    Question Passwords, John The Ripper, etc.

    I need help concerning password cracking...i've downloaded John The Ripper to crack some (UNIX)-passwords but i noticed that the the dictionary file shipped with the program is rather limited and now i want to make my own dictionary. Hence i need a tool which will e.g. import two different wordlists and kill all the duplicates and spit out a new file.

    ummm, you are using unix? Try awk/sed. That has got to be the best tool out there.

    dictionary

    L0phtCrack has a good trial version out with a pretty comprehensive dictionary file. I would download the demo and steal the dictionary file out of it.

    By the way, it isn't password cracking, it is password "auditing." There is a BIG difference.

    Well, the difference lies in the legality of it ....

    If you are auditing passwords (i.e. you are doing this as part of your administrator job), then you are entitled to verify that users follow the password rules that have been set out in your IT policy.

    If you do not have rightful access to the password file (i.e. you are trying to get illegal access to a system) then you are cracking, which can potentially lead to criminal prosecution.

    Cheers,

    BrainStop> Thanks, couldn't have said it better myself

    sOnIc> Old, yeah, but it does still work. A password cracker is a password cracker. Kinda like the fact that Crack is still the best for *nix, and that one is even older. Then again, they did update it a few times.
