While doing a iOS Security Testing, I wondered how do we convert .app into .ipa. So basically here are the structure of .ipa files. 1. First, SSH in your iPhone (Jailbroken). 2. Download the .app folder via scp 3. Copy the .app folder into a folder called Payload. 4. Compress it with .zip extension using any compression software. 5. Change the extension from file.zip to file.ipa. That’s it. Now you can use these .ipa files to install the app into your iPhone.
