  • Quantum computers are nowhere near usable for breaking classical cryptography at the moment, though opinions on how soon it will come vary. As others have said, we have quantum resistant algorithms ready to go, so future encryption is fine.

    The greater concern is that a lot of traffic and data encrypted using classical algorithms has been logged or stored in various mediums. An old encrypted drive, or communications stored by nation state actors (the NSA and such). These will be broken, and a lot of past secrets might come out from hiding.
