Module description

The Enhanced DSS and Diffie-Hellman Cryptographic Provider (DSSENH.DLL) encapsulates several different cryptographic algorithms in an easy-to-use cryptographic module accessible via the Microsoft CryptoAPI. It can be dynamically linked into applications by software developers to permit the use of general-purpose FIPS 140-2 validated cryptography. This cryptographic module also maintains FIPS 140-2 validation compliance (according to FIPS 140-2 PUB Implementation Guidance G.5) on Microsoft Windows 8, Microsoft Windows 8 Pro, and Microsoft Windows Server 2012 Datacenter.
