john cracks password files if I remember rightly.
md5 encoded password files don't look like that, they look like this
(not a real password line!)
You need to work out how to write that format.
>From memory: the "$1" bit means it is an md5 hash, the next
"$3nvOlOaw$" is the salt and the final "$vRWaitT8Ne4sMjf9NOrVZ." is
the md5 hash in some encoded format or other! Some googling should
reveal the correct algorithm!
