README
End-to-end FairPlay decrypter for App Store apps.
Give it a bundle ID, get a decrypted .ipa. And yes - it happily decrypts iOS 26 apps.
Requirements
On your computer
- Jailbroken iPhone reachable over the network
On the jailbroken iPhone
All installable through Sileo:
| Package | Purpose |
|---|---|
| OpenSSH | SSH server - ipadecrypt drives the device over SSH |
| AppSync Unified | Bypasses installd's signature check (add repo https://lukezgd.github.io/repo) |
| appinst | Installs modified IPAs on the device (add repo https://lukezgd.github.io/repo) |
Tested on iOS 16.7.11 with palera1n rootless and Dopamine on iPhone 8 Plus. iOS 14 through 17 on A10–A14 devices are expected to work.
Install
Download a prebuilt binary from the releases page.
Using go install:
go install github.com/londek/ipadecrypt/cmd/ipadecrypt@latest
From source (refer to BUILDING.md for detailed instructions):
git clone https://github.com/londek/ipadecrypt
cd ipadecrypt
go build ./cmd/ipadecrypt
Usage
First-time setup
ipadecrypt bootstrap
A four-step interactive wizard:
- App Store sign-in - Logs into App Store. Credentials stay local in
~/.ipadecrypt/config.json. - Device connect - SSH host / user / password; probes iOS version + arch.
- Prerequisites - verifies whether deps are installed.
- Helper install - uploads helper binary and verifies whether it runs.
Decrypt an app
ipadecrypt decrypt <bundle-id|app-store-id|app-store-url|path-to-local-ipa>
List versions of an app
ipadecrypt versions <bundle-id|app-store-id|app-store-url>
Known issues
- New, unsupported SC_Info format is shipped with some apps, ipadecrypt will fail to decrypt them.
- Due to arm64e PPL guards on A12+, some apps such as Apple's are not expected to work.
License
MIT.
Prior art
- majd/ipatool - the Apple Configurator impersonation the App Store client is based on.
- 34306/TrollDecryptJB -
task_for_pid+mach_vm_readfrom a suspended spawn, entitlement set. - akemin-dayo/AppSync - installd signature-bypass tweak +
appinst. - JohnCoates/flexdecrypt - the pre-iOS-16 approach that stopped working and prompted the pivot.
