TL, Dr. ;) To summarize: you are cracking an iTunes backup (probably the newer -m 14800, >= 10.0 version) on a single GTX 970, and you're looking for better options. On the spectrum of dictionar...

You might first try a dictionary like rockyou.txt, which has a number of common passwords, in case it was something simple. After that, there are some decent howtos out there for growing your hashc...

starkk, length is usually unknown - but you can usually make some good guesses (and start small). Also, brute force should be your last option. You should be trying wordlists, combinator, hybrid (w...

Ah, OK. The best wordlist I know of, bang for the buck, is the hashes.org founds (the "found in plain" here: https://hashes.org/left.php).

By default, hashcat only uses GPUs when available. You can modify that with these flags. Code: -- $ hashcat --help | grep opencl-device -d, --opencl-devices           | Str  | OpenCL device...
