I'm working on an (long overdue) project for my security class - the assignment is to create a brute-force script that can generate a six digit password given a hint (ex. "1234") - the password can be lowercase letters & numbers.

Now my question:

Is there an easy way to script this in Perl using the matching/substitution functionality built into the regular expressions?

The issue I'm trying to conquer (w/ Java currently) is that the "hint" can be at any position within the string - I'm trying to write a recursive function but need to figure out how go through ever permutation given that not all of the characters in the string will be changing:

For instance, a six digit password with the hint "1234" will need to generate 1234xx, x1234x, and xx1234. The hint can be anything as long as it is shorter than the length of the password.

Any advice would be much appreciated!

Thanks!
