File Lock is a nice encryption service that runs purely on HTML5. You do not need to install any kind of browser plugin or add-on for using this service. File Lock claims that it users AES-256 encryption to encrypt your files. The longer password you will choose, better it will perform.

It uses two ways in browser to perform encryption. One is HTML5’s FileReader way and other is Adobe Flash Player way. If you have browser that does not support any of the two things, you will not be able to use this application to encrypt your file.
This is really a simple but nice application to protect your files. As it works on Browser, it has file size limitations. I recommend to check this application with less important data. Few users also pointed out that File Lock lacks contact info which makes it suspicious.
