License Manager

License Manager is a program that allows you to license your own software. It is designed so that working with the utility does not require any third-party software solutions other than the License Manager itself, the licensed product and the Microsoft .NET Framework 4 that it runs on.

Issued licenses are compatible with major online sales channels and payment providers such as PayPal, Amazon, Kagi, Stripe and FastSpring, which greatly facilitates further distribution of your project. Besides, the program works with .NET applications regardless of the language they are written in (C#, VB.Net, F#). There is also a function to choose one of two security levels: a low-grade level that works down to Windows XP and in regions where strong cryptography is not allowed, and a high-grade level with RSA or ECC encrypted serial keys. These levels discourage casual copying of your product, and the program supports trial, time-limited and user-specific license codes. It is sold as an annual subscription with a 30-day trial.

Lets small software vendors issue and validate secure serial keys for their .NET applications without building their own licensing system.
