lisp, des and bricscad

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.

        // Zoom to specified area

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.
