According to the blog: GPU Password Cracking – Bruteforceing a Windows Password Using a Graphic Card:
- A 5 character password can be cracked in less than a second with it.
- A 6 character password can be cracked in 4 seconds with it.
- A 7 character password can be cracked in 17 minutes and 30 seconds with it.
- A 8 character password can be cracked in 18 hours and 30 minutes with it.
- A 9 character password can be cracked in 48 days with it.
So what is a safe password?
No password is safe because computing is increasing and the timing required with the current hardware as shown above is astonishingly small and everyday faster GPUs and CPUs are being produced. However with above findings following deductions can be made so that password crack can be minimised:
- Increase the number of characters in your passwords
- Use alphabets, numbers and special characters
- Regularly change your passwords
Interesting. Only thing is that the author of that post inputs the length of the password into the cracking program. I bet it will take much longer to crack the password if you don't know its length. This is a much more realistic scenario. The cracking program will have to try a lot more combinations.
ReplyDeleteIrrespective of the character length the amount of passwords generated by IGHASHGPU with ATI 6990 is 9,820,521,128 / second in as it is shown in the screenshot above
