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

    var crypt = new chilkat.Crypt2();

    //  Set properties for PBES2 encryption:

    //  When the encryption algorithm is set to "pbes2",
    //  Chilkat will automatically derive the actual secret key using PBKDF2 and
    //  the specified paramters: password, salt, iteration count, hash function, and desired key length.

    crypt.CryptAlgorithm = "pbes2";
    crypt.PbesPassword = "mySecretPassword";

    //  Set the underlying PBE algorithm (and key length):
    crypt.PbesAlgorithm = "aes";
    crypt.KeyLength = 256;

    crypt.SetEncodedIV("000102030405060708090A0B0C0D0E0F","hex");

    //  Give it some salt:
    crypt.SetEncodedSalt("0102030405060708","hex");

    //  A higher iteration count makes the algorithm more
    //  computationally expensive and therefore exhaustive
    //  searches (for breaking the encryption) is more difficult:
    crypt.IterationCount = 1024;

    //  A hash algorithm needs to be set for PBES2:
    crypt.HashAlgorithm = "sha256";

    //  Indicate that the encrypted bytes should be returned
    //  as a hex string:
    crypt.EncodingMode = "hex";

    var plainText = "To be encrypted.";

    var encryptedText = crypt.EncryptStringENC(plainText);

    console.log(encryptedText);

    //  Now decrypt:
