Module description
Quoted from the NIST CMVP entry for this certificate.
The Windows Server 2003 Enhanced DSS and Diffie-Hellman Cryptographic Provider (DSSENH) is a FIPS 140-2 compliant, software-based, cryptographic module. DSSENH encapsulates several different cryptographic algorithms (including SHA-1, 3DES, DSA and Diffie-Hellman) in a cryptographic module accessible via the Microsoft CryptoAPI (CAPI).
Approved algorithms (5)
Other algorithms
DES; DES40; Diffie-Hellman (key agreement; key establishment methodology provides between 112 and 150 bits of encryption strength; non-compliant less than 112 bits of encryption strength); MD5; RC2; RC4
Tested configurations
- Windows Server 2003 Service Pack 2 (x86, x64 and IA64) (single-user mode)
