CertComparePublicKeyInfo function

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

Syntax

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

Parameters

dwCertEncodingType [in]

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

pPublicKey1 [in]

A pointer to the CERT_PUBLIC_KEY_INFO for the first public key in the comparison.

pPublicKey2 [in]

A pointer to the CERT_PUBLIC_KEY_INFO for the second public key in the comparison.

Return value

If the public keys are identical and the function succeeds, the function returns nonzero (TRUE).

If the function fails, it returns zero (FALSE).
