Subject: Johnny's "Guess password" button

Hi list

How does "Guess password" work? Does it use john at all? There is no
sign of it in the console log. Were there any plans of adding similar
function to john? I mean e.g.:
$./john --guess=foo ...

instead of something like this:

$ echo foo|./john --stdin ...


$ echo foo > single_word
$ ./john --wordlist=single_word ...

It would be easier to use rexgen with alphabet like this:

$ ./john --guess=624686 --regex=alpha:T9='\0' --stdout

instead of:

$ echo 624686 | ./john --stdin --regex=alpha:T9='\0' --stdout

or even;

$ ./john --regex='[mno6][abc2][ghi4][mno6][tuv8][mno6]' --stdout

Instead of applying regex mode, it could be hybrid mask or word mangling
rules (just like for wordlist mode).

Best Regards,
Marek Wrzosek
