I will add all those numbers to the performance webpage mentioned earlier. > And perhaps you can contribute some optimizations, too. ;-) The main optimization in Hash Suite is not in the "format" itself but in the key-generation and found matches process. This ideas can not apply easily in john without break support to many other options. But there some "things" that i was planing to add when i have some free time/supported hardware: 1- Eliminate in 32 bits version the use of 32 bits register. This improve performance in old CPU (when i wrote initially the asm) but currently i think it slow down performance. 2- Eliminate the full binary and only use partial (for table hash lookup). 3- AVX support. I think we need for this AVX2 with integer support. saludos, alain
