Protect! EXE/COM v6.0
(C) 1993-1996 Jeremy Lilley
All Rights Reserved
Thank you for obtaining Protect! EXE/COM v6.0 to evaluate!
What is Protect!?
-----------------
If you're unfamiliar with Protect!, it is an encryption and
anti-hacking program for EXE and COM files. Protect! will encrypt
your regular DOS EXE and COM program files to make them difficult
to modify or to reverse-engineer.
Some features include:
* Modification detection
* Optional password prompting
* Encrypted serialization and file source tracking
* Anti-debugging traps and a custom mutation engine
* Differentiation in the registered version
* Customizability option with the ProtExCm.INI file
* Executable compression
These are all described in more detail in the ProtExCm.DOC,
but the all are aimed to increase the security of your programs --
whether to prevent "missing" copyright screens, reverse-engineering
and hard-core hacking or just to make the strings in your
end-executables unreadable.
Quick Syntax
------------
To Protect a file, simply run ProtExCm.EXE:
PROTEXCM MYPROG[.EXE or .COM] [MYPROG.INI]
The INI file, a new feature in this version, will be
ProtExCm.INI or "FileName".INI by default, and it allows
many options, including passwords, serialization, and,
for registered users, customizing the message displayed
when the file is modified.

Requirements for Protect!
-------------------------
There are no special requirements except that the file must
be DOS-based, non-overlaid, and under about 600k. Sometimes,
especially in large files, the number of relocation pointers
will require the program to be compressed with another compression
program such as PKLite or LZEXE in order to run efficiently when
Protected.
Registering Protect!
--------------------
For $25 plus shipping and handling, you can register
your copy of Protect! and legally use it on files you distribute.
The registered copy includes:
* One disk with Protect
* License to Protect an unlimited number of files
* Improved security code in the registered version
* Capability to customize the modification message
* Ability to change the prompt for optional passwords
* No registration reminder screen
* Update notices and support support
You can register by mail, through Compuserve, or by using
a credit card (see the instructions in ORDER.FRM for credit card
orders, which have to go through an ordering service).
In any case, thank you for evaluating Protect!
