Function Documentation

bool _CNGVerify	(	const CPKIFKeyMaterial &	key,
		unsigned char *	pHashData,
		int	nHashDataLen,
		unsigned char *	pSignature,
		int	nSignatureLen,
		PKIFCRYPTO::HASH_ALG	ha
	)

Interface: Module

This is a helper function called in Verify

Returns:

This function returns true if the signature verifies and false otherwise. Some errors can result in exceptions

Exceptions:

	CPKIFCryptoException(PKIFCAPI_CREATE_CERT_FAILED)
	CPKIFCryptoException(PKIFCAPI_ACQUIRE_CONTEXT_FAILED)
	CPKIFCryptoException(PKIFCAPI_KEY_IMPORT_FAILED)
	CPKIFCryptoException(PKIFCAPI_KEY_MATERIAL_NOT_SUPPORTED)

Parameters:

key	[in] Reference to a CPKIFKeyMaterial object containing key material to use when verifying the signature
pHashData	[in] Pointer to a buffer containing the message digest that was signed to produce the signature conveyed via the pSignature parameter
nHashDataLen	[in] Integer indicating the length of the value passed via the pHashData parameter
pSignature	[in] Pointer to a buffer containing the signature to verify
nSignatureLen	[in] Integer indicating the size of the value passed via the pSignature parameter
ha	[in] Hash algorithm used with signature
