Re: Verifying Digital Signatures - Different results on different

The self-signed certificate is ok.
There is definitely something wrong with the digital signature itself (as
verified on XP pro sp2 with all security updates).
Would be interesting to get details of what systems VERIFY the signature as
valid.
Not sure why the signature is invalid though. Will poke around as time
permits.

Mitch,

I did hear back from the customer and the details that are shown for the
good case and the bad case are identical.

I also uploaded a test executable, in tabeware.zip, to ftp.ecrane.com (but
forgot to give the username and password, which are both 'ecrane').

Regards,

Phil

Can you see if there is more information available in the Details pane?
Usually there will be more information on why the digital signature is
not
valid (like unknown or untrusted issuer or something similar).
If you can sign some simple exe with the same certificate/key and point
me
to it, I can look at see what the problem might be.

This is being reported by a customer of ours, so I may not have the
complete
information.

The error message is shown in the Digital Signature Details window and
reads
"This digital signature is not valid". What other information could I
get
that would help.

The signer's cert is issued by Verisign.

The failures occur on most XP systems. The Vista machines accept the
signature.

Phil

Is the reason for "invalid" shown?
Is the signer's cert issued by a known CA?
What OS ?

I have signed an executable with SignTool. On some PC's the
Signature
(as
shown by Explorer) is shown as valid, on others it's shown as
invalid.

What could account for this?

Phil
