What's new in Data Keeper
Version 1.0.5: Data Keeper is now more paranoid. It locks keys into physical ram (can't be swapped to disk) and wipes key and document memory as often as possible. An option to clear the clipboard when quitting was added. There are minor speedups when saving or unlocking documents.
