Socket TLS Mutual Authentication (Client-Side Certificate)

See more Socket/SSL/TLS Examples

This example demonstrates how to provide a client-side certificate, also known as "two-way authentication" or "mutual authentication" for servers that require a client certificate. Rust

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

let sock = chilkat::Socket::new();

// Set the certificate to be used for mutual TLS authentication
// (i.e. sets the client-side certificate for two-way TLS authentication)
if sock.set_ssl_client_cert_pfx("/home/bob/pfxFiles/myClientSideCertWithPrivateKey.pfx", "pfxPassword").is_err() {
    println!("{}", sock.last_error_text());
    return;
}

// Note: The certificate used for the client-side of TLS mutual authentication
// must have the associated private key available. (.pfx/.p12 files typically store both
// the certificate and associated private key.)

// Establish the connection using the socket object (with client certificate authentication).
let b_tls = true;
let port = 443;
let max_wait_ms = 5000;
if sock.connect("www.example.com", port, b_tls, max_wait_ms).is_err() {
    println!("Connect Failure Error Code: {}", sock.connect_fail_reason());
    println!("{}", sock.last_error_text());
    return;
}

// At this point, the Socket object is connected and authenticated using the client-side cert
