Right now I am going through the DES BS code. Have you compared your code to openssl implementation (which is not bit sliced)? How much speed up has it given? I ran the test on my system, for DES I have following result. I could not understand the meaning of the result, I mean how you calculate c/s, what is real/virtual and how to relate c/s to encryptions/sec. Benchmarking: Traditional DES [32/32 BS]... DONE Many salts: 439104 c/s real, 1514K c/s virtual Only one salt: 433184 c/s real, 1353K c/s virtual Thanks Deepika On Tue, Apr 3, 2012 at 9:21 PM, Solar Designer <solar@...nwall.com> wrote: > On Tue, Apr 03, 2012 at 08:51:14PM +0530, Deepika Dutta Mishra wrote: > > I would like to contribute to your work if you require, since bitslicing > is > > what i am focusing on if you have any requirement in it I would like to > > contribute, this will help me also in mastering this technique. > > We had a discussion on this very list with Piyush Mittal regarding > changing more of the JtR "formats" to use the bitslice DES > implementation.
