Caddy's automagic TLS features, now for your own Go programs, in one powerful and easy-to-use library! CertMagic is the most mature, robust, and powerful ACME client integration for Go, and perhaps ever. With CertMagic, you can add one line to your Go application to serve securely over TLS, without ever having to touch certificates. Just a line of code will serve your HTTP router mux over HTTPS, complete with HTTP->HTTPS redirects. It obtains and renews the TLS certificates. It staples OCSP responses for greater privacy and security. As long as your domain name points to your server, CertMagic will keep its connections secure. Compared to other ACME client libraries for Go, only CertMagic supports the full suite of ACME features, and no other library matches CertMagic's maturity and reliability. Written in Go, a language with memory-safety guarantees. Powered by ACMEz, the premier ACME client library for Go. All libdns DNS providers work out-of-the-box.
