CryptXmlDllEncodeAlgorithm callback function (cryptxml.h)

  • Article

The CryptXmlDllEncodeAlgorithm function encodes SignatureMethod or DigestMethod elements for agile algorithms with default parameters.

The CryptXmlDllEncodeAlgorithm function is exposed through the exported CryptXmlDllGetInterface function.

Syntax

CryptXmlDllEncodeAlgorithm Cryptxmldllencodealgorithm;

HRESULT Cryptxmldllencodealgorithm(
  [in]      const CRYPT_XML_ALGORITHM_INFO *pAlgInfo,
            CRYPT_XML_CHARSET dwCharset,
  [in, out] void *pvCallbackState,
  [in]      PFN_CRYPT_XML_WRITE_CALLBACK pfnWrite
)
{...}

Parameters

[in] pAlgInfo

A pointer to a CRYPT_XML_ALGORITHM_INFO structure.

dwCharset

A CRYPT_XML_CHARSET value that specifies the character set of the encoded XML.

[in, out] pvCallbackState

A pointer to an argument that is passed to the callback function pointed to by the pfnWrite parameter.

[in] pfnWrite

A PFN_CRYPT_XML_WRITE_CALLBACK callback function that receives the encoded XML.

If the function succeeds, the function returns zero.

If the function fails, it returns an HRESULT value that indicates the error.
