I think this is probably the best case to point out the reason for avoiding backdoors in the system. The author put it more eloquently...<p><pre><code>  The problem with cryptographic backdoors is not that they&#x27;re the only way that
  an attacker can break intro our cryptographic systems. It&#x27;s merely that _they&#x27;re
  one of the best_. They take care of the hard work, the laying of plumbing and
  electrical wiring, so attackers can simply walk in and change the drapes.</code></pre>
