The suite contains SHA-224, SHA-256, SHA-384, and SHA-512. Each algorithm is represented by the length of its output. SHA-2 algorithms are more secure than SHA-1 algorithms, but SHA-2 has not gained widespread use. LANMAN: Microsoft LANMAN is the Microsoft LAN Manager hashing algorithm. LANMAN was used by legacy Windows systems to store passwords. LANMAN used DES algorithms to create the hash. The problem is that LANMAN’s implementation of the DES algorithm isn’t very secure, and therefore, LANMAN is susceptible to brute force attacks.
10 Network Policy Server. 10, is accessed from the Start Menu | All Programs | Administrative Tools.

TACACS+ TACACS is the Terminal Access Controller Access control System. TACACS is a remote authentication standard. TACACS is used for dial-in and network access. The original TACACS standard was mostly used in UNIX systems.
Some common hashing algorithms include MD5, SHA-1, SHA-2, NTLM, and LANMAN. MD5: This is the fifth version of the Message Digest algorithm. MD5 creates 128-bit outputs. MD5 was a very commonly used hashing algorithm. That was until weaknesses in the algorithm started to surface. Most of these weaknesses manifested themselves as collisions. Because of this, MD5 began to be phased out. SHA-1: This is the second version of the Secure Hash Algorithm standard, SHA-0 being the first. SHA-1 creates 160‑bit outputs.
