Program: ICE.COM Intrusion Contermeasure Electronics COM file Security Program Version 1.00 Copyright 1988 by Keith P. Graham Contact: Keith P. Graham c/o PC-Rockland BBS (914) 353-2157 Description: ICE is a program which scramples and compresses COM files (not EXE files) yet allows them to be fully functional. The program makes it difficult to alter the orginal program and it has the added bonus of compressing COM files without detracting from their usefulness. ICEd COM files still run as they did before except that they are usually smaller and disk load times are shorter. ICE offers protection agains viruses in that ICE can scramble COMMAND.COM and make it difficult for viruses to attach themselves to the scramble program. Usage: The format of the ICE command is: ICE file.COM encryption-key file is the name of a COM file to ICE and encryption key is a string of numbers and/or letters that will help make your scramble unique. ICE will compress and scramble the com file and replace the original. It is important to have a backup of the original COM file in case ICE screws up somehow. I have tested ICE, but it is possible to screw anything up. Disclaimer: I have written an ICE BREAKER for ICEd programs and I am sure that any good hacker could also figure it out after a while. No software resource can be protected entirely by software. I can only guarantee that ICE makes COM file safer, not 100% safe. License: ICE remains the property of Keith P.
