RE: [PHP] Genus who came up with "Self Destruct Code" & "Copy Pro tection"

That's what I mean. Adding some code that controls the use of the product. Maybe not that it works for a certain amount of time. Instead one can use license keys that allow to check if the script is used under the correct domain (it has been buyed for). It certainly depends on the situation and is useless if you develop a php script under a contract. I share the opinion that in that case it is not a technical, but a legal problem. It changes however if you devlop a product yourself, sell it to your customers and don't want them to create illegal copies. The prerequisite of such a protection is, that it can't be broken easily (that is, when the code is public). tongo@bossig.com (Carl Brandenburg) wrote in news:NDBBIEGBMDJFPGJOBIEFMECKHNAA.tongo@bossig.com: > For my two bits, couldn't a developer script in an activation key that > would be required after a trial period (say 30 or 60 days or > something)?
