BC-FNA (Bouncy Castle FIPS .NET API)

FIPS 140-2 certificate #2792 · Legion of the Bouncy Castle Inc. · data as of 2026-10-21

BC-FNA (Bouncy Castle FIPS .NET API), from Legion of the Bouncy Castle Inc., holds FIPS 140-2 certificate #2792 at overall level 1. The validation is historical: agencies may keep the module in existing systems but not buy it new. Below are its validation history, algorithm certificates and security policy, drawn from the NIST CMVP entry.

Historical. Moved to historical list due to sunsetting. Federal agencies may reference historical validations for existing systems only, not for new procurement.
Caveat: When installed, initialized and configured as specified in the Security Policy Section 8 and operated in FIPS mode. The module generates cryptographic keys whose strengths are modified by available entropy. 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.
