multi.hccap miss password and benchmark -m 3200 display driver stopped responding
#1
1. multi.hccap miss password
I merge 42 hccap files together and crack,oclhashcat v1.00 find 39 passwords and 3 fail,but 42 passwords all in the wordlist. Use winhex to check them , hex values no problem , hccap file quality is not the reason of this problem.
A = A.hccap
B = B.hccap
C = C.hccap
D = orther (one hccap file)

single hccap : A or B or C found
multi hccap : merge A+B or B+C or A+C found
multi hccap : merge A+B+C found
multi hccap : merge 42 hccap files 39 found (A B C not found)
multi hccap : merge A+B+D or B+C+D D found (A B C not found)
multi hccap : merge A+D or B+D or C+D D found (A B C not found)

2. benchmark -m 3200
OS : win7 64bit
GPU : HD 5750
driver : 13.8beta or 13.9
command : oclHashcat64.exe -b --benchmark-mode=1 or --benchmark-mode=0 -m 3200
every time when test Hashtype: bcrypt, Blowfish(OpenBSD) ,display driver stopped responding and has recovered. Test looks like stop.This problem only happen in benchmark mode.

Hey and thx for your testing and the report.

I don't really like to discuss 2+ different problems within the same thread....

Anyway,
1. please open a trac ticket https://hashcat.net/trac/ with a set of *minimal* hccap files (for instance this one: multi hccap : merge A+B+D or B+C+D D found (A B C not found) ), add those files in a 7z archive and attach it to the trac ticket.
Please make sure that the cap/hccap are self generated and do not contain any sensitive info (i.e. please make captures w/ fake ESSID / BSSID / non-sensitive passwords)

2. it could be, since you use windows, that you didn't apply this patch: http://hashcat.net/wiki/doku.php?id=timeout_patch and/or GPU cooling is not done (correctly).
Furthermore, bcrypt is a slow and demanding algo, therefore it is very likely that w/o the reg patch etc... since driver does not respond in time, you see the crash. If not you need to do further test, when exactly it crashes...

I recheck them again, A B and C are wpa ,the other are wpa2 ,as you said. wpa is HMAC-MD5 ,wpa2 is HMAC-SHA1.Thx philsmd.
