Rust Requires Chilkat v11.0.0+

SFTP Auth Failure Reason (AuthenticatePwPk)

See more SFTP Examples

This example demonstrates how to determine the failure reason for the case where both a password and private key are required for authentication. If authentication fails, was it because of an invalid private key, or an invalid password? Rust

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

// Load a private key to be used for SSH authentication.
let key = chilkat::SshKey::new();
key.set_password("key_password");

if key.from_open_ssh_private_key(&key.load_text("qa_data/my_private_key_file").unwrap_or_default()).is_err() {
    println!("{}", key.last_error_text());
    return;
}

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

if sftp.connect("sftp.example.com", 22).is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

// Authenticate using both a password and private key.
if sftp.authenticate_pw_pk("myLogin", "myPassword", &key).is_ok() {
    println!("Authentication is successful!");
    return;
}

// If we get here, it means the authentication failed.
// Examine the last JSON data..

let json = chilkat::JsonObject::new();
sftp.get_last_json_data(&json);

json.set_emit_compact(false);

// This is the JSON if the key is correct, but the password is incorrect:

// {
//   "public_key_type": "rsa",
//   "partialAuthResult": "publickey success. continue to authenticate with password...",
//   "authResult": "failed",
//   "authFailReason": "Password is incorrect"
// }

// This is the JSON if the key is incorrect.  We won't know if the password is also incorrect until
// the key is made correct so that authentication proceeds to check the password.

// {
//   "public_key_type": "rsa",
//   "authResult": "failed",
//   "authFailReason": "Key is incorrect"
// }

// To get the authResult anbd authFailReason:
println!("authResult: {}", json.string_of("authResult").unwrap_or_default());
println!("authFailReason: {}", json.string_of("authFailReason").unwrap_or_default());
