Befuddler is the name of my latest creation. It’s an application that’s used to modify the signature of a file, as well as its file extension, to prevent paranoid corporate/government e-mail filters from dropping your attachments (such as ZIP files.) Just pass your file through this before you send it. The recipient on the other side will also have to do the same to reverse the changes.
The program does not change the size of the file, nor does it modify the whole thing – just the first few bytes – so it runs very fast on even the largest of files. You can download a copy below. It was tested on Windows XP and Windows 7.
