LAN Manager (LM) hashes use the DES (Data Encryption Standard) algorithm to hash passwords. Here's how LM hashing works:

The password is converted to uppercase and padded/truncated to 14 characters.

Split into two 7-character halves.

Each half is used as a DES key to encrypt a constant string ("KGS!@#$%")—resulting in a 16-byte LM hash.

CEH v13 Study Guide states:

“LM hashes use the DES encryption algorithm to create password hashes. Due to this method, they are highly vulnerable to brute-force attacks, particularly because they split the password into two 7-character blocks.”

Incorrect Options:

A: MD4 is used in NTLM hashes.

C: SHA is not used in LM.

D: SSL is a transport security protocol, not a hashing algorithm.
