Encrypting as much web traffic as possible to prevent data theft and other tampering is a critical step toward building a safer, better Internet. We’re proud to be the first Internet performance and security company to offer SSL protection free of charge.
HTTPS isn’t what it used to be. It’s faster, more secure, and used by more websites than ever before. SSL enables HTTP/2, which has the potential to make websites up to two times faster with no changes to existing codebases. Modern TLS also includes performance-oriented features like session resumption, OCSP stapling, and elliptic curve cryptography that uses smaller keys (resulting in a faster handshake). TLS 1.3 reduces latency even further and removes insecure features of TLS making HTTPS more secure and performant than any previous version of TLS and its non-secure counterpart, HTTP.
Cloudflare has even worked to improve the performance of OpenSSL. We implemented ChaCha20-Poly1305, a cipher suite that runs three times faster than AES-128-GCM on mobile devices. We care about performance.
