100% .NET solution for licensing controls and applications written with any language designed for the .NET Framework (C#, VB.NET etc). Currently available for .NET Framework 1.1 & 2.0. It uses 2 different licensing schemas: Licensing by issue license file, and Licensing by secure encrypted license keys. Main features: 1.Strong license file and unlock key encryption. 2.Flexible license file content. It allows you to create different license types that fit your needs using 17 different validators and unlimited number of the custom fields. 3.Custom license fields. It allows you to store any additional information in the license file, so you can lock/unlock some features of your product, or make some additional tests to validate license. 4.Component/Control Licensing. 5.Time/Usage Limited Evaluation. Manco.Licensing System allows you create evaluation version of your product that is limited by running time (you can set expiration date or number of days before license expiration), number of runs or some features of the product. 6.Signed license file. Manco.Licensing system uses strong RSA encryption to sign license files. 7.Activate by Unlock Key. Use strong RSA encrypted unlock keys to activate your application or control. 8.Create encrypted code and data. Manco.Licensing System allows you to encrypt key application data or source code with separate parameters and keys (not the same ones that are used to encrypt/decrypt license) using functionality provided by Manco.LicenseGenerator. Then encryption parameters and keys are included into the license file as custom values. You can include encrypted data and source code into your project and then decrypt, compile and load them into memory in runtime using functionality provided by Manco.Licensing.License class. After that this compiled code can be used in the application or control. 9.Source Code Integration. 10.License Generator. This is the full functional application for complete license and customer management.
