That is why the ‘regen-salt’ is so nice.   It rebuilds a ‘valid’ hash once found.  For a long time, I had used other techniques for finding lost salts, and yes, the editing after the fact to get the right hash/salt and the ‘real’ password was a pain.  That is why I built code to automate that in JtR.   


It will ONLY be useful for tiny very undersized salts (like original DES was, like early media wiki, etc), and it sounds like this is an ideal candidate (100 salts).

It' ll definitely do, but what I dislike in this technique is the need to cleanup the .pot file due to the fact that salt and the pass will be combined.

I've noticed that just appending ^[0-9] ^[0-9] to the dictionary rules make the job.

Wouldn't it be easier to implement a kind of "macro" parameter that allows a user to specify a rule or a set of rules to add to every rules? (i.e. john --macro-rule="^[0-9] ^[0-9]")
