Linux folk might like this, especially if they use dropbox: encrypt yo stuff with encfs! Then install gnone-encfs-manager to easily handle your stashes. This can let you set up a private folder and sync an encrypted version of it in your dropbox. That way, it's backed up AND encrypted, and all you ever deal with is the decrypted folder in your home directory.
Code:
sudo add-apt-repository ppa:gencfsm/ppa
sudo apt-get update
sudo apt-get install encfs gnome-encfs-manager
encfs ~/Dropbox/.encrypted ~/Private
Select 'p' unless you want some advanced stuff you can figure out. Set options in the manager such as changing your password, how to automount, and whether you want the password saved in your keyring or if you want to enter it in manually each time.
This makes it
very easy to handle a variety of encrypted stashes, whether locally or on a usb drive, say.
If you wonder why my interest, TrueCrypt has been discontinued. Some complain, but it makes sense because virtually every system has an encryption solution, often better solutions. Though, TrueCrypt offered something unique, I needed to find a native linux approach. This was it.
