M ABSTRACT: This program is a general purpose fast encryption routine that will A 	  perform "in-place" encryption on any type of file. Unlike most C 	  encryption programs there is no restriction on file type, record D 	  length, file size, or text verses data. This program will encryptG 	  anything as long as there is enough virtual memory to load the file. G 	  A benifit of encrypting the file in memory is that the encryption is  	  quite fast.  I 	  The program is designed to be envoked by DCL, and effectively replaces C 	  the ENCRYPT command supplied by Digital. However, the encryption F 	  algorithm could be easily extracted from the program and used as to: 	  perform in line encryption from a user written program.  @ 	  The program has the same functionality as Digital's command, G 	  including the ability to encrypt a list of files in the one command. 
