Password Recovery Speeds

Now this is an interesting analysis of password recovery speeds. It compares password length and chars used to the time different computers need to bruteforce the password, ranging from Class A (speed of a pentium 100) to Class F (supercomputers, large scale distribution) computers.

They take a look at passwords that consist of only numbers, only letters, a combination of numbers and letters and finally letters and numbers and common symbols. For example a six digit password could be cracked by a Class A computer in about 9 hours while a Class F one would reveal the password in the same instance you started the process. Take a look and calculate how long it would take that someone could bruteforce your passwords.

It´s of course a different story if something prevents the bruteforce process to continue, for example online banking accounts disable the account after three failed login attempts.
