Locked 2 offers a really simple but elegant computer locker, which will lock up your computer until you type the password. It is a great locker.

HTML Lockdown uses strong encryption algorithms to protect your page content and further ensures the safety of that content by requiring you to select a password.
Using these methods, the program will prevent anyone from viewing your source code or stealing your art work.
However, all of your encrypted pages will have the exact same appearance as the original pages and can be viewed in all modern web browsers.
You see, HTML Lockdown modifies the source code of a web page making it unreadable and non-editable without changing the way a page looks in a browser.
Here is even more of what HTML Lockdown does:
Protects your PayPal links
Hides your original HTML source code
Prevents your images from being copied and used by someone else
Creates special password-protected pages
Stops right-clicking
Stops offline browsing
Stops URLs from being displayed in the browser bar
Works with any web host
