Crate rcgen

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);
println!("{}", cert.serialize_pem());
println!("{}", cert.serialize_private_key_pem());

Structs

Certificate	A self signed certificate together with signing keys
CertificateParams	Parameters used for certificate generation
CustomExtension	A custom extension of a certificate, as specified in RFC 5280
DistinguishedName	Distinguished name used e.g. for the issuer and subject fields of a certificate
SignatureAlgorithm	Signature algorithm type

Enums

BasicConstraints	The path length constraint (only relevant for CA certificates)
DnType	The attribute type of a distinguished name entry
IsCa	Whether the certificate is allowed to sign other certificates

Statics

PKCS_ECDSA_P256_SHA256	ECDSA signing using the P-256 curves and SHA-256 hashing as per RFC 5758
