Recover password with known chars

[buka]

If that's all you know, the chance you'll be able to recover the password is... infinitesimal.

But yes, you can use a mask file instead of a single mask with masks containing " " and "9" in various places.

Code:

9 ?1?1?1?1?1?1?1?1?1?1?1
 9?1?1?1?1?1?1?1?1?1?1?1
9?1 ?1?1?1?1?1?1?1?1?1?1

etc
