Title: Fas and VLX program protectors ver 1.05e
Post by: baitang36 on February 24, 2020, 02:00:09 AM
This program is a gift to LSP programming fans, after this program encryption VLX

and FAS files can not be decomcompiled.
It's very easy to use, click start, select a VLX or a fas file you want to encrypt,

click open, click ok, and the encryption is successful.
Encrypted files and source files in the same directory. Add _p to the filename。
If you have any Suggestions, please contact the author of this program sheng

Hello baitang36,
Please refrain from attaching binary/compiled files to a post. If you wish to share a binary/compiled file please ask for a private message or an email from people who are interested.

i've downloaded and tried baitang36's tool
not on my PC of course :)
it changes certain byte sequences in the vlx file
which i suspect baffles the decompiler

If you have decompiler software, try it out.I tried fastolsp.exe and it worked. A lot of net friend have tried, confirm effective.

If others are like you, the tool is useless.

fastolsp.exe does a good job?
how does the decompiled fas looks like?

I can't decompile neither VLX, nor VLX-P version, but now that you provided "protection" - P, I believe OP can decompile any version he gets in his hands...

But I don't care like VovKa, to me VLX as it is is fairly good compilation...

I think I only compiled one program for use and it was essentially just for packaging/ease of use reasons more then protection.

Decompiled can be run directly.
You can provide an fas file and I'll decompile it for you

You can send me a VLX file and I will try it for you

Since you package, just don't want people to see the source code. Decompiling tools are very popular today. Without protection, it's like running naked.

OK, you convinced us that you can do it... Now the challenge for you :
You need to check any of posted *.vlx files from here :
http://www.theswamp.org/index.php?topic=53008.msg579668#msg579668

The goal is that you hack it and tell us what the password is... VLX files are programmed to solve attempt of scaling non uniformly sel. set of 3DSOLID entites via AutoLISP... Although this was just good attempt, this solution can be accomplished well by using other software like Rhino and ACAD and by scripting for Rhino-CAD... Just a warning : VLX files are very well masked, and without plenty of skills it's very hard to achieve requested goal... I can give you a hint : password is only numerical...

If you can do it, I take my heat down to you...
Regards, M.R.

the code is not 100% correct
my (test) shows only one alert box, yours shows three
but it is VERY VERY close
really great tool

i will post my source tomorrow when i get to the office

Who is the author of this program? This encryption is very clever indeed, but any encryption exists to be cracked.

The author of this program is indeed a genius. IQ should be above 140, right?
It took me four hours to crack the code. STR=120497*
Can this encryption algorithm be exposed?
Maybe you don't want people to know,

I believe the word is: "HAT". "I take my hat off to you" is a compliment to you. The meaning of the phrase is: to praise, salute, or congratulate.
