I just implemented this and posted to the wiki at http://openwall.info/wiki/john/patches (patch 0027). You may like the 0012 patch too. Both are somewhat experimental - I'm not sure they will stay as they are in next Jumbo. Sample output: $ rm -f deleteme && ./john -pot:deleteme -inc:alnum ~/src/john/john/test/NT_tst.in -fo:nt -crack-status Loaded 1500 password hashes with no different salts (NT MD4 [128/128 X2 SSE2-16]) 1 (u8-NT) guesses: 1/2352000 time: 0:00:00:00 0.00% c/s: 26133K trying: 0101535 - 0103682 start1 (u54-NT) guesses: 2/9835008 time: 0:00:00:00 0.00% c/s: 75653K trying: marier - mang96 test (u10-NT) guesses: 3/26133248 time: 0:00:00:00 0.00% c/s: 145184K trying: tech - ting summer (u37-NT) guesses: 4/36863744 time: 0:00:00:00 0.00% c/s: 194019K trying: summit - sumpoo johnny (u39-NT) guesses: 5/91389952 time: 0:00:00:00 0.00% c/s: 365559K trying: john75 - joha99 12345 (u28-NT) Note 1: Applying only patches 0012 and 0027 to a 1.7.8-jumbo-7 tarball should work fine, ignore the warnings when patching. Note 2: The figure is not words tried, but word/hash combinations tried. So in the output above, it actually made the first correct guess somewhere around 2352000/1500 = candidate number 1568. This can be a bit confusing. magnum
