# websec: post-quantum cryptography, all of today's secrets will be lost (!)

AA << analyze the options available for a post-quantum cryptography future >>

<< The expectation is that quantum computers will be built some time after 2025 >>

<< An attacker can record our secure communications today, and break it with a quantum computer years later. All of today's secrets will be lost >> Tanja Lange
