SX-590-1402

FIPS 140-2 certificate #4241 · silex technology, Inc. · data as of 2026-10-09

SX-590-1402, from silex technology, Inc., holds FIPS 140-2 certificate #4241 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.

Historical. Moved to historical list due to sunsetting. Federal agencies may reference historical validations for existing systems only, not for new procurement. Observed moving to historical on 2026-09-22. It was one of the last FIPS 140-2 certificates, all moved at the 140-2 sunset on 2026-09-21.
Caveat: When operated in FIPS mode. The module generates cryptographic keys whose strengths are modified by available entropy
