If you just want to get started try a different hash mode. The iTunes backup >= 10.0 is the slowest algorithm around.

If you just want to modify the kernel you do not need any development environment at all. GPU kernels are compiled using the just in time compiler from the driver. Just make sure to remove the cached ...

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...

    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.

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

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

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...
