## What it is
bagbak is a Node.js CLI tool that uses Frida to decrypt iOS App Store binaries on a jailbroken device, dumping decrypted IPAs including app extensions. It is now deprecated in favor of mremap_encrypted-based approaches that do not require running the target app.

## Use cases
- decrypt an iOS app binary from a jailbroken device
- dump a decrypted ipa for reverse engineering
- decrypt app extension binaries on iOS
- list installed apps on a jailbroken iPhone
- remove device restriction keys from an app's Info.plist
- analyze App Store app binaries in a disassembler

## When to avoid
- you need a decryptor that does not require running the target app (use mremap_encrypted-based tools like UnFairPlay or unfaird)
- your target app has RASP protections that block runtime dumping
- you have no jailbroken iOS device

## Facets
