Post: Compiler for hashcat

Hi atom, I have just a few questions :-) What compiler are you using for hashcat (especially CPU version)? If you are using GCC, did you try also Intel compiler? In some cases it can produce much bet...

Just for completion, another possible options similar to #1 are: 4) (b & c) ^ ((~b) & d) 5) (b & c) + ((~b) & d) Results should be the same as #1, but who knows, lets try it :-D

OK, nice to see progress :), so we are attacking 10M/s, 1000M/s respectively ;) Here goes another thing connected with instruction amount reduction... If I'm not wrong, you are doing this in oclHashc...

Hi, sorry, i don't have much time now, so briefly another tip. Again, 'clever' compiler may optimize it for you, but your code doesn't look like compiler do the job well. First two steps of round ...

Hi Atom! I think that you can optimize MD5 algorithm a bit. Daniel Niggebrugge (EmDebr) nor Michail Svarychevski (barsWF) didn't reply me, so i'm trying you :) Here comes one of the optimization...
