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

This type contains a private key by value.

The private key must be DER-encoded ASN.1 in either PKCS#8, PKCS#1, or Sec1 format.

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

-----BEGIN PRIVATE KEY-----
<base64-encoded private key content>
-----END PRIVATE KEY-----

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

Examples

Creating a PrivateKey from a PEM file containing a PKCS8-encoded private key using the rustls_pemfile crate:

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

fn load_private_key_from_file(path: &str) -> Result<PrivateKey, Box<dyn std::error::Error>> {
    let file = File::open(&path)?;
    let mut reader = BufReader::new(file);
    let mut keys = rustls_pemfile::pkcs8_private_keys(&mut reader)?;

    match keys.len() {
        0 => Err(format!("No PKCS8-encoded private key found in {path}").into()),
        1 => Ok(PrivateKey(keys.remove(0))),
        _ => Err(format!("More than one PKCS8-encoded private key found in {path}").into()),
    }
}
