This function acquires the bit length of public/private keys from a public key BLOB.

Syntax

DWORD WINAPI CertGetPublicKeyLength(
  DWORD dwCertEncodingType,
  PCERT_PUBLIC_KEY_INFO pPublicKey
);

Parameters

  • dwCertEncodingType
    [in] Specifies the encoding type used. Only X509_ASN_ENCODING is used.
  • pPublicKey
    [in] Pointer to the public key BLOB containing the keys for which the length is being retrieved.

Return Value

Returns the length of the public/private keys in bits. If unable to determine the key's length, returns zero.

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