Protect! EXE/COM v.3.1

Bug Fixes/Updates
Protect! EXE/COM v.3.1
8/26/93
This was written mainly as a bug fix and a smaller step up, but here
is some of what I fixed:
* Took out the font enhanced screens of v.3.0. They caused way too many
problems and for some people, caused their systems to crash or screwed
up their screen modes (*sorry*!).
* Added support for Diet executable file compression.
* You no longer have to type the extension of the file to be protected.
* Made Protect! more compatible with some PKLite files.
* Slightly optimized for better performance in the security envelopes
at the cost of slower initial protection. (The files in this package
are also smaller).
If things have been going well for you with v.3.0, you really needn't
worry too much about this upgrade.
Protect! EXE/COM v.3.0
7/22/93
Here are some of the new features for version 3.0:
* The security envelopes have been entirely redone and rewritten
and have had new anti-debugging techniques added to them. (haven't
you heard this before?)
* UNP ver.3.11 cannot deprotect Protect! EXE/COM v.3.0.
* OVERLAYS are more tolerated and some types that could be compressed with
PKLITE can now be protected (sorry, but still not every overlay).
* REGISTERED users can CUSTOMIZE THE CRC ERROR MESSAGES and optionally
add a message to output when loading.
* No password is required (or asked for).
* The interface has been improved (especially for EGA monitors).
* A DOS ERRORCODE of 250 is returned on a CRC abort.
* You can now not have any parameters and SELECT THE FILE FROM A DIRECTORY
LISTING, having Protect! automatically compress the file with a file
compressor or just run things from the command line (BAT and MAK files
in particular).
Protect! EXE/COM 2.0
5/31/93
This copy has many security additions added to it. Loader code
and data is encrypted along with the regular encrypted program code.
Earlier versions have had a few vulnerable spots in them but are for
the most part safe. Both the COM and EXE loaders have been revamped and
there is more than one specific model for each loader. A few changes were
made so that the files will load a little faster also. Also, a few cosmetic
changes have been made to the actual program, but for the most part, the
changes were focused upon the loader's speed and security. This version
is much improved over previous versions partially due to letters and
comments from a few hackers and programmers. Weaknesses (particularily in
the COM files) were pointed out and greatly improved upon, so thanks
to everybody who wrote about Protect! EXE/COM!!! On the side note, you
may now have spaces in your password (you don't need underscores anymore)!
Protect! EXE/COM 1.1
4/26/93
This copy has been released to fix a bug that occurs on some
earlier XT computers when run. There is one instruction in the header
that is not recognized by the "genuine" 8088's and 8086's, but is only
recognized by the NEC V20, NEC V30, as well as the 286 and above. Since
the XT that I tested this on used the NEC V20 (8088 compatible chip with
a few enhancements) instead of the true 8088, it did not catch that error
as a true 8088 would have. Thanks to an alert user in Virginia, the error
was quickly caught and remedied (it took less than a half hour to fix),
and now Protect! EXE/COM v.1.1 will work on all XT-class computers.
Protect! EXE/COM 1.0
