function chilkatExample() {

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

    var crypt = new chilkat.Crypt2();

    //  Choose the hash algorithm.
    //  Can be  "sha1", "sha256", "sha384", "sha512", "md2", "md5", "haval", "ripemd128", "ripemd160","ripemd256", or "ripemd320".

    hashBytes = crypt.HashFile("qa_data/jpg/starfish.jpg");

    //  Let's examine the hash as a hex string.
    var sb = new chilkat.StringBuilder();
    sb.AppendEncoded(hashBytes,"hex");
    console.log("SHA256 hash = " + sb.GetAsString());
