Attacking only one hash, I get wonderful figures (I am exhausting inc:digits in both cases): $ ./john-jumbo12E1-intr test.hash -fo:raw-md5 -inc:digits Using raw-md5 mode, by linking to md5_gen(0) functions Loaded 1 password hash (Raw MD5 [gen]) guesses: 0 time: 0:00:00:09 c/s: 12196K trying: 83536056 - 83536784 $ ./john-jumbo12E1 test.hash -fo:raw-md5 -inc:digits Loaded 1 password hash (Raw MD5 [raw-md5 64x1]) guesses: 0 time: 0:00:00:22 c/s: 4936K trying: 83536787 - 83536784 That's significantly better than 2x! Kudos to anyone involved. magnum
