good all character combinations using a given length

Question

Is there a program/tool/utility that would allow me to generate all possible character combinations (lowercase, uppercase, symbols, numbers) over a given length of characters (min-max)

Answer 1

This is essentially the same field as brute-force password cracking, which might be what you are trying to achieve. Wikipedia has a reasonable article on password cracking, and lists the most popular software for the task.

Answer 2

Thanks Colin, that's what I was looking for.
