Where could I read more about that? LM hashes are split into two 0-7 lengths, 14char's maximum... and is Case insensitive (all uppercase) 1234567=0182BD0BD4444BF8AAD3B435B51404EE (LM) And 1234567hhhhhHH =0182BD0BD4444BF880F0CCFF038BF74 (LM) (cracked it would be 1234567 & HHHHHHH) Here are the two halves... 0182BD0BD4444BF8 880F0CCFF038BF74 NTLM on the other hand is case sensitive, so the same password would crack to the case sensitive version (1234567hhhhhHH) 66502AB0AEE4EDC749D62E91EF650C7B (NTLM) So if you see "NO PASSWORD" in a pwdump file it's because these hashes were present: 31D6CFE0D16AE931B73C59D7E0C089C0 (NTLM) AAD3B435B51404EEAAD3B435B51404EE (LM) Check the wikipedia for more: http://en.wikipedia.org/wiki/LM_hash http://en.wikipedia.org/wiki/NTLM -rich
