FAQ

Can anyone modify the content of a signed file?

Any modification in a signed file except adding new signature and adjusting signatures, will cause invalidation of existed signatures or destroy of whole file structure. So do not worry about someone to modify the content of a signed file after your signing.

By default, while opening a complex signed file( .wds file), MDSS client program will launch suitable application to open a copy of the Original File. Also, you can do this by hand by select "File > Extract Orginal File >Extract and Open Original File".

You can only get a copy of original file from the signed file. To do that, select "File > Extract Original File > Extract and Save Original File".
