You are the Security Consultant working with a client who uses a lot of outdated systems. Many of their clients PC's still have Windows 98. You are concerned about the security of passwords on a Windo

DES is a symmetric encryption cipher used internally within the LANMAN algorithm, but DES itself is not the name of the overall Windows 98 password hashing scheme.

SHA (Secure Hash Algorithm) was not used for Windows 98 password hashing; it became common in later Windows authentication protocols like NTLMv2.

LANMAN (LAN Manager) is the legacy password hashing scheme used in Windows 95, 98, and ME. It converts passwords to uppercase, pads or splits them into two 7-character chunks, and then applies DES encryption to each chunk independently. This design makes it extremely vulnerable to brute-force and rainbow table attacks.

MD5 was not used by Windows 98 for local password hashing; it appears in other contexts such as file integrity checks and older web authentication schemes.
