  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);
    }
  }

  public static void main(String argv[])
  {
    //  Starting in v9.5.0.49, all Chilkat classes can be unlocked at once at the beginning of a program
    //  by calling UnlockBundle.  It requires a Bundle unlock code.
    CkGlobal chilkatGlob = new CkGlobal();
    boolean success = chilkatGlob.UnlockBundle("Anything for 30-day trial.");
    if (success != true) {
        System.out.println(chilkatGlob.lastErrorText());
        return;
    }

    CkPem pem = new CkPem();

    String pemPassword = "secret";

    //  To load a PEM file containing encrypted private keys, simply
    //  provide the password.
    success = pem.LoadPemFile("/Users/chilkat/testData/pem/pemContainingEncryptedPrivateKeys.pem",pemPassword);
    if (success != true) {
        System.out.println(pem.lastErrorText());
        return;
    }

    CkFileAccess fac = new CkFileAccess();
    String pemText = fac.readEntireTextFile("/Users/chilkat/testData/pem/pemContainingEncryptedPrivateKeys.pem",pemPassword);

    //  To load a PEM from a string, call LoadPem instead of LoadPemFile:
    success = pem.LoadPem(pemText);
    if (success != true) {
        System.out.println(pem.lastErrorText());
        return;
    }

    //  A few notes:
    //  The PEM may contain both private keys and certificates (or anything else).
    //  The password is utilized for whatever content in the PEM is encrypted.
    //  It is OK to have both encrypted and non-encrypted content within a given PEM.

    //  PEM private keys can be encrypted in different formats.  The LoadPem and LoadPemFile
    //  methods automatically handle the different formats.
    //  One format is PKCS8 and is indicated by this delimiter within the PEM:

    //  -----BEGIN ENCRYPTED PRIVATE KEY-----
    //  MIICoTAbBgkqhkiG9w0BBQMwDgQIfdD0zv24lgkCAggABIICgE0PdHJmRbNs6cBX
    //  ...

    //  Another format, we'll call "passphrase" looks like this in the PEM:
    //  -----BEGIN RSA PRIVATE KEY-----
    //  Proc-Type: 4,ENCRYPTED
    //  DEK-Info: DES-EDE3-CBC,A4215544D11C5D0C
    // 
    //  paqy9XRexcSjurHfG0xhCaUD0HrvIdhuC0CbRxxxeMlkLaV6+uT80rBxt2AaibWG
    //  ...

    //  Show the bit length of each private key:
    int i;
    int numPrivateKeys = pem.get_NumPrivateKeys();
    if (numPrivateKeys == 0) {
        System.out.println((("Error: Expected the PEM to contain private keys.")));
        return;
    }

    for (i = 1; i <= numPrivateKeys; i++) {
        CkPrivateKey privKey = pem.GetPrivateKey(i - 1);
        System.out.println(i + ": " + privKey.get_BitLength() + " bits");

    }
