What is bcryptprimitives.dll?
The genuine bcryptprimitives.dll file is a software component of Microsoft Windows Operating System by Microsoft Corporation.
"Bcryptprimitives.dll" is a Microsoft dynamic link library of routines implementing cryptographic primitives, fundamental building-block algorithms used in cryptographic systems. These algorithms are not complete cryptographic systems. They reliably perform one precisely-defined function such as a hash, random number generator (RNG), or symmetric or asymmetric encryption. The United States Federal Information Processing Standard 140, (FIPS-140), classifies primitives for encryption of sensitive but unclassified documents by 4 increasing levels of security; most Microsoft products meet level 1. For Windows 7 and Windows Server 2008 R2 and later, "bcryptprimitives.dll" is the library of FIPS-140-validated cryptographic primitives.
