&gt; As the UK&#x27;s politicians continue to fail to understand what &quot;strong cryptography&quot; or &quot;banning&quot; even mean, I thought I would have a look at how simple strong cryptography can be.<p>Not that I think it&#x27;s a good idea or believe they have a good understanding of cryptography but: if they are being rational about it, I&#x27;m guessing they think making strong cryptography less convenient will lead to less encrypted communications between parties they&#x27;re interesting in snooping on. In this case, WhatsApp would be a considerably more convenient to use than using DOSBox.
