pyzule-rw / cyan

a rewrite of pyzule that doesn't (completely) suck !!

features

you can open an issue to request a feature :D !!

• generate and use shareable .cyan files to configure IPAs!
• inject deb, dylib, framework, bundle, and appex files/folders
• automatically fix dependencies on CydiaSubstrate (cyan uses ElleKit!), Cephei*, and Orion
• copy any unknown file/folder types to app root
• change app name, version, bundle id, and minimum os version
• remove UISupportedDevices
• remove watch app
• change the app icon
• fakesign the output ipa/app
• thin all binaries to arm64, it can LARGELY reduce app size sometimes!
• remove all app extensions (or just encrypted ones!)
