Key Generation and Verification System component for Microsoft .NET applications (.NET 2.0 and above)
A common requirement for software vendors is the inclusion of a system for generating and verifying passwords, which can be bundled with distributed desktop software, or for granting access to online services. App Software's .NET Licence Engine SDK provides a robust, lightweight and tested means of solving this problem.
The .NET Licence Engine SDK implements a 'Partial Number Verification System', which along with other features, provides a defence against key generators which may be built to attempt to crack your licence key system.
