Please find below snippet , we have to convert to Coldfusion tags ,any one help me.

<script type="text/javascript">
var epochTime = "1605070736";
var Digest = computeDigest();
function computeDigest()
{
var hmac = Crypto.HMAC(Crypto.SHA256, epochTime, "1308302020102915214099263166", { asBytes: true });
var base64String = Crypto.util.bytesToBase64(Crypto.HMAC(Crypto.SHA256, epochTime, "AKI1308302020102915214099263166", { asBytes: true }));
return base64String;
}
</script>
