pub struct Certificate(pub Vec<u8>);
Expand description

This type contains a single certificate by value.

The certificate must be in DER-encoded X.509 format.

A common format for storing certificates is PEM. PEM certificates are commonly stored in files with a .pem, .cer or .crt suffix, and look like this:

-----BEGIN CERTIFICATE-----
<base64-encoded certificate content>
-----END CERTIFICATE-----

The rustls-pemfile crate can be used to parse PEM files. The rcgen crate can be used to generate certificates and private keys.

Examples

Parsing a PEM file to extract DER-encoded certificates:

use std::fs::File;
use std::io::BufReader;
use rustls::Certificate;

fn load_certificates_from_pem(path: &str) -> std::io::Result<Vec<Certificate>> {
    let file = File::open(path)?;
    let mut reader = BufReader::new(file);
    let certs = rustls_pemfile::certs(&mut reader)?;

    Ok(certs.into_iter().map(Certificate).collect())
}
