Give me a half hour and a $500 budget (cash) to go shopping at Home Depot, Canadian Tire or some other DIY shop and I can do some fairly bad things. Tools will <i>always</i> be dual use, the same encryption that powers your e-commerce can be used to fairly reliably communicate between two parties if the best-before-date of the communications is something on the order of a few weeks to months.<p>So you basically get to choose: we stop <i>all</i> tools from being freely available and we open up all our communications to criminals and governments alike <i>or</i> we will have to take the good with the bad.<p>The people who wrote crypto software (and the people who built TOR and who operate anonymous proxy servers, VPN services and so on, built bitcoin, the internet, your browser and your mail client) all realize their work is &#x27;dual use&#x27; and there is absolutely nothing that you can do about it so just let it go and accept it.<p>That same hammer that can pound in a nail in the hands of a carpenter (skilled or not) can be used to bludgeon someone to death. Should we ban hammers? How should the person who invented the hammer feel?<p>A tool I invented is used by some pretty bad people. I don&#x27;t like it much. But I recognize that that same tool is also used for good, and that those good uses are probably the majority of them. It used to bother me, but I got over it, now I do think longer and harder about if there is any possible bad use of the stuff I make that I can make harder by designing the stuff I build in a different way. It doesn&#x27;t always work out and people are pretty clever about finding alternate uses.
