Red Hat Enterprise Linux 8 GnuTLS Cryptographic Module

FIPS 140-2 certificate #3956 · Red Hat®, Inc. · data as of 2026-10-09

Red Hat Enterprise Linux 8 GnuTLS Cryptographic Module, from Red Hat®, Inc., holds FIPS 140-2 certificate #3956 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. SP 800-56Arev3 transition - replaced by certificate #4272. Federal agencies may reference historical validations for existing systems only, not for new procurement.
Caveat: When operated in FIPS mode. The module generates cryptographic keys whose strengths are modified by available entropy.

Module description

Quoted from the NIST CMVP entry for this certificate.

GnuTLS is a secure communications library implementing the TLS and DTLS protocols. It provides a simple C language application programming interface to access the secure communications protocols as well as APIs to parse and write X.509, PKCS#12, and other required structures which is shipped with Red Hat Enterprise Linux 8.
