      We should definitely panic because never before have we had to consider the possibility that today's state-of-the-art encryption scheme may be obsolete in... *reads article* ... Twenty-five years?https://twitter.com/techreview/status/1134306260692586497 …

      People have secrets today that they might want to stay secret in 25 years. We're actually integrating Post-Quantum security into Amazon s2n right now for that reason :)

      I think that people do have things they want to keep secret for more than 25 years. But has there ever been a crypto algorithm that was still secure 25 years after its peak use?

      Replying to @tacertain

      RSA and DH have remained secure and common that whole time. Group sizes have increased, to keep pace with Moore's law, but even 25 years ago some people were using 4k and 8k keys. Problem is Quantum is the end of the road for that!

      Replying to @colmmacc @tacertain

      ... I think we can say with certainty that quantum breaking RSA won't happen due to some steady growth from 70 to 20 mill qubits. It will require a radically new paradigm, just as one would have thought in 2002. More radical than what has happened in the intervening 17 years.

      Nice try, NSA plant account 🤣 You're right, but it's still true that "We now have a way to break RSA that doesn't break the laws of physics". Scaling is a very hard eng challenge, but some people don't want to bet that it's like Nuclear Fusion, rather than like semiconductors.

          I think NSA could do better! I don't understand what you mean... when you say "now have a way... doesn't break physics" I assume you mean in a theoretical sense. But those 2002 ideas didn't break the laws of physics either, they were just not practically unrealizable...like today

          People look to cryptography for mathematical certainty. Practical realizability can change over night with invention and the most well funded adversaries keep their progress secret. That makes people want to hedge.
