NSA Bullrun program
	To be fair, it's a little hard to know exactly what all it entailed
	Snowden release give a fair bit of information about it
	
A bit of history on this:
	First:  What does it take to break a cipher?
		And how safe are they, really?
		Key length, obviously
		Perhaps less so:  Differential cryptanalysis
	The skipjack cipher story

An example:  Wifi snooping
	The good old days:  Easy!
		If you're in 252, I got my demo working finally
	WEP, then WPA, then WPA2 and WPA3 made it much harder
	Even if you can watch, HTTPS is ubiquitous
	Can still see where traffic is going!
		Proxy servers?  Tor?  Secure DNS and clouds?

In order to prevent snooping, what's needed?
	We've got essentially all the pieces from the bitcoin bit
		A way to send a key (public key)
		A signed key for the party we're connecting to (certificates)
		A symmetric cipher to communicate efficiently with

How could the NSA undo any of that?
	"could"
	Here's an example:  Use heartbleed to recover server's private key
		Then use the private key to impersonate the server
		Re-encode the traffic and send it on (man in the middle)
		Attacker gets an unencrypted copy of the traffic
		Attacker can also change content
		Have to be creative to get there in a networking sense
	Another "could":
		Contribute changes to key generation algorithms that are less random
			The should appear random
			But perhaps the actual generated key space is smaller than expected!
	Yet another:
		Pressure a commercial company into granting access
	Remember, implementation is the source of most security bugs!
