More precise set of characters for password recovery

[dkdlv]

Hi!
On the same idea to improve the password finding ( #72 ), is it possible to find a way to give a more precise set of characters?

Maybe on the way John let us give a regex: in my case, I am seaching an uppercase hexadecimal string so being able to give something like that in entry [A-F0-9] should be more efficient on long passwords.

Thanks!

Hi,
You can specify characters to use by listing them explicitly. Using predefined character sets such as ?p, ?l, etc is not mandatory. In the case of uppercase hexadecimal digits, you can use 0123456789ABCDEF, or in short ?dABCDEF as the character set.
Being able to use a regex could be nice especially once masks are supported (#55), but it will take me some time to implement it.

For the record, a similar question was asked in #78.
Maybe this deserves some more documentation or a more detailed example in the tutorial.
