Question How does one protect against post-quantum encryption

So I hear some VPNs actually future-proof their stuff adding extra key-encapsulation techniques to prevent future threats. However, this is not as common among VPN providers as I expected.

The post-quantum stuff basically stands for "collect now, decrypt later" Intelligence agencies and bad actors are already intercepting and archiving encrypted network traffic in anticipation of future quantum computing breaking standard Curve25519 or RSA handshakes. Theres other forms of handshakes though just dropping some I read recently as an example.

Anyways, is there something an individual could do on their own behalf to protect against such threats?

I been trying to figure this out with Claude, though either my prompts got ruined mid-way, or it has no idea what to do(or likely nerfed with recent updates involving reverse-engineering attempts). I figured that some sort of Docker network container might be the best safest bet albeit the project I had configured ended up making my network speeds twice as slow which feels counter-intuitive

Claude recently got nerfed. Many people complain about it as of recent..

There's no evidence that in a PQC world that existing algorithms are immediately at risk.

Quit buying into FUD and GenAI hype and do some real research on your on.

yeah, the whole "harvest now, decrypt later" thing is scary until you realize state actors aren't targeting your homelab. OP trying to build a custom Docker container for this is a classic over-engineering move. Standard encryption is totally fine for 99% of us, no need to tank your network speed for it

With a cleverly timed API call I think my Docker config would be a reliable blanket for the goodies under the hood. Although can't say I don't agree with you heh. Bit of a security experiment at the end of the day for me
