#263 closed defect (fixed)

Do not create thumbnail for encrypted PDF

Reported by: Lewis Rosenthal Owned by: Gregg Young
Priority: major Milestone: 1.4.0
Component: Lucide Core Version: 1.3
Keywords: Cc:

Description

We should not create thumbnails for password-protected (encrypted) documents, as this is a potential security risk (thumbnail could be viewed by anything, unencrypted).

Alternatively, encrypt the thumbnail data somehow, so that it may only be decrypted with the original password for the document itself.

Matthias, any more thoughts on this one? The last test you sent me was still creating these, and these thumbnails are viewable outside of the program and from the FOC within Lucide, as well, before the password dialog is raised.

Really? The build I have (RC2a) just created a thumbnail for a password-protected PDF.
