Permanently sign IPAs on jailbroken iDevices 14.0-14.8.1 (persists on stock)


How does it work?

In iOS 14.0-14.8.1, there is a bug where CoreTrust will allow any root certificate. Although the bug exists on iOS 15.0-15.4.1, it can not be abused (yet) since you need to be jailbroken at first to place the app in the /Applications folder. This bug does not exist on anything older than iOS 14.

This script makes a deb file for you based on an IPA. Tested only with Taurine, but should work with many others.

Based on the resign_taurine branch of CoreTrustDemo, please note that certificates are not copyrightable.

Prerequsites

  1. A computer or jailbroken iDevice with Procursus
    • Mac OS X 10.5.0 (?) or later required.
    • (Basically) any Linux distro is supported.
    • A jailbroken iDevice using the Procursus bootstrap is supported.
  2. Jailbroken "target" iDevice on 14.0-14.8.1
    • The device needs to be jailbroken at first to place the app in the /Applications folder. After installing it'll continue working on stock.
