rcgen

Simple Rust library to generate X.509 certificates.

extern crate rcgen;
use rcgen::generate_simple_self_signed;
let subject_alt_names = vec!["hello.world.example".to_string(),
	"localhost".to_string()];

let cert = generate_simple_self_signed(subject_alt_names).unwrap();
// The certificate is now valid for localhost and the domain "hello.world.example"
println!("{}", cert.serialize_pem().unwrap());
println!("{}", cert.serialize_private_key_pem());

Trying it out with openssl

You can do this:

cargo run
openssl x509 -in certs/cert.pem -text -noout

For debugging, pasting the PEM formatted text to this service is very useful.

Trying it out with quinn

You can use rcgen together with the quinn crate. The whole set of commands is:

cargo run
cd ../quinn
cargo run --example server -- --cert ../rcgen/certs/cert.pem --key ../rcgen/certs/key.pem ./
cargo run --example client -- --ca ../rcgen/certs/cert.der https://localhost:4433/README.md
