BC-FNA (Bouncy Castle FIPS .NET API)

FIPS 140-2 certificate #4416 · Legion of the Bouncy Castle Inc. · data as of 2026-10-09

BC-FNA (Bouncy Castle FIPS .NET API), from Legion of the Bouncy Castle Inc., holds FIPS 140-2 certificate #4416 at overall level 1. The validation is historical: agencies may keep the module in existing systems but not buy it new. Below are its algorithm certificates, its validation history, and the list moves this tracker has observed, which NIST does not date.

Historical. Moved to historical list due to sunsetting. Federal agencies may reference historical validations for existing systems only, not for new procurement. Observed moving to historical on 2026-09-22. It was one of the last FIPS 140-2 certificates, all moved at the 140-2 sunset on 2026-09-21.
Caveat: When operated in FIPS mode. No assurance of the minimum strength of generated keys.

Module description

Quoted from the NIST CMVP entry for this certificate.

The Bouncy Castle FIPS .NET API is a comprehensive suite of FIPS Approved algorithms implemented in pure C#. All key sizes and modes have been implemented to allow flexibility and efficiency, and additional algorithms, including some post-quantum ones, are available in non-approved operation as well.
