Restore data from encrypted iOS backup without respective device

My iPhone stopped working but I have encrypted backups on my machine. I won't get a new iPhone but I obviously want to extract all my data. Is there any tool how I can extract the data without buying a new iPhone?

I know about many 3rd party tools, but they all have a cost behind it, and I'm wondering if you know a way to do this.

Solution 1:

You can decrypt an iTunes Encrypted Backup (when the password is known) using backup_tool.py from iphone-dataprotection on Google Code.

Navigate to an suitable destination in Terminal, then run the following:

hg clone https://code.google.com/p/iphone-dataprotection/
python iphone-dataprotection/python_scripts/backup_tool.py ~/Library/Application\ Support/MobileSync/Backup/backupname decrypted

^{Replace backupname with the encrypted backup folder name.}

The tool will prompt you for the encryption password, then output the decrypted backup to the folder ‘decrypted’.
