So here is a patch that uses a similar implementation, but for the whole freebsd MD5 crypt(). It is set to use ICC, so you might want to download it (it speeds everything up anyway) to test, but it should be possible to have it run on gcc (don't forget -march=nocona). The patch is against john-22.214.171.124-all, not vanilla! (it should work with vanilla anyway) It is REALLY ugly (more than my usual production ...), and I only tested the -test function, 32bit mode, so it might not work at all in the real world. Bench with standard code on my laptop: 3258k/s With this code: 10433k/s This MD5 code could hash around 15M k/s on my laptop, compared to 19M for BarsWF. But he can use the "reverse trick" and save 25% of the calculations, so the two implementation are in the same league. Have fun with it! PS: next stop, GPU implementation. I'm getting tired of not cracking enough of these hashes. -- To unsubscribe, e-mail john-users-unsubscribe@...ts.openwall.com and reply to the automated confirmation request that will be sent to you.
