Firmware Keys

Firmware Keys are keys which decrypt the root filesystem of certain (beta) firmwares. Apple uses a 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.

History

With the release of the iPhone came the IMG2 file format. They were used on all known iPhone OS 1.x firmwares. For the 1.1.x series, they were encrypted with the 0x837 key. The discovery of the 0x837 key led to the ability to decrypt any 1.x firmware.

Following IMG2 came the IMG3 file format. They were introduced with iPhone OS 2.0b4, and have been in use ever since. In order to maintain their integrity, they contain multiple layers of encryption, all based around a public/private key encryption method. Apple took encryption seriously with IMG3 by utilizing AES (based on the Rinjndael key schedule). In order to complicate things, they contain the VFDecrypt key, albeit encrypted, as part of the KBAG structure in the ramdisks.

The ramdisk keys can only be retrieved with the processor specific GID Key. The GID key is currently unretrievable and can only be utilized through the built-in AES engine. To complicate things even more, the engine is only accessible through a special bootrom exploit (jailbreaks typically expose it with /dev/aes_0). This makes usage of the key nearly impossible.

However, once you have access to the AES engine, the entire system falls apart. You are able to upload an encrypted ramdisk and grab the decryption keys for it. Once you manage to decrypt the ramdisk, you can run it through GenPass to decrypt the Firmware key.

Beginning with iOS 6.0b1, Apple tweaked their disk images so they no longer work with VFDecrypt. VFDecrypt will report that the filesystem is decrypted, but you will be unable to mount it. The current workaround is to use dmg from Xpwn to decrypt them. What has changed to break VFDecrypt is currently unknown. Decryption will take slightly longer due to dmg writing its progress to the terminal, but the difference is negligible.

To find the keys, you can either use the the methods on AES Keys or the easier option, for OS X, keylimepie.

Certain files share the same key and IV per application processor (per build):

The table on the right lists the application processors and their corresponding devices. This list is also accessable from the main page.

You can use img3decrypt or xpwntool to decrypt these files as described in Decrypting Firmwares. 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.

You cannot get A5+ keys until a bootrom exploit is found. If the ramdisk is not encrypted, you may then get the RootFS key ONLY.
