Secure vlx file
« on: December 20, 2020, 02:28:34 AM »
Hello everyone,
Recently, VLX programs are decompiled easily, and also .FAS files, it's not interesting, because we all have an Autolisp program that we want to keep it safe. so I'm going to find a way to bypass decompilers and keep VLX safe from the tools. what do you think? is there any way or trick to do that?

Thanks in advance.

You really have to work on the 99.9% theory that is that the majority have no idea how to crack a program and then change it.

I know of $9,000 software that was cracked and could be bought for like $100 out of a Asian country. This was cracked at assembler level edit the exe.

(:lol:  "You must compile AutoLisp-source.Lsp with "Compile to=> Mode/Jc_pin15.lsp")
Even, the most badHacker person, can not recover/crack your source.ascii.Lisp from isInside program.Vlx(or .Fas or .Des)

I agree with you, but the highest protection version of AutoLisp is VLX file, while I have seen a simple and free tool on the web so that any ordinary users can cracks any VLX file easily. actually I'm not trying to full protect or achieve 99.9 % protection of lisp file, currently I'm a trying to find a way to secure my file from typical users or the tool.

There is a point that is  the software with $9,000 cost may be broken by 1% of users. and also the such software are very common and known.

I couldn't find any information about "Compile to=> Mode/Jc_pin15.lsp", what is it? could you give more explanation?

I've installed last version of the program, Does it have a guidance to use?
The program is confusing,  has many option and menu, where can I compile lsp in the program?
I see this window after running it :

It is a mature technology to decompile Fas into LSP. I have decompiler tools in my hand.
 In order to protect the source code, I developed a protection tool, by modifying Fas to make it unable to be decompiled.
It comes in two versions, free and paid. Free version is relatively simple, suitable for free software, need friends contact me: 5520971@qq.com

Decompiler tools can only decompile standard Fas files. My counter measure is to make Fas no longer standard. I can change the instructions of Fas and use some rare instructions. You can also add a goto instruction to it, because there is goto in FAS, but not in LSP.

Now , you can to generate all possible geometry/trigonometry of MathematicalFormulas - in modelspace.

step0)You use, two-submenu (FileDia and Run-AltR") you total-ignore others submenu+option/s), because  other/s are unusefull for compile.
step1) You start your-mini-project.vlax

I couldn't use the program,
Could you compile this lsp file for test:

Could you compile this lsp file for example:
You need daily-chatting. you must, make user -account on the "lisp2arx forum.ro" with google.com. I don't; need spam "the swamp forum  lisp" with message/s
Code: [Select]
(defun c:snu3 (/ xorg ss)
  (vl-load-com)
  (setq ss (ssget (list (cons0  "TEXT,MTEXT"))))
  (setq tare
(alert
   (strcat
     "Sum of numbers: "
     (rtos
       (apply
(read "+")
(MAPCAR
   (function (LAMBDA (Xorg)
      (atof (vlax-get (vlax-ename->vla-object X) (read "Textstring"))
    )
   (vl-remove-if (read "listp") (mapcar (read "cadr") (ssnamex ss)))
)
       )
       2
       4
     )
   )
)
  )
You have only 23% from 100% rights.
If you decompile .Fas to .Lsp, then you see "Registration-codes/store inside vlx or .fas" and the Mr-civil.eng-person cannot sell any "civil-eng.vlx" on www.Autodesk-appStore.com.
Code - Auto/Visual Lisp: [Select]
  1. #region
  2. c_snu3
  3. (defun c_snu3 (/ xorg ss)
  4. /*c2s:   vl.load_com();
  5.          ss=ssget(lISt(cons(0,"TEXT,MTEXT"))),
  6.          tare=alert(strcat("Sum of numbers: ",rtos(apply(read("+"),
  7.                 mapcar(function(lambda(xorg(),
  8.              atof(vlax.get(vlax.ename->vla_object(Xorg),read("Textstring"))),
  9.                     vl.remove_if(read("listp"),mapcar(read("cadr"),ssnamex(ss))))),2,4)))));
  10.  // e-setq2#0
