C# .NET FIPS Roadmap

Current FIPS Overview

The BC FIPS C# .NET User Guide contains details about the API and use of the BC FIPS C# .NET module.

The API is different from the regular C# API as it makes use of generics and needs to meet the FIPS boundary requirements. This has lead to an API that is similar in feel to the FIPS Java low-level API, but somewhat smaller as the use of C# generics has reduced the code size.
