(JavaScript) SSH Authentication using X.509 Certificates

See more SSH Examples

Note: See X.509v3 Certificates for SSH Authentication for more information.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

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

var ssh = new CkSsh();

var hostname = "ssh.example.com";
var port = 22;
success = ssh.Connect(hostname,port);
if (success !== true) {
    console.log(ssh.LastErrorText);
    return;
}

// Load the cert + private key from a .pfx.
// Note: Chilkat provides methods for loading certs and private keys from many sources, including smart cards and USB tokens (HSM's)
var cert = new CkCert();
success = cert.LoadPfxFile("qa_data/pfx/example.pfx","pfx_password");
if (success !== true) {
    console.log(cert.LastErrorText);
    return;
}

// Get the cert's private key (as PEM) to be used for SSH authentication.
// (The public key is installed on the server.)
var privKeyPem = cert.GetPrivateKeyPem();
if (cert.LastMethodSuccess == false) {
    console.log(cert.LastErrorText);
    return;
}

var key = new CkSshKey();

// Load a private key from a PEM string:
success = key.FromOpenSshPrivateKey(privKeyPem);
if (success !== true) {
    console.log(key.LastErrorText);
    return;
}

// Authenticate with the SSH server.
success = ssh.AuthenticatePk("myLogin",key);
if (success !== true) {
    console.log(ssh.LastErrorText);
    return;
}

console.log("Public-Key Authentication Successful!");
