Are the updates encrypted in any way (VFDecrypt?) --Balloonhead66 18:31, 30 August 2011 (MDT)
- No. Just regular Zips. --M2m 22:36, 30 August 2011 (MDT)
- Only NOR payloads and RAM disks are encrypted, rest of the "asset" is unencrypted --pjakuszew 04:19, 31 August 2011 (MDT)
- But if you need to update iTunes to 'decrypt' the newest firmware (as iTunes contains the 'password' to do so), then that means that the encrypted stuff has a 'password' that is somewhere on the file system. Maybe if we could access it, we could get them. (maybe disassembling iTunes could get us them also :D) --Balloonhead66 11:12, 31 August 2011 (MDT)
- iTunes doesn't contain any "passwords" Balloonhead66. Everything is done on the device and usually uses the device's built in hardware AES crypt keys. -- iH8sn0w 13:32, 31 August 2011 (EST)
- Dang, but then why do we need to update iTunes to update our device? --Balloonhead66 11:35, 31 August 2011 (MDT)
- Its purpose is to send out firmware files to the device, and only that. --pjakuszew 11:36, 31 August 2011 (MDT)
