The state of the post-quantum Internet

What this post added

This post provides an update on the state of post-quantum cryptography (PQC) adoption and its implications for the Internet. It highlights the increasing percentage of TLS 1.3 connections secured with PQC, the timelines for quantum computer development and their threat to current cryptography, and the two main migration paths: key agreement and signatures/certificates. It also clarifies that symmetric cryptography is already post-quantum secure. The post emphasizes the urgency of migration due to the 'harvest now, decrypt later' threat.
