    crypt.CryptAlgorithm = "3des";

    //  encryption, and the input for decryption.
    //  It may be "hex", "url", "base64", or "quoted-printable".
    crypt.EncodingMode = "hex";

    //  Let's create a secret key by using the MD5 hash of a password.

    //  Encrypt
    var encStr = crypt.EncryptStringENC("The quick brown fox jumped over the lazy dog");

    //  Now decrypt:
