BitXOR with 16 Bytes?

[p)(d]

i try to xor a lot of 16byte binarys, but it seems that bitxor only use 8bit?

this is a part of my code:

$input = Binary("0x00112233445566778899AABBCCDDEEFF")

$key = Binary("0x9E3D486739F7E51CDAED76CCE36AD732")

$output = Binary (BitXOR($input, $key))

msgbox(1,"",$output)

the output is: 0x9E000000

any idee?

It get: 0x9E2C6A547DA2836B5274DC772FB739CD

$input = Binary("0x00112233445566778899AABBCCDDEEFF")
$key = Binary("0x9E3D486739F7E51CDAED76CCE36AD732")
$output = "0x"
For $n = 1 To 16
    $input_int = Int(BinaryMid($input, $n, 1))
    ConsoleWrite("$input_int = " & $input_int & @LF)
    $key_int = Int(BinaryMid($key, $n, 1))
    ConsoleWrite("$key_int = " & $key_int & @LF)
    $XOR_int = BitXOR($input_int, $key_int)
    ConsoleWrite("$XOR_int = " & $XOR_int & @LF)
    $output &= Hex($XOR_int, 2)
    ConsoleWrite("$output = " & $output & @LF)
Next
$output_bin = Binary($output)
ConsoleWrite(@LF & "Final $output_bin = " & $output_bin & @LF)

BitXor() operates on bytes as unsigned integers, hence the conversion. Variable $output is assembled as a string of hex, which requires a final conversion back to binary.

thanx a lot!
