itunes backup >10 - am i doing it wrong?
#1
ALl,

Am I doing this wrong?  I have one hash from manifest.plist for iTunes 10.2  When I run hashcat using just a dictionary (like example.dict), it will make about 15 guesses per second on my blazing fast NVidia GeForce GTX 960M.  If I use the rockyou-30000.rule with a meager 6 word dictionary (I think the password was built using one of these as a base), I'm making one guess every 45 seconds with an estimated time to complete shortly before heat death of the universe.

Here is my command line:

hashcat64.exe -m 14800 hash.txt wordlist.dic --rules ./rules/rockyou-30000.rule

And the status:

Session..........: hashcat

No it's fine, iTunes backup >= 10.0 is doing 10,000,000 iterations of PBKDF2, so it's actually that slow. I meassured a single computation on CPU to run > 40 seconds.
