Validating a web page requires 3 components.
the Codel Document Protection Software
The Codel online database and, of course
The page itself.
The process is fairly simple. Assuming you've downloaded and installed the relevant software, the steps are these:
Somewhere on the page - if it is Codel protected - it will
show the 
logo. Throughout our own site, for example, the logo is in the bottom
right corner of every page.
Click on it. It brings you to this page. This is only so that you can read these simple instructions. In future, once you have loaded the software, you will simply follow its instructions. The real purpose of the logo is simply to let you know that the page authors are claiming an entry has been made on the Codel database in respect of that page. This is so you can verify for yourself that it has not been tampered with in any way since it was registered.
The software will prompt you for the url of the web page. You can cut and paste this from the address bar of your browser or simply click the button "Current Web Page" and the software will attempt to read the url using the Windows API.
The software will then download the page and compute its hash. It submits the hash to Codel and Codel confirms or denies that the hash is contained in its database. If it is present in the database and old enough to be protected by Codel's Protected Audit Trail, (usually any entry over 24 hours old is fully protected) then you can be certain that the page is as it was at the time it was first registered with Codel. No more and no less than that.
We make no claims in regard to the content of the web pages we validate other than they have or have not been changed in any way. Whether the content is correct, safe, valid or meaningful is still for the reader to judge for themselves.
