Thank. I think I need to ask how to verify these keys?
- arcticwombat 8y agoThere are different ways to do it depending on if the client is online or if it has to be offline, and using a dongle or not (Uncommon today). If the client will be online you can just do an API call and check on start, if there's no key show a splash screen with the option of entering a key. If there IS a key, send it (securely) to the API and do something depending on the result. Here's a good article for how you could do it for offline keys: https://www.brandonstaggs.com/2007/07/26/implementing-a-partial-serial-number-verification-system-in-delphi/ https://www.brandonstaggs.com/2007/07/26/implementing-a-part... It's written for Delphi/Object Pascal but the principles can be implemented in any language.
- Jumboo 8y agoThanks for the link. I think this is what I need.
- Academ1c 8y agoYou should write your own algorithm for creating the KeyGen. Also, think about how the key will be checked. The key can be tied to the MAC address of the computer. But this way has some pros and cons.
- Jumboo 8y agoThanks for the tip. I found several ways to generate keys. But I don’t know how to organize the process of checking and locking the keys when they are transferred to third parties.
- Academ1c 8y agoMaybe you should try a ready-made licensing system? Try ready-made DRM-systems (Digital rights management). You can find a lot of information on Wikipedia. There are examples of free and paid programs. Also, you can use a ready-to-use key-making tool. ArmDot for example. As usual, such programs are paid. But maybe you can find something free on the GitHub. Good luck!
- Jumboo 8y agoThanks for the tip. I will study this question in more detail.
