Question

Update: I solved the decoding problem, thanks to pimvdb

Follows the solution (in PHP):

$len = $masks = $data = $decoded = n         


        

Answer 1

Decode solution (thanks to @pimvdb):

$len = $masks = $data = $decoded = null;

$len = ord ($buffer[1]) & 127;

if ($len === 126) {
  $masks = substr ($buffer, 4, 4);
  $data = substr ($buffer, 8);
}
else if ($len === 127) {
  $masks = substr ($buffer, 10, 4);
  $data = substr ($buffer, 14);
}
else {
  $masks = substr ($buffer, 2, 4);
  $data = substr ($buffer, 6);
}

for ($index = 0; $index < strlen ($data); $index++) {
  $decoded .= $data[$index] ^ $masks[$index % 4];
}
