Rust Requires Chilkat v10.1.2+

Secure FTP with Client Certificate

See more FTP Examples

Chilkat FTP2 provides the ability to use a client certificate with secure FTP (implicit or explicit SSL/TLS). This example demonstrates how to load a certificate from a .pfx and use it as the client-side SSL cert. Note: Client-side certificates are only needed in situations where the server demands one. Rust

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

let ftp = chilkat::Ftp2::new();

ftp.set_hostname("ftp.example.com");
ftp.set_port(21);
ftp.set_username("test");
ftp.set_password("test");

// This example will use explict TLS/SSL.
// Establish an explicit secure channel after connection
// on the standard FTP port 21.
ftp.set_auth_tls(true);

// The Ssl property is for establishing an implicit SSL connection
// on port 990.  Because this example uses explicit SSL, it 
// should remain false.
ftp.set_ssl(false);

// Load a certificate from a .pfx
// A PFX may contain several certs, including the certificates
// in a chain of authority.
let cert_store = chilkat::CertStore::new();
let password = "***".to_string();
// Load the certs from a PFX into an in-memory certificate store:
if cert_store.load_pfx_file("chilkat.pfx", &password).is_err() {
    println!("{}", cert_store.last_error_text());
    return;
}

// Find the desired certificate.
let json_cn = chilkat::JsonObject::new();
let _ = json_cn.update_string("CN", "cert common name");

let cert = chilkat::Cert::new();
if cert_store.find_cert(&json_cn, &cert).is_err() {
    println!("Certificate not found!");
    return;
}

// Use this certificate for our secure (SSL/TLS) connection:
let _ = ftp.set_ssl_client_cert(&cert).is_ok();

// Connect and login to the FTP server.  The connection is 
// made secure because of the AuthTls setting.
if ftp.connect().is_err() {
    println!("{}", ftp.last_error_text());
    return;
} else {
    // LastErrorText contains information even when
    // successful. This allows you to visually verify
    // that the secure connection actually occurred.
    println!("{}", ftp.last_error_text());
}

println!("Secure FTP Channel Established!");

// Do whatever you're doing to do ...
// upload files, download files, etc...

// .....
// .....

let _ = ftp.disconnect().is_ok();
