Revision as of 22:54, 8 June 2012

VFDecrypt Keys are the keys which can decrypt the files that come with the 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 VFDecrypt Keys has also.

IMG2 was the file format used prior to iOS 2.0. For iOS 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 image of an iDevice (~500 MB to 800MB in the case of iOS 5) 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)

Notes

The Update Ramdisk and Restore Ramdisks share the same IV and key per type of Application Processor. The current models are:

Application Processor iDevice
S5L8900 iPhone, iPhone 3G, iPod touch
S5L8720 iPhone, iPod touch 2G
S5L8920 iPhone 3GS
S5L8922 iPod touch 3G
S5L8930 (A4) iPad, iPhone 4, iPod touch 4G, Apple TV 2G
S5L8940 (A5) iPad 2, iPhone 4S
S5L8942 (revised A5) iPad 2 Wi-Fi R2, Apple TV 3G
S5L8945 (A5X) iPad 3

You can use img3decrypt[1] or xpwntool[2] to decrypt these 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.

For the VFDecrypt Keys of each firmware please check the builds listed at the appropiate firmware version page.
