Illustration of Viewing Encrypted Documents
When creating a new document and saving that document with a password (encrypted), the contents are viewable from the LibreOffice launcher. Images can be seen, along with text if the text is large enough.
Attached is an image illustrating the issue. As you can see, the launcher is asking for a password to open the file, but all the of the contents of the first page can be seen.
Thanks, already reported as Bug 80755 - StartCenter displays thumbnails of password-protected files.
