Windows Server 2008 R2 Enhanced Cryptographic Provider (RSAENH)

FIPS 140-2 certificate #1337 · Microsoft Corporation · data as of 2026-10-21

Windows Server 2008 R2 Enhanced Cryptographic Provider (RSAENH), from Microsoft Corporation, holds FIPS 140-2 certificate #1337 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 sunsetting. Federal agencies may reference historical validations for existing systems only, not for new procurement.
Caveat: When operated in FIPS mode with Windows Server 2008 R2 Code Integrity (ci.dll) validated to FIPS 140-2 under Cert. #1334 operating in FIPS mode and Microsoft Windows Server 2008 R2 Kernel Mode Cryptographic Primitives Library (cng.sys) validated to FIPS 140-2 under Cert. #1335 operating in FIPS mode.
