Everyone has private data, and if your data need protecting, then Kryptel is what you are after. Kryptel is an easy-to-use no-hassle solution even a new computer user will be comfortable with. You want to encrypt a file? Just drag it to the Kryptel icon, and Kryptel will do the rest.
if the user should want to add one when encrypting, to allow recovery... when he forgot the password.
(but allow users to insert their own hint question)
