Actually, this is the only problem. In the original code, 'io.lines' is
not reading lines, but blocks of 4K. That format should have no problems
with binary data. So, the code could be like this:

  if arg[1] then
+   local file = assert( (arg[1], 'rb'))
    local x = sha2.new256()
-   for b in io.lines(arg[1], 2^12) do
+   for b in file:lines(2^12) do
+   file:close()
