Hi all,
When we run a script tool, the geoprocessing result appears in the Results window, wherein we can re-run the result, publish a geoprocessing service, etc. This means that ArcMap is writing the signature (parameters and environment settings) for the tool run to disk, so it can re-run the tool whenever required.

My questions are these:
- Where does ArcMap write the files with this information?
- If it writes this information to disk, is it written as a binary file, or is it protected? (This is essential because, I'm passing some sensitive information as parameters to a custom script tool I've developed.)
Thanks and Regards,
Lakshmi Kanthan Muralikrishnan.
