Module Name
Microsoft Windows Cryptographic Primitives Library (bcrypt.dll)
Historical Reason
RNG SP800-131A Revision 1 Transition
Caveat
When operated in FIPS mode with Code Integrity (ci.dll) validated to FIPS 140-2 under Cert. #890 operating in FIPS mode
Embodiment
Multi-chip standalone
Description
BCRYPT.DLL provides cryptographic services, through its documented interfaces, to Windows Vista components and applications running on Windows Vista.
The cryptographic module, BCRYPT.DLL, encapsulates several different cryptographic algorithms in an easy-to-use cryptographic module accessible via the Microsoft CNG (Cryptography, Next Generation) API. It can be dynamically linked into applications by software developers to permit the use of general-purpose FIPS 140-2 compliant cryptography.
Tested Configuration(s)
- Microsoft Windows Vista Ultimate Edition (x64 version) (single-user mode)
