&gt; Encryption is either secure or it isn&#x27;t. You can&#x27;t have a middle ground.<p>Technically, there is some limited middle ground due to key escrow (clipper chip[1]) or cryptographic backdoors (DUAL_EC_DRBG[2]).<p>Both are interesting because the encryption algorithms stay mathematically strong.<p>Obviously, the golden keys would have to be well-protected. But that&#x27;s mostly a solved problem; see CAs.<p>(Of course there&#x27;s the problem of which governments get the keys. And it&#x27;s good that Clipper and DUAL_EC_DRBG died.)<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Clipper_chip" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Clipper_chip</a>
