Module description

Quoted from the NIST CMVP entry for this certificate.

BCRYPT.DLL provides cryptographic services, through its documented interfaces, to Windows components and applications running on Windows. The cryptographic module, bcryptprimitives.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.
