Q: Encrypted password

Sorry but no. See the information below from About encrypted backups in iTunes - Apple Support

What if I can’t remember the password for my encrypted backup?

You can't use an encrypted backup if you don't have the password.

When you try to use a backup, you might see a message saying "The password you entered to unlock your backup was incorrect." This message means that the iTunes encryption option was turned on in the past by:

• Yourself
• Someone who set up your device or transferred your data to a new device
• An installed profile (for business or education devices). If you're using an installed profile, contact your system administrator.

If you don't have your password:

• If someone else set up your device, check with them for the password.
• Try using an iCloud backup instead. If you don't have an iCloud backup, you can make one.
• If it's still relevant, try using an older iTunes backup.

How can I turn off iTunes backup encryption?

To turn off iTunes backup encryption, enter the password and uncheck the Encrypted backup box in iTunes. Your encryption password is always required to turn off backup encryption.

You can't use an encrypted backup if you don't have the password. If you forgot your password, the only way to turn off backup encryption on your device is to erase your device and set up as new. Erasing removes all data from your device. If you don't want to erase your device, restore from an iCloud backup instead.
