What specific transformation does LANMAN apply to passwords before hashing?

• A. Converts to uppercase
• B. Converts to lowercase
• C. Keeps case unchanged
• D. Uses a salt

Answer: (A)

LANMAN pre-processes a password by converting it to uppercase before hashing. This makes the resulting LM hash case-insensitive and is a defining part of how the algorithm operates. After uppercasing, the password is padded or truncated to a fixed length and then processed further to produce the hash. Because it does not apply any salt, and because lowercase, unchanged case, or other transformations aren’t used in this pre-processing, the correct description is converting to uppercase.
