Do the ChaCha: better mobile performance with cryptography

What's this blog post about?

CloudFlare has introduced a new feature that improves mobile performance by adding support for the ChaCha20-Poly1305 cipher suites, making it the first major site to do so apart from Google services. This enhances security and speeds up mobile browsing experience on sites using CloudFlare. The protocol used for encrypting HTTPS connections is Transport Layer Security (TLS), which allows new encryption algorithms or ciphers to be proposed and added to its specification. The new cipher suites use the ChaCha20 stream cipher, designed to provide 256-bit security, and Poly1305 authenticator for authentication. These are considered more secure than standard choices and provide a battery-friendly alternative to AES for mobile devices.
