I've created new alphabet in john.local.conf:
[List.Rexgen.Alpha:reverseT9]
0=[\ 0]
1=[1]
2=[abc2]
3=[def3]
4=[ghi4]
5=[jkl5]
6=[mno6]
7=[pqrs7]
8=[tuv8]
9=[wxyz9]
(I've added digits at the end, so the outputs of all following commands
will be the same.)
To use it, I need this:
$ echo 624686 |./john --stdin --stdout --regex=alpha:reverset9='\0'|grep
magnum
Using default input encoding: UTF-8
Press Ctrl-C to abort, or send SIGUSR1 to john process for status
magnum
4096p 0:00:00:00 0.00% 34133p/s 624686
or create wordlist with only one line:
624686
and use wordlist mode with regex.
The easiest way with using rexgen is something like this:
$ ./john --stdout --regex='[mno6][abc2][ghi4][mno6][tuv8][mno6]'|grep magnum
Warning: regex mode currently can't be resumed if aborted
Press 'q' or Ctrl-C to abort, almost any other key for status
magnum
4096p 0:00:00:00 0.00% 25600p/s 624686
It's impossible to use regex with alphabet as standalone mode. Or am I
doing something wrong?
