No more rocket science, I'm moving to Post-Quantum encryption any day now...

Post Quantum Cryptography: Why We Need Resistant Encryption NOW.

Quantum-resistant or post-quantum cryptography is our best bet against attacks from upcoming quantum computers to increase security and privacy.

I would use a pre-quantum (e.g. EC) and post-quantum (e.g. KYBER) at the same time. The math behind KYBER Is rather new and other algorithms in the NIST competition have been cracked (rather late in the process!) in a couple of hours on classical hardware.

@jornfranke That's exactly what we do; it's a hybrid protocol using both new and 'old', proven algorithms.

It kind of boggles my mind how quantum safe encryption is even a thing that can be achieved, especially without the use of quantum computing itself.

Does anyone know a good basic primer for someone who understands standard encryption (just) but isn't any kind of computer scientist / theoretical mathematician etc?

Not... really.

The blog post says what projects are being used to encrypt, but the only mention of how is one sentence about that they use problems considered "too difficult" for a quantum computer to figure out. There's no mention, not even a sentence, of what kind of problem or why it would be difficult, which is exactly what I'm wondering.
