Rancher Kubernetes Cryptographic Library

FIPS 140-2 certificate #3836 · Rancher Labs · data as of 2026-09-03

Rancher Kubernetes Cryptographic Library, from Rancher Labs, holds FIPS 140-2 certificate #3836 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. Federal agencies may reference historical validations for existing systems only, not for new procurement.
Caveat: When installed, initialized and configured as specified in Section 9.1 of the Security Policy and operated in FIPS mode. The module generates cryptographic keys whose strengths are modified by available entropy.
