Introduction

If you have files that contain sensitive data on your computer, it may not be enough to have them sitting in a folder that anyone who sits down at your Linux Ubuntu computer would have access to. You can install and use the Cryptkeeper application to encrypt and password-protect your sensitive folders to keep both hackers and unwanted visitors who sit down to your computer from seeing that data. You can install Cryptkeeper on your Linux Ubuntu system through the Terminal application, and then use the Cryptkeeper interface to set up encrypted folders.

The Cryptkeeper application is a great option for encrypting folders you don't want other people to have access to.
