Im attempting to restore the back up from my previous phone, on to my new phone, but have absolutely no idea what the password is. Ive exhausted every single password ive ever used. I had no idea about the whole encrypted thing but it was obviously ticked and i must have made a password. Any ideas how i can un-encrypt the back up from the previous phone, or how to possible retrieve that password?? I am running low on patience. I was trying to restore a backup with an encrypted password which I had completely forgotten.

I followed these steps and it worked!! The encrypted back up password was recovered!! Oh, and this is after Apple Support told me there is absolutely no way to recover the password and I would have to purchase more storage for my old iphone and use icloud to back up… thank you for this article! Later I recovered the password with iTunesKey.
What can I do? Please someone help me. I think I found it! Thank you so much!!! Although my iPhone password did not work, the one for my iPad did!

How to decrypt an encrypted iTunes backup
It has powerful ability to recover not only common but also encrypted data from iTunes or iCloud backup, or from iOS devices. Though you are allowed to choose kinds of backup extractor tools in current market, Joyoshare iPhone Data Recovery is the one you should not miss. Better yet, you are entitled to preview these results in real time and selectively choose needed items. All Rights Reserved. Now you know that every file in iOS is encrypted with its own random per-file encryption key, belongs to a protection class, and the per-file encryption keys are stored in the filesystem metadata, wrapped in the protection class key.
Decode the keybag stored in the BackupKeyBag entry of Manifest. A high-level overview of this structure is given in the whitepaper. The iPhone Wiki describes the binary format: a 4-byte string type field, a 4-byte big-endian length field, and then the value itself.

Using the backup password derive a byte key using the correct PBKDF2 salt and number of iterations. Unwrap each wrapped key according to RFC Decrypt the manifest database by pulling the 4-byte protection class and longer key from the ManifestKey in Manifest. You now have a SQLite database with all file metadata. For each file of interest, get the class-encrypted per-file encryption key and protection class code by looking in the Files. Strip the initial four-byte length tag from EncryptionKey before using.
Then, derive the final decryption key by unwrapping it with the class key that was unwrapped with the backup password.
Forgot iTunes Backup Encryption Password, How to Recover?
In runnable source code form, here is how to decrypt a single preferences file from an encrypted iPhone backup:. That code no longer works on backups from phones using the latest iOS, but there are some golang ports that have been kept up to date allowing access to the keychain.
Sorry, but it might even be more complicated, involving pbkdf2, or even a variation of it. Listen to the WWDC session , which mainly talks about the security measures in iOS 4, but also mentions briefly the separate encryption of backups and how they're related. You can be pretty sure that without knowing the password, there's no way you can decrypt it, even by brute force. Let's just assume you want to try to enable people who KNOW the password to get to the data of their backups. I fear there's no way around looking at the actual code in iTunes in order to figure out which algos are employed.
Back in the Newton days, I had to decrypt data from a program and was able to call its decryption function directly knowing the password, of course without the need to even undersand its algorithm. It's not that easy anymore, unfortunately. I'm sure there are skilled people around who could reverse engineer that iTunes code - you just have to get them interested. In theory, Apple's algos should be designed in a way that makes the data still safe i.
And in WWDC session they went pretty deep into details about what they do to accomplish this. Maybe you can actually get answers directly from Apple's security team if you tell them your good intentions.
After all, even they should know that security by obfuscation is not really efficient. Try their security mailing list. Even if they do not repond, maybe someone else silently on the list will respond with some help. Haven't tried it, but Elcomsoft released a product they claim is capable of decrypting backups, for forensics purposes.
Maybe not as cool as engineering a solution yourself, but it might be faster. Listen now. Learn more. How to decrypt an encrypted Apple iTunes iPhone backup? Ask Question. Asked 10 years, 1 month ago.
