Hi Alexander, I have introduced a few changes to raw-md5-kernel. Now we can achieve nearly 2700Mc/s with around 12k loaded hashes. Loaded 12906 password hashes with no different salts (Raw-MD5-opencl [MD5 OpenCL (inefficient, development use only)]) Press 'q' or Ctrl-C to abort, almost any other key for status Using kernel md5_ccc... 0g 0:00:00:01 0g/s 3258Kp/s 2202Mc/s 41219GC/s aaakiuzg..aaanukqh 0g 0:00:00:03 0g/s 3643Kp/s 3193Mc/s 41219GC/s aabfakxs..aabimaot 0g 0:00:00:05 0g/s 3698Kp/s 2555Mc/s 32975GC/s aabpjfwy..aabsuvnz 0g 0:00:00:06 0g/s 3725Kp/s 2661Mc/s 34349GC/s aabzsawe..aacddqnf 0g 0:00:00:07 0g/s 3744Kp/s 2737Mc/s 35330GC/s aackavvk..aacnmlml 0g 0:00:00:08 0g/s 3762Kp/s 2794Mc/s 36066GC/s aacujquq..aacxvglr More optimizations are possible if we could limit the key length to 16. Current key length limit of 55 seems to be unnecessary. This should free up some more registers and allow me to introduce few more bitmpas. Regards, Sayantan Content of type "text/html" skipped
