# Natas 8
When the webpage first loads, there is nothing interesting except the view sourcecode, so lets go there immediately
In the source code itself, once again like Natas 6, there is some interesting php code
```php
";
} else {
print "Wrong secret";
}
}
?>
```
The string `return bin2hex(strrev(base64_encode($secret)));` simply encodes it in base64, reverses the string and converts it to hexadecimal. By reverse engineering this in CyberChef
We obtain the password
Entering this into the Input gives the following
Thus the password is `ZE1ck82lmdGIoErlhQgWND6j2Wzz6b6t`
