How to add digital signature timestamp to file tooltips

Post by *misvin »

If you place the mouse above a filename for about half a second, a small window is shown with comments from Explorer (file tooltip).

Configuration => Display => Help texts => Comments from Explorer (OLE2).

TC allows to add user-defined values to the file tooltip.

My question: how to add digital signature timestamp to file tooltips (in case of *.exe and *.msi files)?

For example, the file tcmd912x32.exe has a digital signature timestamp "24.12.2017 12:20:31" (see tcmd912x32.exe Properties => Digital Signature Tab => Signature list).

Currently there is no content plugin to get this. If you have a column in Explorer, e.g. via an Explorer extension, you could use the Shelldetails plugin.

Otherwise someone would have to write a content plugin. Getting the timestamp is actually quite complex, but there is sample source code from Microsoft it anyone wants to write a plugin:

Have a look at the GetTimeStampSignerInfo function.
