Attached are two external mode definitions. (For others on john-users:
these are trivial customizations of the KnownForce mode.) Combined,
they implement all variations of the exact pattern you mentioned above.
You need to append the attached text file to your john.conf file. You
may do so with a text editor, or you may run the command:
cat KnownWilliam.txt >> john.conf
(Note: with _two_ greater-than characters in a row, or you'd end up
_overwriting_ the file rather than appending to it. Please be careful.)
Then run John with:
./john -e=KnownWilliam1 PASSWORD-FILE
and then with:
./john -e=KnownWilliam2 PASSWORD-FILE
where PASSWORD-FILE is the filename of your password hash file. Each of
these commands will take less than a minute, and one of them ought to
crack your password. If not, despite of you doing things correctly,
then your description of the password pattern above does not match your
actual password being attacked.
Please let us (the community) know whether this worked or not. If not,
then please describe what exactly happened and how long it took (to
confirm that you were doing things correctly). Preferably copy & paste
the relevant commands and output from your Terminal. Also suggest how
to relax/broaden the pattern.
