RIPEMD-160 http://www.esat.kuleuven.ac.be/~bosselae/ripemd160.html This is my implementation of RIPEMD-160. The pentium assember is a little off the pace since I only get 1050 cycles, while the best is 1013. I have a few ideas for how to get another 20 or so cycles, but at this point I will not bother right now. I belive the trick will be to remove my 'copy X array onto stack' until inside the RIP1() finctions the first time round. To do this I need another register and will only have one temporary one. A bit tricky.... I can also cleanup the saving of the 5 words after the first half of the calculation. I should read the origional value, add then write. Currently I just save the new and read the origioal. I then read both at the end. Bad. eric (20-Jan-1998)
