Rustls Gains OpenSSL and Nginx Compatibility
The Rustls TLS library can now be used with Nginx via an OpenSSL compatibility layer. This means that Nginx users can switch from OpenSSL to Rustls with minimal effort - users can simply swap in a new TLS library without needing to modify or recompile Nginx.
We have targeted Nginx versions greater than 1.18 on Ubuntu 22.04 or newer for initial support. Here's how easy it is to get going on x86_64 Ubuntu Linux 22.
