Module 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.
Approved algorithms
