Javascript for Decoding Base64

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

function decodeBase64()
{
	document.form1.etx.value = 
		document.crypt2.BytesToString(
			document.crypt2.Decode(document.form1.etx.value,"base64"),"utf-8");
}

</script>

The crypt2.Decode method decodes the Base64 text to binary bytes. The bytes are then converted to a utf-8 string and the textarea is updated.

About the Chilkat ActiveX Components for Client-Side Javascript / AJAX

The Chilkat ActiveX components are packaged in digitally-signed .cab files to ensure integrity and authenticity. The components are safe-for-scripting. When a Chilkat ActiveX detects that it is running in a browser, all local filesystem read/write functionality is disabled.
