Quantum resistant encryption is already available
- JBits 4y agoWould you be able to give any examples of quantum resistant encryption algorithms? I'm not familiar with the field and my most recent knowledge is a post on hn saying that some post quantum candidates had been broken by old laptops.

- GTP 4y agoThe whole symmetric key cryptography (e.g. AES) ia already quantum resistant. The problem only holds for public key encryption, but as the other commenter pointed out, there are already promising algorithms.
- JBits 4y agoThat's nice, I didn't realise AES was quantum resistant. However, an algorithm being promising doesn't mean it works. Do you know how well the development of these other techniques is progressing?
- GTP 4y agoI'm not an expert in the field, but there is already a NIST competition going on to stansardize post-quantum public key ciphers. So I would say that we're at a good point in post-quantum cryptography development.
- kragen 4y agoIt's potentially quantum-resistant depending on how it's used. Grover's algorithm still reduces your effective key length by half in many situations.
- jl2718 4y agoNo. Encryption that is "not provably quantum-insecure" is available. I doubt this will ever extend to "provably quantum-resistant".
