When you update your iDevice, iTunes downloads a firmware file. If you open up the firmware, you will find many small files along with one big one. That big one is the (encrypted) filesystem (i.e. the one that is installed on the device). If you use iDecryptIt on the file, iDecryptIt will decrypt it. The decrypted file can then be extracted with (the included) 7-Zip or mounted as a virtual hard drive with certain tools.

** Please do not contact me asking for keys. The keys provided by iDecryptIt are NOT my own work, but the contributors to The iPhone Wiki.

** Support for the other files contained in the firmware is coming.

Is your CI/CD pipeline a hodge-podge of randomly connected tools?

Gartner’s Recommendations for DevOps Pipeline Success Icon
You’ve likely added a tool to fix one problem and then a different tool to fix another problem. Pretty soon you have multiple instances of the same tool, different tools with overlapping functionality, no ability to collaborate across teams—all resulting in unknown bottlenecks and complicated or no reporting. As a DevOps leader, it’s up to you to balance the autonomy and flexibility of a DevOps approach. But how?
