#1 suuport for hybrid attacks: pattern matching

[Nitin Diwaker]

Kudos for a great program; I dont think even
professional tools can recover the passwords out of 128
bit user password encrypted files.

One feature that I would like to see in the program is
that when a user is aware of the format of password,
for e.g. 4 digits followed by 4 lower case aplhabets.
Now this may be represented in Regex form as:
(0-9)\4(a-z)\4 (Not too sure if the expression is correct).

I am not too familiar with C, however I am pretty good
at JAVA, in case you iwsh I might join the project to
create a GUI for the application.

I have been thinking of this and it is in the TODO (right
between Masked passwords and real permutations) ;)

The big question is really how powerfull one should make it
and the next is how much we should care about sorting out
unique patterns when (or maybe if, but I guess it is a when)
we support feeding it with several different patterns to try.

I will look into this when I get the time but if you want to
get your hands dirty I welcome any help. As I wrote in the
TODO, John The Ripper could be an inspiration for the
permutations as that tool has a powerfull patternengine we
might be able to use.

A GUI would be great and as it is something that I really
think is dead boring to do the only way to get a GUI will
probably be to write it yourself :)
I will gladly help with questions and incorporating it and
it's developers in the project though.
