Cisco Systems Libreswan Cryptographic Module

FIPS 140-2 certificate #3534 · Cisco Systems, Inc. · data as of 2026-10-21

Cisco Systems Libreswan Cryptographic Module, from Cisco Systems, Inc., holds FIPS 140-2 certificate #3534 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 dependency on certificate #2984. Federal agencies may reference historical validations for existing systems only, not for new procurement.
Caveat: When operated in FIPS mode with module Cisco Systems NSS Module validated to FIPS 140-2 under Cert. #3554 operating in FIPS mode and Cisco FIPS Object Module validated to FIPS 140-2 under Cert. #2984 in FIPS mode.
