Passwords

A password is a string of characters used to gain access to a resource.

Given the ASCII code, and n characters, you have various possibilities :

- uppercase or lowercase                  = 26^n combinations
- uppercase or lowercase + numbers        = 36^n combinations
- uppercase and lowercase                 = 52^n combinations
- ucase + lcase + numbers                 = 62^n combinations
- ucase + lcase + numbers + special chars = 95^n combinations (printable ASCII set)

Given a standard password of 8 characters, with all printable ASCII characters you'll have 95^8 circa 7 million billion combinations.

Password length should always be >= 8
