Expand description

Rust X.509 certificate generation utility

This crate provides a way to generate self signed X.509 certificates.

The most simple way of using this crate is by calling the generate_simple_self_signed function. For more customization abilities, we provide the lower level Certificate::from_params function.

Example

extern crate rcgen;
use rcgen::generate_simple_self_signed;
// Generate a certificate that's valid for "localhost" and "hello.world.example"
let subject_alt_names = vec!["hello.world.example".to_string(),
	"localhost".to_string()];

let cert = generate_simple_self_signed(subject_alt_names).unwrap();
println!("{}", cert.serialize_pem().unwrap());
println!("{}", cert.serialize_private_key_pem());
