Which is more secure an LM hash or an NTLM hash?

Answer 1

NTLM Hash is more secure than LM Hash. It was actually replaced by Windows with NTLM. NTLM is case sensitive; so it matters how passwords are typed, its character set is 65,535, and it does not limit stored passwords to two 7- character parts. NTLM is considered a much stronger hashing algorithm. Just make sure passwords stored are more than 14 characters and you will be fine. Now Unix and Linux are probably a more stable OS because they use "salt" Windows LM and NTLM does not.
