Date: Tue, 25 Aug 2015 15:03:28 +0300 From: Solar Designer <solar@...nwall.com> To: john-dev@...ts.openwall.com Subject: raw-sha256-opencl, raw-sha512-opencl, xsha512-opencl Claudio, magnum - The attached patch fixes the "max. length in index 1: wrote 55, got 55 back" self-test error seen after auto-tuning. I didn't test actual cracking with these formats after applying that patch - we should. Another known issue with these formats is that they implement on-GPU hash comparison using linear search. So when cracking a large number of hashes at once, they actually became a lot slower than what we had before (with computed partial hashes transferred to host). In a private e-mail exchange, Claudio said he'll eventually correct this. I am merely documenting it on john-dev since I am posting about these formats anyway.
