
);
Parameters
[in] dwCertEncodingType
Specifies the encoding type used. It is always acceptable to specify both the certificate and message encoding types by combining them with a bitwise-OR operation as shown in the following example:
X509_ASN_ENCODING | PKCS_7_ASN_ENCODING Currently defined encoding types are:
- X509_ASN_ENCODING
- PKCS_7_ASN_ENCODING
[in] pCertId1
A pointer to the CERT_INFO for the first certificate in the comparison.
[in] pCertId2
A pointer to the CERT_INFO for the second certificate in the comparison.
Return value
If the certificates are identical and the function succeeds, the function returns nonzero (TRUE).
If the function fails, it returns zero (FALSE).
