Firmware Keys
VFDecrypt Keys are the keys which can decrypt the files that come with the (beta) firmware. Apple uses a public/private key encryption to ensure the safety of their files. Over time Apple has changed the way to encrypt firmware files, thus the way to decrypt files as well as the way to get the keys has also.
IMG2 was the file format used prior to iPhone OS 2.0. For iPhone OS 1.1.x, IMG2 files were encrypted with Key 0x837.
IMG3 encrypted files contain encrypted versions of the VFDecrypt Keys as part of the KBAG (key bag). These can be decrypted with the GID-key. For jailbroken iDevices the VFDecrypt keys can be retrieved with the devices hardware AES engine. The VFDecrypt key for the root filesystem (the biggest file) image of an iDevice requires either a decrypted Restore Ramdisk or Update Ramdisk. Once you have a decrypted Restore or Update Ramdisk, GenPass can be used to gather the keys for the root filesystem.
For the root filesystem there is one key per device model, with no IV. You can mount this once it has been decrypted using your program of choice. (For example, 7-zip on Windows (after extracting the DMG on Windows, extract the biggest file with 7-Zip)

Certain files share the same key and IV per application processor (per build):
- Update Ramdisk
- Restore Ramdisk
- AppleLogo
- BatteryCharging0
- BatteryCharging1
- BatteryFull
- BatteryLow0
- BatteryLow1
- GlyphCharging
- GlyphPlugin
- Kernelcache
- NeedService
- RecoveryMode
- WTF?
The table on the right lists the application processors and their corrosponding devices. This list is also accessable from the main page.
You can use img3decrypt[1] or xpwntool[2] to decrypt these files as described in Ramdisk Decryption. Once done, mount or extract using the tool of your choice.
When posting a key page, please use the key template (IN THE CORRECT ORDER) and do NOT substitute it.
The firmware version number for the Apple TV builds are the ones that the Apple TV reports.
All dates are relative to UTC.
iOS 6.0b1 and higher no longer work with VFDecrypt. You need to use dmg[3] to decrypt these. The decryption process is longer as it writes the progress to the terminal unlike VFDecrypt.
