Javascript for SHA-256 Hash

<script type="text/javascript" language="javascript">

function sha256Hash()
{
	document.crypt2.UnlockComponent("Anything goes here.");
	
	document.crypt2.Charset = "iso-8859-1";
	document.crypt2.HashAlgorithm = "sha-256";
	document.crypt2.EncodingMode = "hex";
	
	document.form1.etx.value = 
			document.crypt2.HashStringENC(document.form1.etx.value);
}

</script>

The crypt2.HashStringENC method computes a hash value for a text string. The text is first (internally) converted to the crypt2.Charset prior to computing the hash. In this case, the Charset is set to "iso-8859-1" indicating that we want to hash the 1-byte per character encoding of a typical Western-European language string. If it were set to "unicode" for example, it would hash a string containing 2 bytes/char Unicode (and thus arrive at a different hash value).
