iphone backup...
#1
OK, so in 24 hours ive plunged down the rabbit hole. My girlfriend backed up her old phone with a password, traded it in, it got wiped, we got a new phone and now cant back up because we dont have the password. pics and texts from late relatives, etc. So, I watched a dozen hashcat instructional videos and tried to get everything to work without trying to learn a whole new language. I have a pc and a mac, i tried to do it on the pc using a perl script i found but couldnt get perl to work so tried on the mac and couldnt get hashcat to work no matter what i tried. I stayed up all night and spent all morning, I know you guys are gonna fry me for "not knowing how to use my os" but I'm posting in desperation. Now, I probably wouldve had less trouble if it was an older version because the best video on the subject takes you through ios 10 and lower, and only touches on 10+. and seeing as i have 11.2 i need the dpic and dpsl values too. However, when i even attempted i realized that my free choice in hex editors dont show values or bit length. So, to anyone with a heart, I'll attach my manifest.plist from google drive. I thank you in advance, go easy on me i tried to teach myself hex in a single night. lol 

manifest.plist

Install Perl on your windows machine
https://learn.perl.org/installing/windows.html

Use iTunes_backup2hashcat on the manifest.plist and it will give you an output similar to the example show here (mode 14800)
https://hashcat.net/wiki/doku.php?id=example_hashes

Take the output from the previous step and use with hashcat

One massive point though, you won't be getting decent speeds without some decent hardware because its a slow algorithm. If you have no idea what the password might be and you are just purely guessing, it will take a very long time.
