Kdf108

Kdf108 is a .NET implementation of NIST SP 800-108 key derivation functions. It supports counter, feedback, and double-pipeline modes with HMAC and CMAC pseudorandom functions.

Requirements

• .NET 10 SDK for repository development
• .NET 8 or a .NET Standard 2.0-compatible runtime for library consumers

Build and test

dotnet restore
dotnet build --configuration Release
dotnet test --configuration Release

Packages

Kdf108 2.x targets netstandard2.0, net8.0, and net10.0. NuGet publishing follows signed version tags after the complete build and test workflow passes.

Conformance

The test suite includes NIST CAVP SP 800-108 response vectors. Passing these vectors demonstrates compatibility with those published test cases; it is not a NIST validation or endorsement.
