Question

Null Password Hash

I have a password hash (legally obtained-it IS legal to hack your own computer), and I want to crack it. However, Ophcrack failed to find the password, and an online LM hash cracker said that the hash was a "null". But I cannot logon with a blank password. Help?

Thanks in advance.

I am asking HOW TO CRACK IT AND WHAT IS WRONG WITH IT, NOT HOW TO RESET IT.

Then I can't help.

I've used the NTPASSWD to clear it then I login and change it to what I want. Sorry if that won't work for you.

Re: hash

In reply to: Irrelevant

I'm afraid that only the maker of the program you used to hash your password can tell how to crack it and what's wrong with it for the other programs you tried.

Since you didn't tell how you did it (no doubt it's legal to experiment with your own PC) nobody here can tell, even if we knew it when you had told (which is quite unlikely moreover).
