Password_Digest = Base64 (SHA-1 ( nonce + created + SHA-1 (password) ) )

Demonstrates how to compute:

Password_Digest = Base64 (SHA-1 ( nonce + created + SHA-1 (password)))

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

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

    String password = "secret";

    CkCrypt2 crypt = new CkCrypt2();
    crypt.put_HashAlgorithm("SHA-1");

    // Generate a 16-byte random nonce
    CkPrng prng = new CkPrng();
    CkBinData bd = new CkBinData();
    prng.GenRandomBd(16,bd);

    // Get the current date/time in a string with this format: 2010-06-08T07:26:50Z
    CkDateTime dt = new CkDateTime();
    dt.SetFromCurrentSystemTime();

    bd.AppendString(created,"utf-8");

    // This example wishes to calculate a password digest like this:
    // Password_Digest = Base64 ( SHA-1 ( nonce + created + SHA-1(password) ) )

    // First SHA-1 digest the password...
    String passwordSha1 = crypt.hashStringENC(password);
    // Append the 20 binary bytes of the SHA1 hash to bd, which already contains the nonce and created date/time.
    bd.AppendEncoded(passwordSha1,"base64");

    String passwordDigest = crypt.hashBdENC(bd);

    System.out.println("Base64 password digest = " + passwordDigest);
