Hello Hashcat-Users!

I am very proud to present you oclHashcat-lite v0.07. You can download it here.

Highlights:

Full support for mixed GPU types due to own thread management.
NVidia kernels has been vectorized - gave nice GPU utilization boost.
Improved DES kernel, more than 20% performance boost on AMD cards.
Broke 20B/s mark on stock clocked hd6990 @ MD4.
Switched to AMD APP SDK v2.5.
Added kernels for nsldap, nsldaps, MSSQL(2000), MSSQL(2005) and Cisco-PIX MD5.
Rewritten --restore code from scratch. It is much more intuitive now.
Parameters for distributed computing simplified.

NVidia driver notes:

Nothing special here. Everything should work out-of-the-box.

AMD driver notes:

Starting with this version, Catalyst v11.11 is the new recommended driver version.

Nothing to worry, even if oclHashcat-plus has not been updated yet, it will continue to work fine.

Linux users benefit from Catalyst v11.11 for two more reasons:

The 100% CPU killer bug problem is fixed.
It finally ships with an embedded OpenCL runtime. In other words: no more need to install the AMD APP SDK.

Important: You have to uninstall the AMD APP SDK v2.4. Then, after uninstalling the SDK, make sure the correct libOpenCL.so is loaded (the one which ships with the driver). You can verify this by doing an "ldd oclHashcat-lite64.bin" and check the path. It should link to "/usr/lib/libOpenCL.so.1". If it is not found, you may have to create an symlink from "libOpenCL.so" to "libOpenCL.so.1". For some unknown reason the Catalyst installer did not do this automatically on my box.

Great news! Thank you and keep up the fantastic work Smile

P.s.: YAY you broke the 20B/s mark @ MD4 on an AMD card!!! Big Grin
