Using existing source codes, we will be writing a code to work backwards to decrypt files other than encrypting (our existing code)
PID Generating, we (or at least PHP) will use inputs from file by
hexdec(bin2hex(strrev(file_get_contents($file, NULL, NULL, 0x..., 0x...)))); //
hexdec(bin2hex(strrev(file_get_contents($file, NULL, NULL, 0x..., 0x...)))); //
hexdec(bin2hex(strrev(file_get_contents($file, NULL, NULL, 0x..., 0x...)))); //
