php - workflow for a license server / selling software -


I have a product that I sell, buy a user license key and enter the config to enable that product. We do.

My first idea was ..

Licensed server w / license key pings on product launch, and fails if the server returns an authorized (license terminated, invalid etc.). But what if the license server is down?

Another idea was that the license should be entered only once, or maybe every 30 days, or just every time (the app was reinstated.).

Is there any safe way to go about this (good protection from at least some script ceds)? I have never sold the software, but I know how easy it is to reverse-engineer / modify software to avoid the need for a license and to complicate things, it is in PHP.

The answer to the new product is always:

About copy protection Do not worry, unless people are actively tampering your product already, there is no reason to add the 'phone-home' feature.

Large companies may be crazy about proper licenses, so they will pay you for the license. Most small companies are ethical and issues of any license are probably an inspection. Now you should have more worry about removing your name and introducing people to your product. Anyone using your product at home who has never paid for a license, it is a good thing for you now to get people using your code, do so that turning businesses into something else is a tough time Then, worry about ensuring that they are not using it for free, this is a version 3 problem, if you remove it.
