mhhhh.... I don't trust it too much, and it's usually defeated using some emulator like vmware and also in wine....

Btw, the problem of changing an hard disk / network card is there, and you can't do anything about it.
If customer is "smart" he can tell you he changed something and ask for a new auth code, and you can't say simply no....

Hello Massimo

It is true. Anyway if when asking for the key the user sends you all that info (encrypted):
- you know if it is run on a virtual system. You can deny it
- If they say they changed the HD, you will see everything unchanged but the HD code Smile
- Nowadays all PCs have an embedded network hardware so you have a MAC. It is of course possible to change the MAC, but computers with the same MAC cannot live in the same network Smile.

They can purchase PC clones with the same MAC unconnected to LAN or Internet... well but different HD so ... Smile. It is very difficult to handle.

Because of it I think it is worthwhile to have the key in a file. Many people does it alone or combining it with a web authentication just when Internet is available.


Best regards
IƱaki
