Cryptolens.Licensing (aka SKM Client API) is a free of charge, open source library that provides additional methods for the functionality available in the Cryptolens platform. One of the examples is key activation. In other words, it is used to simplify interaction with the Web API.
Note: The use of most of the methods requires an active subscription.
Note: If you plan to use the client with Mono (eg. in Unity) or on Linux/Mac, you need to use the cross platform version of the library, Cryptolens.Licensing.CrossPlatform, which is available on NuGet. You can also download the pre-compiled binaries here.
