Hi,<br><br>Most probably, the bug is related to the way the file size modulo is computed, as the algorithm behavior has nothing to do with file types.<br><br>Could you try XLS files with different sizes?<br>Could you provide the XLS file or, if not possible, the size of your XLS file?<br>

That should definitely not happen. The fact it is an XLS file should
also make no difference at all. Perhaps there is a bug with either
reading or writing the file modulo?<br>
<br>
David, would you be able to provide some guidance?<br>

赵鲁,<br>
<br>
I am forwarding your message to the AES Crypt mailing list to see if
others might be able to help you. However, it's not entirely clear
what the issue is, so can you clarify it further?<br>
<br>
Thanks,<br>
Paul<br>
