Comparing Cracking Speeds

4 posts in this topic

I've been working on building a BruteForce Password Cracker in C#. I've managed to max out at about 360,000 attempts per second for MD5. I'm trying to compare this to other password crackers such as JTR. I'm well aware that JTR is much more efficient seeing as how it's written in C, but when I had JTR do a benchmark test on my computer, and it said that the FreeBSD MD5 was at 5,500 c/s. From what I've read, the FreeBSD MD5 is much slower than regular MD5. Unfortunately I can't find an implementation in C#.

So I'd like to find out how my Cracker compares to what else is out there. Most of the articles on the web about Password cracking are about ten years old, so there estimates are out of date.

Thanks,

MD5 is 128bit?

even 360k/s is a no go i'd guess?

As I suspected, working in C# is bound to slow things down considerably.

Could you give me an estimate on how many c/s a good cracker would have? Not one of the ones that can run off a graphics cards, but on an average desktop computer.

EDIT: Whoa, I'm starting to see what you mean. I ported my code over to C, and I'm getting over 2.7 mill c/s. Big difference. Is that about what the average is, or should I be expecting to see more?

Thanks,

you might want to try using gpu's as cracking utilities, just an idea, ik that there are already a few programs out there, but none of them fully support a large range of diff cards.
