After padding, the LANMAN hash is divided into how many parts, and what are their sizes?

• A. Two four-character parts
• B. Three seven-character parts
• C. Four six-character parts
• D. Five five-character parts

Answer: (B)

The LANMAN (LM) hashing process pads the password to a fixed length, then splits it into two equal halves. Specifically, the password is uppercased and padded to 14 bytes, which yields two 7-character halves. Each half becomes a DES key and is used to produce an 8-byte DES encryption result; the final LM hash is the concatenation of those two results, totaling 16 bytes. So after padding, it’s divided into two parts, each seven characters long. The notion of three seven-character parts would not align with the 14-byte total that splits into exactly two halves.
