Itunes Backup recovery strategy

[ensign.fodder]

I am trying to avoid paying to unlock my wife's iPad backup. I have a new device for her and want to migrate to it with a few lost items as possible.  
On her MAC she did not tell it to keep the encryption password in Keychain and on my Windows PC the password is not recoverable.

I found my way here and using the pl script I was able to get the $itunes_backup$*9*wkpy*iter*salt** - (partial shown: $itunes_backup$*9*a8c7351ffc551...) and I have passed that to hashcat as itunes9.txt 

Code:

hashcat64 -m 14700 --weak-hash-threshold 0 itunes9.txt

Hashcat seems to be running:

Code:

Session..........: hashcat Status...........: Running Hash.Type........: iTunes Backup < 10.0 Hash.Target......: $itunes_backup$*9*a8c7351ffc551... Time.Started.....: Sun Feb 26 16:02:51 2017 (12 mins, 16 secs) Time.Estimated...: Sun Feb 26 16:15:07 2017 (0 secs) Input.Base.......: Pipe Speed.Dev.#1.....:        0 H/s (0.00ms) Recovered........: 0/1 (0.00%) Digests, 0/1 (0.00%) Salts Progress.........: 0 Rejected.........: 0 Restore.Point....: 0 Candidates.#1....: [Copying] HWMon.Dev.#1.....: Temp: 43c Fan: 40%

But I d not know enough to know if this output is normal/std.  I tried a password file of ones we would have used (Windows, Mac, Pin, iTunes, etc) but that ran about five seconds and ended so I presume none of those we valid.  Having already tried them I doubted they would.

Any help/thoughts?

Thanks
