Solution​

okay so the first thing that will come to our mind while visiting the page will be clicking that View sourcecode button.
when you will visit that page you will find an encoded secret, you have to decode it
but we are given a function in php to encode secret ... so to decode it we will implement that in reverse order

function encodeSecret($secret) {
    return bin2hex(strrev(base64_encode($secret)));
}

bin2hex(strrev(base64_encode($secret)) produced 3d3d516343746d4d6d6c315669563362
reverse these steps to get the secret

make sure you have php installed on your pc/laptop ... then execute following commands.

shubhamdchhatbar@shubhams-MacBook-Air ~ % php -a
Interactive shell

php > echo base64_decode(strrev(hex2bin('3d3d516343746d4d6d6c315669563362')));
