Create JWT using a Certificate's Private Key

See more JSON Web Token (JWT) Examples

Demonstrates how to create a JWT using a certificate's private key. Rust

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Demonstrates how to create a JWT using an certificate's private key.

let cert = chilkat::Cert::new();

// Load an ECC private key from a PEM file.
if cert.load_pfx_file("c:/temp/myPfx.pfx", "pfxPassword").is_err() {
    println!("{}", cert.last_error_text());
    return;
}

let jwt = chilkat::Jwt::new();

// Build the JOSE header
let jose = chilkat::JsonObject::new();
// Note: The IsEcdsa function was added in Chilkat v10.1.0
if cert.is_ecdsa() {
    // Use ES256.  Pass the string "ES384" or "ES512" to use ECC with SHA-384 or SHA-512.
    let _ = jose.append_string("alg", "ES256");
} else {
    // Probably RSA...
    // Use RS256.  Pass the string "RS384" or "RS512" to use RSA with SHA-384 or SHA-512.
    let _ = jose.append_string("alg", "RS256");
}

let _ = jose.append_string("typ", "JWT");

// Now build the JWT claims (also known as the payload)
let claims = chilkat::JsonObject::new();
let _ = claims.append_string("iss", "http://example.org");
let _ = claims.append_string("sub", "John");
let _ = claims.append_string("aud", "http://example.com");

// Set the timestamp of when the JWT was created to now.
let cur_date_time = jwt.gen_numeric_date(0);
let _ = claims.add_int_at(-1, "iat", cur_date_time);

// Set the "not process before" timestamp to now.
let _ = claims.add_int_at(-1, "nbf", cur_date_time);

// Set the timestamp defining an expiration time (end time) for the token
// to be now + 1 hour (3600 seconds)
let _ = claims.add_int_at(-1, "exp", cur_date_time + 3600);

// Produce the smallest possible JWT:
jwt.set_auto_compact(true);

// Create the JWT token.
let token = jwt.create_jwt_cert(&jose.emit().unwrap_or_default(), &claims.emit().unwrap_or_default(), &cert).unwrap_or_default();

println!("{}", token);
