&gt; he only thing any of us are missing is the 4096-bit RSA encryption key used to sign the firmware.<p>Ah, so Apple&#x27;s encryption does actually work.<p>That&#x27;s the essence of the good encryption: everything is known, except the key. You are not supposed to have it. FBI, hopefully, isn&#x27;t supposed to have it too. That&#x27;s why we have laws. Checks and balances and stuff. Laws made for specific cases, not &quot;we can do anything.&quot;
