Module description
Quoted from the NIST CMVP entry for this certificate.
The Microsoft Enhanced Cryptographic Provider, designed for FIPS 140-2 compliance, is a software-based, cryptographic module. RSAENH encapsulates several different cryptographic algorithms (including SHS, DES, TDES, AES, RSA, HMAC) in a cryptographic module accessible via the Microsoft CryptoAPI.
Approved algorithms (7)
Other algorithms
DES; MD2; MD4; MD5; HMAC MD5; RC2; RC4; RSA (key wrapping; key establishment methodology provides between 112 and 150 bits of encryption strength; non-compliant less than 112 bits)
Tested configurations
- Microsoft Windows XP Professional SP3 (single-user mode)
