Cool. Thanks! > In case it's helpful, here're some benchmark figures of JtR running on SDE: Yes, can you show benchmarks before/after the addition of ternary logic instructions? And, did you fully make use of them (turning all of the 3-input basic functions of MD4/MD5/SHA-1/SHA-2 into single instructions) or only to define vcmov() for now? You should do both, so that we also have vcmov() available for use where it's sufficient (e.g., MD5's F and G) and in possible future code where we might not introduce proper ternary logic expressions right away. > BTW, SDE runs much more smoothly than I expected. At least those formats listed above ran quite fast on it. You mean the program's interactive response time, not the c/s rates. The c/s rates suggest there's pure emulation with no JIT. But that's fine for our purposes. Alexander
