I've written file encryption utility; I know there are a bunch out there but I wanted one that was really easy to use for quick encryption/decryption. I'd never knock TrueCrypt; this is for use outside of TC. It also offers stronger encryption than any of the encryption tools of its type that I've tested. I want to make sure its very easy to use, so I want to add Nautilus context menu support for files and directories. There's plenty of how-tos using point and click, but obviously I need to do this with a script or using an API. Can anyone point to the right reference?
