var success = false;

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

var dsa = new CkDsa();

// Load a DER private key.
success = dsa.FromDerFile("dsa_priv.der");
if (success !== true) {
    console.log(dsa.LastErrorText);
    return;
}

var pemStr;

// Save to unencrypted PEM:
pemStr = dsa.ToPem();
success = dsa.SaveText(pemStr,"dsa_priv.pem");
if (success !== true) {
    console.log(dsa.LastErrorText);
    return;
}

// Save to encrypted PEM:
pemStr = dsa.ToEncryptedPem("myPassword");
success = dsa.SaveText(pemStr,"dsa_privEncrypted.pem");
if (success !== true) {
    console.log(dsa.LastErrorText);
    return;
}

console.log("Finished!");
