Patches Patched in https://github.com/kudelskisecurity/crystals-go/pull/21 Note This library was written as part of a MsC student project in the Cybersecurity Team at Kudelski Security. It is not actively maintained anymore. It is only intended for research and testing. We discourage its use in any production environment. Kudelski Security does not use this library as part of their commercial offers or product. This has now been clarified on the project's README.
