README.md

I've added offsets for all devices and versions. This is experimental and I will be replacing some of them with confirmed ones from previous commits

v0rtexNonce

Read or set generator(com.apple.System.boot-nonce variable) using siguza's v0rtex exploit.

The source code has a bunch of offsets. If your device's offsets can't be found in the source code, you maybe able to find them elsewhere. Search/ask /r/jailbreak. If the offsets you found are confirmed to be working, please add them to this project as a pull request.

Loading Offsets

Offsets are automatically loaded based on information from offsets.m by device and build id. Watch xcode's console and it'll show what device the app detects and a test offset(OFFSET_ROP_ADD_X0_X0_0x10) to verify if it loads the right offsets.

Adding offsets

If you wish to add offsets to this project, please read the note I left in offsets.m. Follow the format.

Problems

Keep in mind that this is still experimental. The exploit might take a number of tries to succeed. Just keep trying. At one point, I had to try more than 20 time in a row.

Make sure to have Xcode 9 or higher to compile!
