[OCLUG-Tech] locked pdf display
			
I've made a few charitable donations and got e-receipts as pdf files. 
Some of these are "locked". They open in Acrobat reader (I've got it 
installed on my Eee 900), but the document reader (evince) asks for a 
password.
Clearly, I've no immediate "need", but am curious if there's an open 
source tool for viewing/printing such files.
