Similar to what is listed here, http://datapigtechnologies.com/blog/index.php/hack-into-a-protected-excel-2007-or-2010-workbook/, is there a way to remove the password from an XLS (Excel 2003) document? Note that I am not asking for ways in which to crack or brute-force the password. I know that Excel 2003 uses RC4 for the encryption scheme. However, it does not store files in the same zip like structure that 2007 and 2010 does.
Additional Updates: This is for a forgotten "File Open" and not VBA password. I would be happy to hex edit the file too if I could find the specifications for where the password was stored. An example used for VBA file removal is listed here, http://gbanik.blogspot.co.uk/2010/08/understanding-excel-file-internals.html, and this is something sort of like what I am looking for except for the "File Open" password.
