SFTP Public-Key Authentication

See more SFTP Examples

Demonstrates how to authenticate with an SSH/SFTP server using publickey authentication. Rust

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

let sftp = chilkat::SFtp::new();

// Set some timeouts, in milliseconds:
sftp.set_connect_timeout_ms(5000);
sftp.set_idle_timeout_ms(15000);

// Connect to the SSH server.  
// The standard SSH port = 22
// The hostname may be a hostname or IP address.
let hostname = "sftp.example.com".to_string();
let port = 22;
if sftp.connect(&hostname, port).is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

let key = chilkat::SshKey::new();

// Load a PEM file into a string variable:
// (This does not load the PEM file into the key.  The LoadText
// method is a convenience method for loading the full contents of ANY text
// file into a string variable.)
let Ok(priv_key) = key.load_text("myPrivateKey.pem") else {
    println!("{}", key.last_error_text());
    return;
};

// Load a private key from a PEM string:
// (Private keys may be loaded from OpenSSH and Putty formats.
// Both encrypted and unencrypted private key file formats
// are supported.  This example loads an unencrypted private
// key in OpenSSH format.
if key.from_open_ssh_private_key(&priv_key).is_err() {
    println!("{}", key.last_error_text());
    return;
}

// Authenticate with the SSH server.  Chilkat SFTP supports
// both password-based authenication as well as public-key
// authentication.  
if sftp.authenticate_pk("myLogin", &key).is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

println!("{}", sftp.last_error_text());
println!("Public-Key Authentication Successful!");
