{"id":"handshake","authentication-response":"1D214EF554123712A0DC9BCF003C27F4"}
{"id":"handshake","authentication-passed":true}


Ok, I got it.  Just answering for anyone else who stumbles here.  While not documented, RFB mirrors each bit.  Using the key of all B's, I was able to get my result, as B is a palindrome.
