  • If you've found a deficiency in .DES encryption, then it would be best to raise a support request with Bricsys.

    Raise a support request on LISP.

    You will be able to talk to them more plainly on the issue you've found and hopefully get it fixed.

  • I did a bit of searching and found this. https://www.codeconvert.ai/lisp-to-csharp-converter

    I would appreciate if some one could see if its useable, I dont program in C.

  • encrypting a Lisp file for Bricscad,

    and "converting" this file to C#

    are TWO SEPARATE TOPICS...

    and the second one

    (even though it's an interesting thing)

    is not

    the solution to the first one ...

    I don't understand why the response yes it has been disclosed that des is not maybe secure, but higher level languages like C# are more secure so it may be a way of securing the code you have invested your time and effort into.

    The convert to C is offered as an alternative to making des files. I don't use Visual Studio so don't know next step.

    This is what you hinted at Post 37 over at Theswamp.

    • the software to convert (CodeConvert) Lisp to C#,
      offers many other types of conversion from many languages ​​to many other languages
    • the procedure seems to be based on artificial intelligence
    • I suggest you download a large and fairly complex lisp file, translate it into C# with CodeConvert, compile it, load it into Acad, and thoroughly test the behavior of the software
    • if all goes well, we can say that codeConvert offers us a real alternative to encrypting Lisp files in Fas or Des format
    • anyway all this is interesting, but this does not mean that it is not better for ACAD and BCAD to encrypt Lisp files obtaining a non-vulnerable result

    and do the tests I told you and then let us know
