Cryptographic Primitives Library (bcryptprimitives.dll and ncryptsslp.dll) in Microsoft Windows 10, Windows 10 Pro, Windows 10 Enterprise, Windows 10 Enterprise LTSB, Windows 10 Mobile, Windows 10 for Surface Hub

Microsoft Corporation - FIPS 140 #2606

historicalLevel 1

The Cryptographic Primitives Library (bcryptprimitives.dll and ncryptsslp.dll) provides cryptographic services to Windows components and applications. It includes cryptographic algorithms in an easy-to-use cryptographic module via the Cryptography Next Generation (CNG) API. It can be dynamically linked into applications for the use of general-purpose FIPS 140-2 validated cryptography.
