The CryptXmlDllVerifySignature function is exposed through the exported CryptXmlDllGetInterface function.

Syntax


typedef HRESULT ( WINAPI *CryptXmlDllVerifySignature)(
  _In_ const CRYPT_XML_ALGORITHM *pSignatureMethod,
  _In_       HCRYPTXML_PROV      hCryptProv,
  _In_       HCRYPTXML_KEY       hKey,
  _In_ const BYTE                *pbInput,
  _In_       ULONG               cbInput,
  _In_ const BYTE                *pbSignature,
  _In_       ULONG               cbSignature
);

Parameters

pSignatureMethod [in]

A pointer to a CRYPT_XML_ALGORITHM structure that specifies the algorithm.

hCryptProv [in]

A handle to the cryptographic provider.

hKey [in]

A handle to the public key.

pbInput [in]

A pointer to a buffer that contains the signed data. The cbInput parameter contains the size of this buffer.

cbInput [in]

The size, in bytes, of the buffer pointed to by the pbInput parameter.

pbSignature [in]

A pointer to a buffer that contains the signature value to be verified. The cbSignature parameter contains the size of this buffer.

cbSignature [in]

The size, in bytes, of the pbSignature buffer.

Return value

If the function succeeds, the function returns zero.

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