Module description

Quoted from the NIST CMVP entry for this certificate.

The Microsoft Windows Cryptographic Primitives Library is a general purpose, software-based, cryptographic module. The primitive provider functionality is offered through one cryptographic module, BCRYPT.DLL (versions 7.00.2872 and 8.00.6246), subject to FIPS 140-2 validation. BCRYPT.DLL provides cryptographic services, through its documented interfaces, to Windows Embedded Compact 7 and 2013 components and applications running on Windows Embedded Compact 7 and 2013.
