I don't know if anyone except me might need this, but I wrote a script that allows you to calculate how long one would need to crack a password of a specific length (depending on his hardware and number of different characters).

How to use:

Everything should be self-explaining up to Combinations per second. For this one you need to decide what hardware you want to check your password against and how fast trying one combination can be (which also depends on the algorithm).

I've googled for something AES related, but I couldn't really find anything (if you did, please post here). Instead there's a web page that lists how many keys per second video cards/CPUs can take when brute forcing the RC5-72 Algorithm, so go on and open that page in a tab.

As I am writing this, someone with a Radeon HD 4850-625 keeps the high score with 450951.8 kkey/sec (kkey/sec = thousand keys per second). So if I want to check a password against that card, I type below Combinations per second the number 450951800. For ten times that card, it will be 4509518000 and so on.

Have fun with that. Yes, Java Script required!

Pretty neat! Would you like me to mirror it on my server?

Sure, that would be nice

Here you go:

I added a quick line at the top crediting you.

I'm going to play around with this as soon as I figure out what my GTX 285 is capable of.

Cool, I'll add it to the start post!

EDIT: strange how the style gets slightly changed on omploader (see my screenshot). On your mirror I can see it like it was intended to be

Turns out I didn't think of leap years, as Adam told me. I've fixed the source code on my blog and will ompload the fixed version now. jwcxz's mirror however will be out of date until he fixes it.
