This week, Cloudflare is sharing a series of blog posts about their work involving cryptography during Halloween season. They will discuss various projects such as Privacy Pass, Post-quantum Cryptography experiment, cfnts (Cloudflare's implementation of NTS in Rust), DNS Encryption Explained, Delegated Credentials for TLS, and keeping private keys secure from memory disclosure attacks. These milestones are made possible through partnerships with various organizations working together to build a better Internet.
