Adding Time Stamps to Previously Signed Files
Time stamps are normally included when a file is signed using SignTool with the -t
option. In addition, time stamps can be added to files that were signed without a time stamp. The following command adds a time stamp to a previously signed file:
signtool timestamp -t https://timestamp.digicert.com MyControl.exe
Note
The file to be time stamped must have previously been signed.
