As evident from the site of john the ripper, JTR example, john can be used for finding password form a unix machine passwd file.

can JtR be used to crack password of a password encrypted word file? I know there is another utility by openwall which does the same...

  • $\begingroup$ I'm closing this as off topic for the moment - we don't really handle "what can I do with this tool" - for topics that are on topic, have a nosey at the faq. I've talked to some potential sites about migration; if you have a specific problem you you're interested in understanding if John the Ripper can help with, do feel free to edit the question and flag it and then they'd be happy to have it - there's an edit link under your question and a flag one too :) $\endgroup$ – user46 Mar 20 '12 at 10:00

  • $\begingroup$ @Ninefingers: can you migrate this to security.SE?? or should i repost it? $\endgroup$ – Vineet Menon Mar 20 '12 at 12:10
  • $\begingroup$ @VineetMenon I can migrate it, but I did ask them and I think they'd want it focusing on a more specific problem first :) But when you're done with editing, yes, can migrate no probs. $\endgroup$ – user46 Mar 20 '12 at 12:55
