Support Cycle

This page provides you with information regrading support cycles for technologies provided by Cryptolens.

Client Libraries

.NET Client

Cryptolens.Licensing and Cryptolens.Licensing.CrossPlatform are the up-to-date client libraries (see what’s new). SKGLExtension is no longer maintained.

C++ Client

Customers need to install newest updates of Cryptolens Client API for C++ in order remain supported. New versions of the library are always backward compatible. Master branch contains the stable version of the library and “future” branch contains new features that will soon be released.

Python 2 & 3

Both versions of the Python client libraries are maintained. Python 3 is currently under active development. We recommend all customers to use the Python 3 version. Python 2 is still maintained and supported, but it might not have all the new methods. If you find a method that is missing, let us know and we will add it.


The Java library comes in two different builds, both are actively maintained. The latest release can be downloaded here.


The C library is production ready, but might not have all API endpoints implemented.

License Server

The license server has two versions, v1.0 and v2.*. If you want to get access to the latest features, we recommend to use v2.*, which will receive new updates. v1.0 is not actively maintained, however, existing premium customers using it production will still receive support for v1.0.


Web API has different versions in order to support different types of protocols, currently v2 and v3 are available. A Web API version is supported throughout its development and maintained a year after notice of discontinuation. If maintenance is deemed to be required longer, this period may be prolonged.
