Cloudflare releases an online tool to check if the BGP you are using (the ISP/AS) is safe or not based on the deployment of RPKI that we talked about in our BGP Security session. It is one of the core components within BGPsec, which is still not widely deployed. Check it out: https://isbgpsafeyet.com/

Above is a really high-level and gentle intro to Lattice crypto. We have never talked about Elliptic Curve in our class, let alone this Lattice monster. But, I hope you could spend 5 min to give the medium blog a read. You will see the “hard problems” we talked about for asymmetric crypto and why it is really hard to prove that those problems are actually hard. Yet, Lattice crypto takes a different approach and somehow it is post-quantum safe, as I have been told. You probably can guess now that some of the “hard problems” are not post-quantum safe, although RSA might still be secure if we use a 32GB private key…

Anyway, sorry for this long due post. Stay safe~
