“First off, I’ve enjoyed the numerous tips and tricks posted by the knowledgeable folks at OS X Daily. I have something I think you guys might be able to help me with. Recently I found myself writing a journal, and as such I really want to find a way to password protect it so my inner thoughts don’t end up in the hands of the wrong person. Multiple people use my laptop and its not a good feeling knowing that anyone could just double click my text file of emotion and find out everything about me! All I’m looking for is a way to encrypt a file on a file-by-file basis, do you guys have any suggestions?”
