CertComparePublicKeyInfo

  • Article

This function compares two encoded public keys to determine whether they are identical.

BOOL WINAPI CertComparePublicKeyInfo(
DWORD dwCertEncodingType,
PCERT_PUBLIC_KEY_INFO pPublicKey1,
PCERT_PUBLIC_KEY_INFO pPublicKey2
);

Parameters

  • dwCertEncodingType
    [in] Specifies the encoding type used. Currently, only X509_ASN_ENCODING is used; however, additional encoding types may be added in the future.
  • pPublicKey1
    [in] Pointer to the CERT_PUBLIC_KEY_INFO structure for the first public key in the comparison.
  • pPublicKey2
    [in] Pointer to the CERT_PUBLIC_KEY_INFO structure for the second public key in the comparison.

Returned Values

If the public keys are identical and the function succeeds, the return value is nonzero (TRUE).

If the function fails, the return value is zero (FALSE).

Remarks

The desktop platform supports the PKCS_7_ASN_ENCODING flag, but Windows CE does not. Windows CE ignores the flag when it is specified.
