Date: Tue, 5 Jun 2012 09:08:51 -0500 From: "jfoug" <jfoug@....net> To: <john-dev@...ts.openwall.com> Subject: RE: GPU formats vs Test Suite I made changes to the CPU version of cash-2 so that any salt > 19 is deemed invalid, and get 1410 hashes cracked, so I believe 1410 IS the correct value. Also, from memory, 1410 was the 'right' value, as long as the input file had not changed. This was the count I 'was' getting with the CPU version, prior to when I rewrote it. It used to have a 19 char salt limit. So if 19 char salts will be the max used in the opencl, then simply change this line in the jtrts.dat file: (opencl)(gpu),(X),(jumbo)&(opencl),50,mscash2-opencl,pw,MSCash2_tst.in,mscas h2-opencl,Y,X,(1500),(1500) To this: (opencl)(gpu),(X),(jumbo)&(opencl),50,mscash2-opencl,pw,MSCash2_tst.in,mscas h2-opencl,Y,X,(1500)(1410),(1500)(1410) NOTE, I left the 1500 count, just in case you later update the format, and allow 22 byte salts. Having the 1500 there will not impact current running. If the ts finds either 1500 or 1410 being cracked, it will allow it to be passed. Jim. From: SAYANTAN DATTA [mailto:std2048@...il.com] So I increased the MAX_SALT_LENGTH to 23 to avoid buffer overrun and also decreased PLAINTEXT_LENGTH to 31. Now it is guessing 1410 passwords. other 90 passwords can't be cracked by my due to the salt length issue. Any reason why reducing the PLAINTEXT_LENGTH increses guessing?? Previously it was set to 40. Content of type "text/html" skipped
