JavaScript

var success = false;

var cert = new CkCert();

// LoadFromFile will load virtually any certificate format file.
// It will auto-recognize the format and load appropiately.
// In this case, load a PEM format certificate and convert to DER.
success = cert.LoadFromFile("/Users/chilkat/testData/pem/chilkat.pem");
if (success !== true) {
    console.log(cert.LastErrorText);
    return;
}

success = cert.ExportCertDerFile("chilkat.der");
if (success !== true) {
    console.log(cert.LastErrorText);
    return;
}

console.log("Converted certificate from PEM to DER format.");
