Unfortunately, packagers tend to unnecessarily modify default settings, file paths, etc. My recommendation is to build JtR from the source tarball - or to use official packages such as JtR Pro or the "john" package on Owl. ;-) > I picked the wrong one when I made my changes.

The asterisk character is not any special, and it is not the reason why the normal wordlist rules failed to find your case permutation for that password - rather, it's that the case permutation was too unusual: > Real Password: > As*od3U8 > Now I'm trying to write a script to swap back and forth between the normal > and NT wordlist rule set in the john.conf file so I can LM hash, and then NT > hash the resulting set.

There's no elegant way to do that within a single install of JtR, sorry. You might try using two installs, in different directories. -- Alexander Peslyak <solar at openwall.com> GPG key ID: 5B341F15 fp: B3FB 63F4 D7A3 BCCC 6F6E FC55 A2FC 027C 5B34 1F15 http://www.openwall.com - bringing security into open computing environments Was I helpful?
