Exam CEH-001 Topic 12 Question 415 Discussion

The LM hash is computed as follows.
1.The user's password as an OEM string is converted to uppercase.
2.This password is either null-padded or truncated to 14 bytes.
3.The "fixed-length" password is split into two 7-byte halves.
4.These values are used to create two DES keys, one from each 7-byte half.
5.Each of these keys is used to DES-encrypt the constant ASCII string "KGS!@#$%",
resulting in two 8-byte ciphertext values.
6.These two ciphertext values are concatenated to form a 16-byte value, which is the LM
hash.
The hashes them self are sent in clear text over the network instead of sending the
password in clear text.
