Ubuntu – How to encrypt individual folders

directoryencryptionpasswordSecurity

Let's say that I have a folder, within my Documents folder, that has files I want no one to access without a password.

Is there a way to lock down that folder so that it's password protected / encrypted?

In fact, is it possible to password-protect any individual folder?
