Red Hat Enterprise Linux 8 GnuTLS Cryptographic Module
Red Hat Enterprise Linux 8 GnuTLS Cryptographic Module, from Red Hat®, Inc., holds FIPS 140-2 certificate #4428 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.
Caveat: When operated in FIPS mode and installed, initialized and configured as specified in Section 9 and 10 of the Security Policy. 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.
