&gt; Here&#x27;s hoping that the iPhone 7 has a secure enclave that either 1.) deletes keys on firmware flash, or 2.) doesn&#x27;t allow it to be upgraded ever.<p>If you hope for that, consider the legal base on which FBI made the current request: All Writs Act, which is, in full:<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;All_Writs_Act" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;All_Writs_Act</a><p>&quot;(a) The Supreme Court and all courts established by Act of Congress may issue all writs necessary or appropriate in aid of their respective jurisdictions and agreeable to the usages and principles of law.<p>(b) An alternative writ or rule nisi may be issued by a justice or judge of a court which has jurisdiction.&quot;<p>Note it&#x27;s not any kind of law that regulates any form of encryption or communication security, a lot of laws with such topics were fought through the years! It&#x27;s just &quot;we can demand anything we want.&quot;<p>Then consider how long such Secure Enclave will last if this precedent on such use of this Act is now to be made.
