Microsoft Enhanced Cryptographic Provider
Microsoft Corporation - FIPS 140 #238
The Microsoft Enhanced Cryptographic Provider (RSAENH) is a FIPS 140-1 Level 1 compliant, general-purpose, software-based, cryptographic module. Like other cryptographic providers that ship with Microsoft Windows XP, RSAENH encapsulates several different cryptographic algorithms (including SHA-1, DES, 3DES, AES, RSA, SHA-1-based HMAC) 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 140-1 Level 1 compliant cryptography.
