Description
The Sentinelle company has developed a revolutionary license control system with wave-based presence verification. You are invited to test this new product, Steel Sentry, in order to verify its robustness before purchasing it.
Normally, this product is supplied with a hardware component connected to the PC to ensure foolproof protection. In your case, and because Sentinelle does not want an overly intrusive security evaluation, you will only be given a test software version. To make things even more difficult, the company has configured its license server so that, even if you were to get hold of such a dongle, you still would not be able to pass the verification.
Will you still manage to find the license?
