Decrypt iTunes Backup File

Question

I have a backup of my device stored in iTunes. iTunes created a folder for my device. Now I have *.mddata and *.mdinfo files. The problem is that I accidentally told it to encrypt these files so now they are not viewable. I'm wondering what the best way to decrypt these files is, without losing this encrypted copy.

Answer 1

Why do you need to decrypt the backup? Do you still have the iPod? Do you have the password? If you do a restore from backup it will ask you for the password and it will restore the iPod with the information from the encrypted backup:
