Re: WPA support

They could have "passwords_check_last_interval / interval * 1.05 " that will make the numbers 5% higher than what they really are. Also there are ways to unknowingly do this like setting a timer for 500 ms and doing "passwords_check_last_interval / 0.500" I'm pretty sure Windows will over time have ...

Re: WPA support

Intel won't be supporting SSE5 because they are going with AVX which will have 3 operand instructions and 128 bit integer instructions and future versions will have 256 bit and 512 bit integer instructions.

Re: WPA support

What would they be faking? The numbers? Why only 11k on GTX260? A computer with two quad cores can almost get that (pretty sure). This is a rough estimate you can probably get 5,800 to 4,800 on a Core2 Quad 3.0 GHz. I forget if I took into account the fact that SHA1 needs 5 registers plus 1 temp reg...

Re: How high can you get

SSE3, SSSE3, SSE4a, SSE4.1, and SSE4.2 are not just for floating point operations but most of the instructions are pointless for cracking passwords. SSE3 (All the other instructions for SSE3 are for floating points): LDDQU - This is an alternative misaligned integer vector load. It can be helpful fo...

Re: How high can you get

I like the first image x4d3 posted. The one that is a total ripoff of BarSW including the error with the first three lines of boarders being white instead of gray. Well that and the fact that it is 1/2 the speed.

Re: Distributed crypo-network discussion

Yes, it will :-) We might have a command like option to limit CPU usage, for example leave 1 CPU core unloaded, or do not use CPU at all. It would be useful to have an option to specify the GPUs to use in multiGPU config, cuz somebody who have for example 8600GT & 8800GTS could use only 8800GTS, so...

Re: Tasks overview

The bandwidth for a distributed brute forcer is much less than the bandwidth for a distributed rainbow table generator. The distributed brute forcer is about the same as using AJAX to check if a user name is taken once every 10 minutes per client. The distributed rainbow table generator is about the...

Re: Which linux distributives to support?

Last question is still actual. If I am not using specific libs, can I expect binaries(not package, just .tar.gz of executables) to be compatible across linux types? (Debian/BSD/RedHat e.t.c.) For the most part yes. You may need to statically link somethings. A program I wrote I compiled on Ubuntu a...

Re: sha algos

Are sha-1, 256 and 512 are all main types of SHA? Yes, but you missed three SHA-0 , SHA-1, SHA-224 , SHA-256, SHA-384 , and SHA-512. Well SHA-0, SHA-224, and SHA-384 are less common. SHA-0 and SHA-1 SHA-1 fixed a weakness in SHA-0 by adding a bitwise rotation in the message schedule. SHA-2 family i...

Re: WPA support

Well I was getting my info from http://www.renderlab.net/projects/WPA-tables/ which is the first site for "wpa psk tables" in google. Hmm you do get a lot more sites with "wpa psk -rainbow tables" than "wpa psk rainbow tables." At least there are a good about of people that know the difference.

Re: WPA support

A few myths about WPA-PSK: * "WPA-PSK rainbow tables" are not rainbow tables they are lists of hashes for given passwords and SSIDs. * You never have a hash of the password. The hash of the password is just as good as having the password itself. Since you have two choices a password of 8 to 63 lette...
