[split] [split] oclHashcat v0.26 - not cracking ntlm hashes - exorcyst - 08-28-2011
I've found that if I have multiple hashes in the list, 64-bit .26 won't crack them. If I do one hash at a time they will crack.
There doesn't seem to be a problem with the 32bit version. I'm using NTLM hashes in this case.

RE: [split] [split] oclHashcat v0.26 - not cracking ntlm hashes - atom - 08-29-2011
first run looks fine for me. but the 2nd not, however the commands were the same. what do i miss?

32 bit vs 64 bit (2nd run)
RE: [split] [split] oclHashcat v0.26 - not cracking ntlm hashes - exorcyst - 08-31-2011
Can you confirm that you see the same problem on your end?

no,i can not reproduce it. can you please provide test_hash2.txt and 3tx3t.txt? maybe the problem is inside these files.
RE: [split] [split] oclHashcat v0.26 - not cracking ntlm hashes - exorcyst - 09-01-2011
I've enclosed the hashes, the first larger dictionary, the 2 small dictionaries that contain just enough to generate the 2 hashes I created, as well as a log of the 32bit working and the 64 bit failing to identify the hashes with the small dictionaries.
Note I'm using windows, I don't have a linux box running the dual cards. I have to operate using vmware so I run all my linux stuff under vmware and run windows 7 64-bit as the host OS, so I don't have the ability to test the linux version. I downloaded a fresh copy of the 0.26, verified the md5sum against the website and ran the tests again.
I'm using 280.26 drivers with dual gtx 570s

I have the exact same issue.
Env:
Linux 2.6.32-26-server #48-Ubuntu SMP Wed Nov 24 10:28:32 UTC 2010 x86_64 GNU/Linux
nVidia GTX 460 with nvidia-current 280.13-0ubuntu1~lucid~xup1

Hello Atom,
I will attempt to test the issue of multi-hashing with v0.26 using the ati platform(driver 11.7/11.9) on the following algorithms sha1, sha256 and md5 when a dcitionary is not in use on linux using the 64 bit binanry and see if makes a difference. If anybody beats me to it; kindly post the results here.
Based on the information above it appears that the previous user was running a 64 bit version of Windows 7 x64 using Nvidia GPU's.

since all regular oclHashcat features will be merged into oclHashcat-plus i will not longer try to debug this issue.
RE: [split] [split] oclHashcat v0.26 - not cracking ntlm hashes - chort - 10-20-2011
I suspect I'm having this issue as well. I knew there was something strange with trying to crack NTLM, but I couldn't isolate the variables. I'll try the 32bit version and see if that makes a difference.
