Generate an RSA Key and Save to Encrypted PEM

See more RSA Examples

Demonstrates how to generate an RSA key and save to an encrypted PEM file. Rust

let rsa = chilkat::Rsa::new();

// Generate a 2048-bit key.
let priv_key = chilkat::PrivateKey::new();
if rsa.gen_key(2048, &priv_key).is_err() {
    println!("{}", rsa.last_error_text());
    return;
}

let password = "secret".to_string();
// Saving to a relative path (from the current working directory of the process).
let mut path = "rsaKeys/myTestRsaPrivate.pem".to_string();
// Encrypt the PEM using 256-bit AES encryption.
priv_key.set_pkcs8_encrypt_alg("aes256");
if priv_key.save_pkcs8_encrypted_pem_file(&password, &path).is_err() {
    println!("{}", priv_key.last_error_text());
    return;
}

// 

// We can also save the public key.
// There is no need to encrypt public keys.
let pub_key = chilkat::PublicKey::new();
let _ = priv_key.to_public_key(&pub_key);

path = "rsaKeys/myTestRsaPublic.pem".to_string();
// Choose PKCS1 or PKCS8
// We'll choose PKCS8.
let prefer_pkcs1 = false;
if pub_key.save_pem_file(prefer_pkcs1, &path).is_err() {
    println!("{}", pub_key.last_error_text());
    return;
}

// 

println!("Success.");
