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

Syntax

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

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.

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

If the function fails, the return value is zero, or FALSE.

The desktop operating system supports the flag PKCS_7_ASN_ENCODING, but Windows Embedded CE does not and ignores the flag when it is specified.
