Well, it worked at some point. For years I kept some of my sensitive stuff on a single EN note, about 50 lines long, encrypted as a single note. I added and modified as needed. Last week I went to add a line and it would let me decrypt it, but not encrypt it back again unless I did it in separate notes, sometimes allowing me 8 lines, other times 15 or 20. Very frustrating. Should I be looking at OneNote?
I don't understand the reference to "greatest encryption tool under the sun". I'm not trying to stump the NSA, just keep it away from thieves.
