Have been puzzled by the question of the quality code and protect itself from hacking and illegal use. Software solutions were considered, however, is now interested in is hardware. Has anybody used, or can be used, something like a HASP key (I only know the Sentinel Protection from safenet-inc, know any other?) or dongle (HASP there, too, but still, plus a bunch of other technologies).
I ordered a kit from Guardant'a — going to experience.
About hacking... Yes, there are emulators, but their writing is not a trivial task. For the same Guardant'and found nothing for the new versions (although it can be bad looking).
What do you use? Interested in is hardware. Worked somebody light with Guardant?
