I assume that the big difference is in the way that we are computing the SHA hash. The Java version uses the native MessageDigest class, which allows it stick to the bytes; but, I'm using the CF-native hash() function which outputs a string, which I then have to decode back into a byte array. I don't know if that's the bottleneck, but it seems like the most obvious difference to me.

I could try using the MessageDigest and see what kind of a performance differences it makes.

Hmmm, just tried dropping in the MessageDigest:

var salt = generateEntropy( tokenLength );
var text = ( input & salt );


var bytes = MessageDigestClass.getInstance( "sha-256" ).digest( charsetDecode( text, "utf-8" ) );

var result = BigIntegerClass
	.init( bytes )
	.toString( 36 )
	.right( -2 )
;

return( result );

And, it's only a few seconds faster. Clearly that is not the bottleneck. 🤔
