Module Name
Microsoft Windows Server 2008 R2 Kernel Mode Cryptographic Primitives Library (cng.sys)
Historical Reason
RNG SP800-131A Revision 1 Transition
Caveat
When operated in FIPS mode with Windows Server 2008 R2 Winload OS Loader (winload.exe) validated to FIPS 140-2 under Cert. #1333 operating in FIPS mode
Embodiment
Multi-chip standalone
Description
CNG.SYS runs as a kernel mode export driver, and provides cryptographic services, through their documented interfaces, to Windows Server 2008 R2 kernel components. It supports several cryptographic algorithms accessible via a FIPS function table request irp (I/O request packet).
Tested Configuration(s)
- Microsoft Windows Server 2008 R2 (IA64 version)
- Microsoft Windows Server 2008 R2 (x64 Version)
- Microsoft Windows Server 2008 R2 SP1 (IA64 version) (single-user mode)
- Microsoft Windows Server 2008 R2 SP1 (x64 version)
