There's not much to say in terms of error message. This error occurs if the self-test hash was not cracked but it should be cracked. That's all we know.

    Thread: hashcat finds cpu but not gpu
Post: RE: hashcat finds cpu but not gpu

Typically the nvidia driver should install it's own opencl runtime, but for some reason it did not. Another question is why is there an AMD opencl runtime detected. Maybe the computer had an AMD GPU i...

    Thread: Locating bottleneck in Brain
Post: RE: Locating bottleneck in Brain

A good rule of thumb is that if you have more than 500kH/s of total performance (all OpenCL devices), hashcat brain (even running on a very fast system) will create a bottleneck. Another rule to add i...

The high CPU use on startup is because of the kernel compilation. This is done by the opencl runtime which is provided from the opencl device driver. It creates some initial CPU load only for a short ...

There's no way to reproduce this if you do not attach files to do so.

    Thread: Crackpos incorrect
Post: RE: Crackpos incorrect

The password output given by hashcat is based on the crackpos. IOW, if the crackpos is wrong, the password is wrong, which is not the case. If you want to know more about the details, see here: htt...

Yes, per salt. But salts are always known, otherwise the original authentication system can not do its work either.

Don't forget to -O, with a mask of length 11 you will get a drastic performance increase.

    Thread: Crackpos incorrect
Post: RE: Crackpos incorrect

You cannot measure the efficiency of the attack based on crackpos as this is a parallel execution with millions of workitems in it. It is up to the OpenCL runtime which one to execute in which order.

Converted wordlist can't work in optimized mode or only up to 6 character passwords in pure mode. The only way to crack this is to write a separate hashcat kernel. Expect raw sha1 performance and divi...
