It takes two to ChaCha (Poly)

The blog post discusses the adoption of ChaCha20-Poly1305, an AEAD (Authenticated Encryption with Additional Data) cipher suite, on the web. It highlights how this cipher suite was initially implemented by Cloudflare to provide better performance and security for mobile users. The post also reviews the history of ChaCha20-Poly1305, its standardization process, and its importance for the future of the web. Additionally, it compares the performance of ChaCha20-Poly1305 with other standard AEADs such as AES-GCM. The post concludes by stating that Cloudflare is committed to pushing the envelope in terms of TLS performance and availability of secure cipher suites, actively participating in the development of TLS 1.3 and open source initiatives.
