Microsoft Corporation - FIPS 140 #1891

historicalLevel 1

Kernel Mode Cryptographic Primitives Library (CNG.SYS) runs as a kernel mode export driver, and provides cryptographic services, through their documented interfaces, to Windows kernel components. It supports several cryptographic algorithms accessible via a FIPS function table request IRP (I/O request packet). 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.

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 Boot Manager validated to FIPS 140-2 under Cert. #1895 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 BitLocker® Windows OS Loader (WINLOAD) validated to FIPS 140-2 under Cert. #1896 operating in FIPS mode. The module generates cryptographic keys whose strengths are modified by available entropy.
