Now, this is not jumbo-5, but I did not think anything changed about how md5_gen is built, since then. $ ../run/john -test -form=md5-gen Benchmarking: md5_gen(0): md5($p) (raw-md5) [SSE2 16x4x2 (intr)]... DONE Raw: 9653K c/s Benchmarking: md5_gen(1): md5($p.$s) (joomla) [SSE2 16x4x2 (intr)]... DONE Many salts: 8321K c/s Only one salt: 5404K c/s Benchmarking: md5_gen(2): md5(md5($p)) (e107) [SSE2 16x4x2 (intr)]... DONE Raw: 5404K c/s Benchmarking: md5_gen(3): md5(md5(md5($p))) [SSE2 16x4x2 (intr)]... DONE Raw: 3788K c/s Benchmarking: md5_gen(4): md5($s.$p) (OSC) [SSE2 16x4x2 (intr)]... Wait... Session aborted I will later check this on my pen drive linux-64 system, to see if there are problems showing up there, which do not appear on this 32 bit build. Jim.
