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

    var crypt = new chilkat.Crypt2();

    // Set the name of the hash algorithm.
    // Other choices include "sha1", "sha256", "sha384", "sha512", "md2", "md5", and "haval".
