Thank you guys!!
Since I check up yesterday I've seen that it has been a very lively conversation.

Autodesk has the Entitlement API, which is supercool from a developerís perspective.
BricsCAD, well I think you need to pre upload keys, so I donít see how to use hardware info like a MAC address.
Thank you Daniel. I had no idea that the Entitlement API existed!!
For what I read it allows you to also manage a subscription, so I suppose you can publish and let test free for a month and then manage an annual subscription.
Also thanks for your code.
That corroborates my idea of accessing the method with the "WinHttp.WinHttpRequest.5.1" object in lisp.
About the decryptions, absolutely not idea.
Thank you all guys, again.

I apologize for my great ignorance,
but ...

how do you calculate this code ?

and then how is it used to decrypt ?

is there no relation to what vl-string-translate does?
it's base64

Just a bit of old fashioned help we had a application with multiple lisps, testing was done un locked so you can use old fashioned DOS bat file to add a users key etc to all files then say make a fas.

copy serial.lsp+lisp1.lsp d:\\Serial\\lisp1.lsp
copy serial.lsp+lisp2.lsp d:\\Serial\\lisp2.lsp
and so on

so the serial.lsp would be edited for each user changing their key. All required files now have the serial key in them.

copy serial.lsp+lisp1.lsp d:\\Serial\\lisp1.lsp
copy serial.lsp+lisp2.lsp d:\\Serial\\lisp2.lsp
and so on
copy /b serial.fas + lisp1.fas d:\\Serial\\lisp1.fas
This is also true

Thanks BIGAL, baitang36.
That's is a nice strategy to protect lisp files.
In my case I will be using a VLX obviously exposed to bad-cracking as suggested by d2010.
