Government institutions have already been instructed to start using quantum computer safe encryption algorithms. Internationally, governments have been storing tons of encrypted data that they can’t currently decrypt because they expect to be able to decrypt it soon using quantum computers.

There are already quantum computer safe encryption algorithms that have been released to the public. I don’t know exactly how they work, but one of them was about reverse engineering a path through multi-dimensional space.

Expect SHA256 to disappear soon and be replaced.
