oclHashcat-plus 0.071 crashes when using brute-force option

[LarryX]

Version: oclHashcat-plus 0.071
OS: Windows 7 64-bit
GPU: NVidia GTX 580

I am using the following command:
cudaHashcat-plus64.exe -m 500 mypasswd -a 3 -1 ?l?u?d?s?F ?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1

This runs fine, but as soon as I press the "s" key to see the status it crashes just after outputting the running time, for example:

Code:

s
Status.......: Running
Input.Mode...: Mask (?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1)
Hash.Target..: $1$aaaaa$bbbbbbbbbbbbbbbbbbbbbbbb
Hash.Type....: md5crypt, MD5(Unix), FreeBSD MD5, Cisco-IOS MD5
Time.Running.: 7 hours, 36 mins

The details of the crash are as follows:

Code:

Problem signature:
  Problem Event Name:    APPCRASH
  Application Name:    cudaHashcat-plus64.exe
  Application Version:    0.0.0.0

FYI, the dictionary attack mode does not crash when I check the status.


One follow-up question. How do you specify the password length when using the brute-force attack mode ? No matter what mask I put, it always outputs the following line:

Code:

Password lengths range: 1 - 15

One more thing. "cudaHashcat-plus64.exe -V" still shows 0.07 instead of 0.071.

I had the same problem when I used too many charsets

Thanks for confirming.

Just did some further testing and with a charset of ?l?u?d?s?F it crashes as soon as I specify a mask of 8 or more characters. While testing I noticed that the "Password lengths range: 1 - 15" only seems to be a cosmetic bug, assuming it should reflect the amount of characters in the mask.

For what it's worth, it also crashes with a charset of ?1 and a mask of 12 or more characters.

Yes and no. For example a mask length 16 can not display Password lengths range: 1 - 16 since oclHashcat-plus supports cracking only up to lenght 15.

Yes I noticed that. I initially had a mask of 16. The process starts just fine, but then I noticed that my GPU usage was around 0%. I think in a future version there should be an error message when someone tries to use a length of more than 15.

I'm obviously also hoping that the crash will be fixed at some point

You are absolutly right. I have already fixed it:

Thanks for reporting!
