Dont worry, Eric Holder (and slimy filth like him) will go crying to congress, telling them all about how but-hurt strong elliptical curve crypto makes them because it stops them being able to indiscriminately decode all that data going over the inter-tubes. (Gotta use language the congress critters understand you know.) "Normal citizens should have nothing to hide, and thus shouldn't have any reason to use such dangerous, 'munitions grade' cryptography!" they will whine. "Such strong crypto should only be used by government agencies, and we should have a strong hand in approving publicly used cryptographic libraries and functions!" they will sob at the congressional hearing. "Imagine how terrible it would be if Osama Bin-Laden had been able to fully encrypt all of his traffic end-to-end, and was able to use redundant, distributed proxies to hide his location!", and other such "oooh! Spooky! Baaaaad things will happen if we cant keep our tentacles in everyone's stuff!" type arguments.
Just look at how butt-hurt they are already about google and apple implementing strong full-device crypto on android and ios devices. You can bet they would be moaning about how sandy their manginas feel if full end-to-end strong encryption with strong, true-random keys were to be used at every point on the internet.
"Why, we would have to actually use real agents that arent just jackbooted thugs in uniform, and use actual detective and police work to have government intelligence instead of just dumping hundreds of terabytes of collected feeds into a giant sorting and collating algorithm! Think about how much that would reduce our response times should a major terrorist action be started! Why, we might not even know about it until it happened! WHooooo! Scary! Better give us what we want so you can feel safe!"
And, at that point, you would end up with government mandated weaknesses in your VPN security, in your proxies, and even in your very network switches themselves. Perhaps even wholly secondary channels tracking routing to collect data exchange meta-data to help identify "suspicious" use patterns, etc.
Eric Holder and his slimewad cock-goblin friends would be all over that shit like stink on shit, and the corrupt and horribly incompetent congress critters would be wiggling their asses every which way to give it to them. Bet on it.
