What I was done last week is : 1) I read papers you recently posted. And I emailed author of qhasm-cudasm for requesting the tool. 2) The bitslice implementations of SHA-256 or SHA-512 on GPUs are worth discussing. I read your bitslice implementation of MD5. It takes advantages of sse2 to compute MD5 hashes at one time. Now raw-sha256-cuda implementation already use SIMD and/or bitslice. I tried use more threads(than now just 1) to compute one hash. However, the data dependence make it hard to implement. I am looking forward ideas of optimization. 3) As you suggested, I am starting write DES format on cuda. I will make another post to track my progress and clarify questions on it. Thanks! Dongdong Li Content of type "text/html" skipped
