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.

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.
