Just experiment with those functions. If you don't know the exact position of known hash fragment in those structures, just make those function produce some output and you will clearly see it. Please note, even if you get a password, its hash may not be equal to the hash of correct password (together with unknown part of the hash). ----- Original Message ----- From: "Turko" <granturko@...il.com> To: <john-users@...ts.openwall.com> Sent: Thursday, March 09, 2006 3:14 PM Subject: Re: [john-users] checking only first 5 characters of a md5 hash Thanks a lot. So the problem is that John must have a complete HASH to do his job? How can I complete it? Is it possible to solve my problem do you think? -- L'imbecille cade sulla schiena e si sbuccia il naso.
