FIPS 140-2 certificate #1894 · Microsoft Corporation · data as of 2026-09-03

Microsoft Windows 8, Microsoft Windows Server 2012, Microsoft Windows RT, Microsoft Surface Windows RT, Microsoft Surface Windows 8 Pro, Microsoft Windows Phone 8, and Microsoft Windows Storage Server 2012 Enhanced Cryptographic Provider (RSAENH.DLL), from Microsoft Corporation, holds FIPS 140-2 certificate #1894 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 #1892. Federal agencies may reference historical validations for existing systems only, not for new procurement.
Caveat: When operated in FIPS mode with modules Microsoft Windows 8, Microsoft Windows Server 2012, Microsoft Windows RT, Microsoft Surface Windows RT, Microsoft Surface Windows 8 Pro, and Microsoft Windows Phone 8 Code Integrity (CI.DLL) validated to FIPS 140-2 under Cert. #1897 operating in FIPS mode, Microsoft Windows 8, Microsoft Windows Server 2012, Microsoft Windows RT, Microsoft Surface Windows RT, Microsoft Surface Windows 8 Pro, and Microsoft Windows Phone 8 Cryptographic Primitives Library (BCRYPTPRIMITIVES.DLL) validated to FIPS 140-2 under Cert. #1892 operating in FIPS mode, and Microsoft Windows 8, Microsoft Windows Server 2012, Microsoft Windows RT, Microsoft Surface Windows RT, Microsoft Surface Windows 8 Pro, and Microsoft Windows Phone 8 Kernel Mode Cryptographic Primitives Library (CNG.SYS) validated to FIPS 140-2 under Cert. #1891 operating in FIPS mode.

Module description

Quoted from the NIST CMVP entry for this certificate.

The Enhanced Cryptographic Provider (RSAENH.DLL) encapsulates several different cryptographic algorithms in an easy-to-use cryptographic module accessible via the Microsoft CryptoAPI. It can be dynamically linked into applications by software developers to permit the use of general-purpose FIPS 140-2 validated cryptography. This cryptographic module also maintains FIPS 140-2 validation compliance (according to FIPS 140-2 PUB Implementation Guidance G.5) on Microsoft Windows 8, Microsoft Windows 8 Pro, and Microsoft Windows Server 2012 Datacenter.
