Solar beat me to completion by releasing J4 before I finished all I was working on. The Jumbo-4 patch does get these md5gen sub-formats 'working' in x86-64 builds. It does this by setting a flag that FORCES md5-gen to not use SSE instructions (only for x86-64 builds) on the priorly broken sub formats. Once it is forced back into 'generic' OpenSSL type mode (usually does not use OpenSSL, btw), the code worked fine. However, any performance benefit of the SSE enhancements were lost. However, I have found the problem, and correctly fixed it. Now, these subformats work correctly AND utilize SSE2i on linux-64 builds. There are also many more changes / improvements. Thus if a user wants better performance, they can obtain jumbo-4 today, and apply a few patches from the wiki pages, and get this performance. However, it is likely that a jumbo 5 will be out shortly that incorporates all of these changes into a single jumbo build. The patches can be found: http://openwall.info/wiki/john/patches NOTE, there is also a new John-Test-Suite (v1.05). It is always good to test your john build, to make sure it actually will find the hashes it claims to be able to find.
