  • Article

The CryptXmlDllVerifySignature function verifies a signature.

The CryptXmlDllVerifySignature function is exposed through the exported CryptXmlDllGetInterface function.

Syntax

CryptXmlDllVerifySignature Cryptxmldllverifysignature;

HRESULT Cryptxmldllverifysignature(
  [in] const CRYPT_XML_ALGORITHM *pSignatureMethod,
  [in] BCRYPT_KEY_HANDLE hKey,
  [in] const BYTE *pbInput,
  [in] ULONG cbInput,
  [in] const BYTE *pbSignature,
  [in] ULONG cbSignature
)
{...}

Parameters

[in] pSignatureMethod

A pointer to a CRYPT_XML_ALGORITHM structure that specifies the algorithm.

[in] hKey

A handle to the public key.

[in] pbInput

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

[in] cbInput

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

[in] pbSignature

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

[in] cbSignature

The size, in bytes, of the pbSignature buffer.
