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 developer’s perspective.
BricsCAD, well I think you need to pre upload keys, so I don’t 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.
