Microsoft Corporation - FIPS 140 #2937
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.
