They copy every packet, that's how they broke TOR when they took down Silk Road. Theoretically you can encrypt stuff that they can't decode, but they still know where it came from and where it went to.
If it's even theoretically possible to brute force decode some encryption, then the NSA can use quantum computers to instantly break it. It's like time travel for computer code.

Fortunately, the crypto market created massive incentive to build factories that produce chips designed solely for brute-forcing encryption.
