You need to use binary mode for the file. Also you better convert both key and data to UTF8 else non-ANSI characters will get emasculated.

#include <Crypt.au3>
$admin_pass1 = StringToBinary(InputBox("admin", "pass", "", "*"),4)
        $file = FileOpen("AKEY.Data", 18)
        FileWrite($file, _Crypt_EncryptData($admin_pass1, StringToBinary("Izdroid",4), $CALG_RC4))
        FileClose($file)
        MsgBox(64, "^^", "done", 15)


Func pass()
    $file = FileOpen("AKEY.Data", 0);should changed to 16
    $pass = FileRead($file)
    FileClose($file)
    $pass = BinaryToString(_Crypt_DecryptData($pass, StringToBinary("Izdroid",4), $CALG_RC4))

    Return $pass
EndFunc   ;==>pass

But you still read the file as text, not binary!
