SFTP Public-Key Authentication (id_ed25519)

See more SFTP Examples

Demonstrates how to authenticate with an SSH/SFTP server using publickey authentication with an Ed25519 private key (id_ed25519). Rust

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

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

// The id_ed25519 file should contain something like this:
// (You can open it in a text editor..)

// -----BEGIN OPENSSH PRIVATE KEY-----

let Ok(priv_key_text) = key.load_text("c:/temp/id_ed25519") else {
    println!("{}", key.last_error_text());
    return;
};

// If your private key was saved encrypted, then you'll need the password.
// In this example, the password "blahblah" is valid for the above key -- which is a real Ed25519 key generated/saved from puttygen.
key.set_password("blahblah");

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

let hostname = "sftp.example.com".to_string();
let port = 22;
