In the DNC debate on Saturday night, Hillary Clinton expressed that she wanted to work with Silicon Valley on a &quot;manhattan-like project&quot; to give government a backdoor into encrypted communication.<p>We&#x27;re the silicon valley people that are being talked about, but I have absolutely no idea what this would look like, and I don&#x27;t actually think that it&#x27;s even possible.<p>What would that look like?  I know of times in the past where there have been possible flaws in various pieces of crypto (there was a bad random-number generator being used for a specific implementation of OpenSSL at one point, for instance), but what would a government backdoor look like?<p>Everybody I&#x27;m reading is saying that just means writing bad crypto, and that there is no way of giving the government, and only the government, a key to the crypto.<p>If you were asked to create what Hillary Clinton is asking for here, what would you create?  What would it look like?
What would a “manhattan-like project” cryptographic backdoor look like?
