Post: RE: oclhash question about length
use --increment, see https://ob-security.info/?p=116 too. my recommendation: do not try to crack passes < length 4 using oclHashcat

The SDK v2.3 is absolutely useless. I can't express how disappointed I am. ATI developers have confirmed, and known about all of the bugs for some time, with adequate time to fix them. But no...

Post: RE: AMD Stream 2.3 SDK released
i did not use clc. i use the GPU_DUMP_DEVICE_KERNEL environment variable. if defined it dumps the .il and the .isa when its execing a opencl kernel.

Post: RE: AMD Stream 2.3 SDK released
yes, i totally agree on that. but what i orginally wanted to say is that it is not "enough" to have C compiled to IL using clc since there is no BFI_INT instruction in IL and thats why i used the GPU_...

    Thread: multihashing of sha1($salt.$pass) possible?
Post: RE: multihashing of sha1($salt.$pass) possible?
sorry, but this does not work with oclHashcat for two reasons: 1. you can not add salts or charsets in hex 2. you can not crack plains of size 15 or bigger and you need 24

    Thread: different attack types
Post: RE: different attack types
absolutly not. for example if you limit the attack to --perm-min=8 and --perm-max=8 it will only use words of length 8. N! function of 8 = 40320. so it requires 40320 * number of words (with length 8)...
