Cracking Your Collection

Have you ever downloaded/installed legacy applications only to find out that they are locked to an iTunes account?

This due to sharing encrypted ipa files, or backups from iTunes/IPA installer. In order to share your legacy apps so that others may install them on their jailbroken iDevice, you need to properly "crack" them, or more precisely decrypt them.

There are two main tools for doing this right from your device: Rasticrac and Clutch. Current releases for both have abandoned legacy support, but fortunately, Clutch is open-sourced and document releases.

Note about Rasticrac: According to the internet this tool is supposed to be the best for decryption, but since it is closed source the only way to install it is through the appcake repo which installs many iOS 8 dependencies and does not work from my testing.
Moderator edit (3/16/20): Rasticrac is available for download on the Momentum Dev Repo (http://repo.mtmdev.org)

Requirements: MobileTerminal, Clutch, iFile

If you are on iOS 6 or below head over to the github release page. The last stable release is 1.4.6 which still supports legacy versions (For iOS 5 and below I believe 1.4.3 works the best, but I do not have a device to test).


If you are iOS you need safari download manager or a downloader application. Just click on the Clutch-1.4.6 link. It should automatically download, and should not have an extension.


Navigate to where you downloaded the file:

To edit properties click on the blue arrow next to the file name. Feel free to change its name to something shorter as you will be typing it in MobileTerminal a lot. Also make sure all properties are set to executable:

Move this file to "/usr/bin/"
You should see a bunch of other extensionless files.

Now we can begin decrypting!

For this tutorial I will be cracking MangaReader, a free app removed by Apple a few years ago.

Open the MobileTerminal application and type:
Code:
su root


This gives you root privileges so you need to input your password (you wont see it being typed). The default password is
Code:
alpine

It is highly recommended that you change your root password. To do this type
Code:
passwd
(It should be memorable and not complicated just not the default)

Next type
Code:
clutch -C
or whatever you named the file followed by a capital "C" to configure clutch.

To keep the default configuration value listed just hit return. For the direction to place IPA's just hit enter, custom directories are very buggy. I suggest to use a number based system. For the email you can enter anything you want.

Important: Use native zipping, otherwise you get an error.

Once you are done, just type
Code:
clutch
(or whatever you named your file. You should see a numbered list off your non-cracked applications:

Slide on the right side of the screen to scroll up or down.

To crack and app type
Code:
clutch
(or file name) followed by the number of the application. So for me
Code:
clutch 16

Once it is done you should see the cracked ipa file in the designated directory.

That's all! :) I hope this tutorial was clear enough. Please share you apps and enjoy cracked apps from others!

Note: The apps you're cracking must be tied to your appleid or else you will get a error.

Hi,
Does anyone know why is this happening?
I followed the steps correctly on my iPod 4 (iOS 5).
It was working fine before, but I factory reset my device and redid everything and this kept happening.
Please Help.

I can't install Rasticrac or Clutch, because it keeps saying I need Darwin CC Tools, which requires ld64, which requires iOS 5. But the device I'm trying to crack apps on is an iPod touch 2nd gen, and the max iOS version it supports is iOS 4.2.1. Can someone help me get past this?

How does one get the .ipa files to crack in the first place? Could someone explain the process to me? Thanks!

You first have to have an unmodified application installed, then you use one of these scripts to remove your Apple ID from it, cracking the DRM
