What hash type does that "slow" password file use? What hash type is prevalent in your pot file? What version of JtR (and any patches) do you use? My guess is that you're dealing with saltless hashes, and that the corresponding *_fmt.c file (coming from a patch) does not provide proper binary_hash() functions. If so, you may consider improving that *_fmt.c file and/or you may use the workaround suggested in this posting: http://www.openwall.com/lists/john-users/2008/02/04/3 The piece of code quoted in that posting is normally very fast, but it becomes very slow under conditions mentioned above. If so, it may be dropped (commented out) with little harm.
