What is the algorithm used by LM for Windows2000 SAM ?

A.
MD4

B.
DES

C.
SHA

D.
SSL

Explanation:
Okay, this is a tricky question. We say B, DES, but it could be A "MD4" depending on what their asking – Windows 2000/XP keeps users passwords not "apparently", but as hashes, i.e. actually as "check sum" of the passwords. Let’s go into the passwords keeping at large. The most interesting structure of the complex SAM-file building is so called V-block. It’s size is 32 bytes and it includes hashes of the password for the local entering:
NT Hash of 16-byte length, and hash used during the authentication of access to the common resources of other computers LanMan Hash, or simply LM Hash, of the same 16-byte length. Algorithms of the formation of these hashes are following:
