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

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.

1. A computer or jailbroken iDevice with Procursus
   • You can run permasigner on Mac OS X 10.5.0 or later, a Linux machine, a jailbroken iDevice, a Windows PC, or even just a web browser.
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.
     • On 15.0-15.1.1, you can use TrollStore to permasign apps jailed.

• Run Online
