Probably used by ExtMgr and TER somehow. allows you to see if a hacker
has tampered your extension...

Why not? I have to modify some of them locally...

You can ignore it completely or update it. If you want to update, click
on the extension name in the extension list, ExtMgr will show
information about the extension. Select "backup/delete" in the combo box
on the top of the page. Click a link named "Update extension EM_CONF
file". This will update MD5 checksum.
