A very special mask

[R4ms3s]

Hello everybody !

So i've a very specific request.

I need a mask that do these thing:

- the password is 8 chars uppercase (ok i know that: ?u?u?u?u?u?u?u?u).
- The passwork have max two time the same letter.
- if the password contain two time the same letter, they are never next to the other.
- the password nerver have the same 2 or more letter sequency (ABCDEFAB doesn't work because AB is repeted).

If someone here can do something like that (without hundreds lines of code) then this is a genius.

Thank you everybody.

You'll want to use

http://thesprawl.org/projects/pack/#policygen

.. but that will only solve most of your question, not the "no repeated characters" part.

But in practice, most hashes are fast enough that this can be ignored.

[Edit:]

Read too fast - I see that most of your concern is about duplicated/repeated letters.

PACK won't help with this, because generating masks that did this would be prohibitive. You're better off with a custom external script to generate candidates.
