Function Documentation

GShandle InitializePKC (  GSCRYPTO_PKC_ALGO  eAlgo  ) 
 

Description:
This function will initialize the hash context. This must be called before any call to the UpdateHash() function. This function will return GS_FALSE if the hash context is not yet terminated.
Returns:
Status of the function call
Return values:
Identification of the hash algorithm created
NULL if the operation failed
Parameters:
IN eAlgo The type of hash algorithm to use.

GSvoid UninitializePKC (  GShandle  hPKC  ) 
 

Description:
Uninitiaze the hash module
Returns:
void
Parameters:
hHash Handle on the hash module
