Excel 2002 Verisign Digital signature

G

Hello,
We want to purchase a digital signature, and attach it to some of our
Excel files for internal company use. The files will have an internal
macro that allow the user to send an email that contains as an
attachment the file.

I was wondering how this will work for us? If a user edits an excel
file, I read that it will invalidate the cert for the file. The file
may actually be used as a template. A user will enter data in the file
and submit it, and may need to do it again a month later. This would
be done company wide, and we're not using Sharepoint or Infopath.

Is it possible for the user retain their general security settings and
still use a trusted file like the one I described?

We have specific reason for this being done purely in Excel. When the
files are emailed back an addin is used to automatically populate the
data into a 3rd party product.

As a company Excel 2002 is being used.

Thanks in advance,

Gabe

As understand it, the certificate will only become invalid if the VBA code
is edited. As such, changes the Excel data part of the file will not affect
the certificate.
Also, if this is purely in-house, would a SelfCert.exe generated certificate
be sufficient, avoiding any cost.
