we should be pessimistic about our cryptography

I agree completely. Which is why i'm going to continue using our current incredibly well tested and analyzed 2 main asym crypto families, instead of a bunch of other random shit no one uses that have a bunch of down sides.

so can the nsa decrypt shit like truecrypt reliably yet?

I meant pessimism on the power of Quantum Computers.
Always assume your enemy has all the tech in the world.

No, we are talking PGP here.

One-time pads will still be safe, so long as you use them properly. Best of all, it's very simple and doesn't require powerful (i.e. botnet) hardware. Any 8-bit computer will manage well enough.

Ah right so we should not be pessimistic about crypto at all and start using all these untested new crypto systems. Great idea mr retard.

You have to go manually meet anyone you want to talk to. It can never work for websites or anything else only people you physically know.

No, we should be pessimistic about BOTH Quantum Computer's power AND untested cryptosystem being part of (((NSA's))) plan.
