Try a success rate of 99.4% and 4 tables.

News:

I'm making significant progress on the OpenCL rainbow table code, including fixing a few subtle bugs and making it compile cleaner.

:)

I'd expect another beta out soon-ish, and hopefully it will include all platforms. I've got Linux & OS X working, just need to hammer Windows into shape.

And Windows is pretty much set - just a few things left to finish for the builds.

Also, GRTCrack-OpenCL will be using the curses interface instead of the debug interface.

I've hammered down a ton of OpenCL issues, and right now the kernels are compiling & running properly with:
- AMD OpenCL
- nVidia OpenCL (why? I've got CUDA support...)
- Intel OpenCL
- Apple OpenCL

The one major limit right now is that I only support one device in cracking. I'll add other devices soon, but it's complex enough for now with one.

Ugh.

The code is, in theory, done.

It's just miserably failing to find things with the ATI SDK.

So, either I have a bug in my OpenCL code that's pretty bad, or the ATI SDK later than 11.4 has bugs.

Either is possible...

Hm...

Works fine on single hash mode.

Fails with multiple hashes.

Good enough for another beta. :)

Expect a release this weekend...

Oh, and I've got a very, very spiffy new feature. ;-)

woo boy. Definite bugs to fix... I'll be honest, I don't know how some of this stuff actually generates *any* results right now. Doop de doo...

//EDIT: Oh, right, little endian values. Woo. :) They are sorted.

*codes away furiously*
