Module Name:

    FrontCrypt

Abstract:

    This header file provides a front end to the CryptoAPI V1.0 calls,
    simplifying the calling interface by using CBuffer objects for the return
    values, and directly returning error codes.  It also supplies missing calls
    on earlier operating systems.
