    Question Password Cracker

    Does anyone know of a password cracker, that runs on windows, and cracks Unix/Linux password files?

    The reason why, is because, I would like to see how secure my password is for my website. If there isn't one that does that. How can I make a password on windows, and use a windows password cracker, to audit it?

    I think somewhere in the MISC forum was a post for a web based cracking utility that allowed you to enter the MS hash of your password.

    Edit: here it is

    As far as I would imagine, password complexity is just that...and not dependent upon operating system.

    Otherwise, L0phtCrack does have a trial version that does everything but brute force. I assume your password is at least going to pass the dictionary and dictionary+numbers attack that the trial does.

    I imagine that a password cracker could be on windows against linux/unix or you could run it on unix against your localhost. I don't use many of these tools. I imagine a brute force attack could eventually gain access (assuming the account does not get locked after x failed attempts).

    Try John the Ripper @ http://www.openwall.com/john/. It has *nix/win/dos versions and is considered to be one of the best password crackers around. There was an article on it today from Linux Security called "Psst... I know your password".

    This is an NT password cracker and I cannot speculate on its efficiency since the source code has not been released. I remember there were some doubts about this when the link to this was first posted at AO.

    John The Ripper is pretty cool with a huge dictionnary.

    I use L0PHT crack. Its pretty good but is kind of slow, if you look around you can get a copy for free. Search google or another search engine for the link to the site.

    Go here:
    http://www.evadenet.com/downloads/lophtcrack.shtml

    A direct d/l for lophtcrack.

    PS... Dooh! Nevermind. I had my head up my a*$ and did'nt pay attention to the question. Lophtcrack runs on Win32 or Unix/Linux. But it's used to hit Password Dumps and SAMS on Win32 platforms. You want to nail a *nix box from win. I can't read tonight. Somebody slap me before I post again...................
