Plz help with iTunes encryption

[zinzin112]

I need a lot of help with iTunes password recovery.  I have the manifest pst but cant do anything more.  My vindictive ex-wife changed my password, and now encrypted, so i cant back up any of my devices.
i have tried to install Hashcat, but errors come up.  I have managed to postpone court documentation until after Xmas, so i do have a little extra time now to gain access.
Currently trying Brute-force, but 16Billion passwords later, still going on 6 characters.
If someone can PM me for further details.
I really really need this help.
Tks!
Zin.

It's not clear what exactly your problem is.

dictionary-based attacks (-a 0) with rules (-r) are in general more clever compared to "brute-force" except if you know for sure that the password is 100% randomly generated
