Module Name
Microsoft Windows 7 Kernel Mode Cryptographic Primitives Library (cng.sys)
Historical Reason
RNG SP800-131A Revision 1 Transition
Caveat
When operated in FIPS mode with Windows 7 Winload OS Loader (winload.exe) validated to FIPS 140-2 under Cert. #1326 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 7 kernel components. It supports several cryptographic algorithms accessible via a FIPS function table request irp (I/O request packet).
Tested Configuration(s)
- Microsoft Windows 7 Ultimate Edition (x64 version)
- Microsoft Windows 7 Ultimate Edition (x86 Version)
- Microsoft Windows 7 Ultimate Edition SP1 (x64 version) (single-user mode)
- Microsoft Windows 7 Ultimate Edition SP1 (x86 version)
