Hi Scott,

This is the behaviour I would have expected. Your user opens the web app
and gets the XL file. An image of that file is now residing in the user's
browser (which doesn't have the key on it). Therefore the user isn't able
to save a signed version of your file.

Or am I missing the point?

Regards,

Peter Beach

We have a web application that generates an Excel file. The file has
macros in it that run when the file is opened to process the data that was
written into it. The file has a digital signature on it also.

We are seeing an issue that we haven't seen before when doing this - if
the user has the excel file open, and does a Save As, we get the following
message:

"You have modified a signed project. You do not have the correct key to
sign this project. The signature will be discarded"

We haven't touched the macros, and haven't even opened up the VBA editor.
We can now reproduce this with Excel 2000, 2002, and 2003.

Does anyone know what could be causing this issue?

According to all the documentation I have read, if you do not modify the macros, you should be able to save the excel file with the digital signature intact.

In fact, we have previously done this and had no issues with it. I'm not sure why its happening now. Maybe something is corrupt in our original template - I'll have to look into that.
