DataKrypto Fully Homomorphic Encryption Module

FIPS 140-2 certificate #4677 · DataKrypto US, Inc. · data as of 2026-10-09

DataKrypto Fully Homomorphic Encryption Module, from DataKrypto US, Inc., holds FIPS 140-2 certificate #4677 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. No assurance of the minimum strength of generated keys

Module description

Quoted from the NIST CMVP entry for this certificate.

The DataKrypto Fully Homomorphic Encryption Module is a cryptographic engine for DataKrypto's Fhenom and Fhenom for Images. Fhenom is a fully homomorphic encryption module. Fhenom for Images is a fully homomorphic image encryption module that allows images to be processed while remaining images. Both products use core cryptographic functions to perform secure key management, data integrity and secure communications.
