Mobile Application Cryptographic Module

FIPS 140-2 certificate #2465 · Silent Circle · data as of 2026-10-09

Mobile Application Cryptographic Module, from Silent Circle, holds FIPS 140-2 certificate #2465 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. 186-2 transition. Federal agencies may reference historical validations for existing systems only, not for new procurement.
Caveat: When operated in FIPS mode. This validation entry is a non-security relevant modification to Cert. #1938. The module generates cryptographic keys whose strengths are modified by available entropy.
