Message-ID: <4D66F82B.6030407@bredband.net> Date: Fri, 25 Feb 2011 01:30:35 +0100 From: magnum <rawsmooth@...dband.net> To: john-users@...ts.openwall.com Subject: md5_gen(0) broken for ages? After applying the intrinsics fixes, raw-md5 is broken for me. It claims there are a number of salts (for tens of thousands of hashes, it claimed some 190 salts, for 10 hashes, it claimed 9 salts... maybe something uninitialized?). And, probably as a consequence of this, it's AWFULLY slow (while the benchmark show almost a 2x speedup). It does crack stuff correctly though. I tried all sorts of things, like adding the tag "md5_gen(0)" to the hashes in the files they resided. I also tried adding a $ (or $: or ::) in the end of the hash or using a file with nothing but the hash (no username, no colons, just the hashes). Nothing make any difference. Then I started reverting. This is not new at all. The oldest JtR I have on disk (1.7.6-jumbo7) have this bug. It's just that until now, we have been using the separate raw-md5 format so no-one has noticed md5gen(0) is broken. Or is it just me? This is on AMD x64 as well as Intel x64. Compiling with clang made no difference. magnum
