Function Documentation

bool _Verify ( const CPKIFKeyMaterial &  key,
unsigned char *  pHashData,
int  nHashDataLen,
unsigned char *  pSignature,
int  nSignatureLen 
)

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
