  /* 
   *  The DUMMY algorithm driver does NOT encrypt data, it only copies data
   *  from SrcBuffer (source buffer) to DstBuffer (destination buffer).
   *
   *  You may insert your own encryption algorithm implementation to the 
   *  procedure, as well as your own Initial Vector calculation which 
   *  may be based on the IVector calculations made by other modules 
   *  of BestCrypt. Everything will work correctly, because the algorithm 
   *  driver is the only module in BestCrypt responsible for encryption.
