  • Article

The CryptXmlGetAlgorithmInfo function decodes the CRYPT_XML_ALGORITHM structure and returns information about the algorithm.

Syntax

HRESULT CryptXmlGetAlgorithmInfo(
  [in]  const CRYPT_XML_ALGORITHM *pXmlAlgorithm,
        DWORD                     dwFlags,
  [out] CRYPT_XML_ALGORITHM_INFO  **ppAlgInfo
);

Parameters

[in] pXmlAlgorithm

A pointer to a CRYPT_XML_ALGORITHM structure that specifies the algorithm about which to return information.

dwFlags

This parameter can be one of the following values.

Value Meaning
CRYPT_XML_FLAG_DISABLE_EXTENSIONS
0x10000000
