Decrypting iOS Applications (Automatically)

My previous post was about how to decrypt the iOS application manually. It is good to know how does it work but it can be tiring if you want to decrypt many applications. All the mentioned steps are gathered together in one tool - Clutch by KJCracks.

Clutch

The application and source code are available on the github https://github.com/KJCracks/Clutch/releases. Clutch automatically decrypts the application and creates the .ipa files.



Using the Clutch

You need only to download the application from the github (the compiled version is available). Running Clutch without parameters shows all available applications that can be decrypted. Running Clutch with the name from the list decrypt the application, running with "-a" decrypts all listed application.


After the application is decrypted it can be installed as the ipa package and analyze.
