Re: Alienware M17x - SLI GTX280m + 9400, only one GPU running

was thinking using VMware to install Vista and try but I am not sure if through a virtual machine
No that option is not yet avaliable for vmware, oh though I've heard talks that they are trying to support it.

Sounds like XP is going to be your only way to get it working.

Re: doubts on md5 cracking

so you mean that more than 8 characters it is a waisting of time Sorry I miss calculated earlier, 7 characters takes a little over 4 hours not 8. A length of 8 takes 17 days, a length of 9 takes 4.5 years. Unless you reduce the character count each time you increase the length. For example if you o...

Re: doubts on md5 cracking

:lol: Exactly! What do you mean "i have always doubted on those md5 crackers."? Since you know how many characters you used to - "created an md5 hash from" you can figure out how long it will take at most to find the plaintext from it. You can use my calculator - http://hashcrackers.thruhere.net/br...

Re: Alienware M17x - SLI GTX280m + 9400, only one GPU running

Try this, disable SLi and PhysX in the Nvida control panel then reboot. Then add the "LimitVideoPresentSources" to your registry you can read more about "LimitVideoPresentSources" by doing some google searches. Since you don't have a monitor output for each of your video cards this looks like your o...

Re: Alienware M17x - SLI GTX280m + 9400, only one GPU running

This is apparently wrong, because I am using my 8400GS without monitor attached in Win7 right now Doh! Maybe that was only with Vista 64. And I may have been wrong about the 9400 only getting 16M hashes/sec apparently I get about 35M at home. But the same card only gets 16M on another machine so it...

Re: Alienware M17x - SLI GTX280m + 9400, only one GPU running

Win 7 uses the new WDDM like vista does. It only supports video cards that monitors are plugged into. I would recommend that you down load the latest drivers from Nvidia if you haven't already. You may be able to enable physx on the 9400 to get it to be recongnized. There is an option in the nvidia ...

Re: HD 5870

I would go with...

Code: Select all

ighashgpu.exe -t:md5 -c:csd -min:8 hashlist.txt
min:6 might be to short to get a good average.

Re: Reversing the Last 7 Sub-Rounds of MD4

Sc00bz I didn't see that post.
Sc00bz - All you do is keep everything but the first 4 bytes in the password constant.
Well that explains why the first four bytes are the same when running ighashgpu. Also explains why you can't set the first four characters.

Reversing the Last 7 Sub-Rounds of MD4

For those that are into making bruteforce programs thought this may be an intersting article to get som more speed out of MD4 -
http://www.cs.rpi.edu/~zonena/papers/md4_v2.pdf has been shown to increase speed by 10%.

Montitor the file and remotely terminate the process (somehow) when the breakpoint is found. Haha nice! I suppose you could have the server check the output file periodically and when it see's the "breakpoint" hash it will execute a "pskill \\(client IP) ighashgpu.exe" to the client with local cred...

So does this mean that programmers can start programming for OpenCL and it will be supported by anything that supports OpenCL? Both ATI(once they support it) and Nvidia without rewriting the code?

Re: How high can you get

Since most bruteforcers support where to start from in the keyspace I agree with you, I actually thought about making a VB(only thing I know how to program in) program to do just that. This is were the problem comes in... Lets say you want to search for a password that is a minimum of 4 characters,...

Re: One more GPU hash cracker

That's the point. If you try to crack more than 10,000 salted hashes it would take too much time. So is your answer to run the 10,000 hashes through a dictionary attack and call it a day? "Oh to many hashes to try and brute-force, guess that's that." Even with 10,000 passwords running a batch of mi...

It's nice but 1 strong password would just need to long. And the others wont get cracked Well that kinda depends, the way I look at it is like this.

Re: Decrypting Hash Code

Yep it should be -h (your hash) -c (character set) -min_len (minimal password length). If you set the minimal password length to 5 it will start at length of 5 and continue up until it gets to max length of 15 or it finds the password.

By the way I sent you a PM.
