Have you ever wondered why a lock sign appears on some web pages? Also if you pay more attention to the URL (Uniform Resource Locator) of a website, you might have come across an extra “s” after the “http”. So, for instance, you see https://www.mfidie.com instead of the normal https://www.mfidie.com. This is widely and mostly seen on sites that require sensitive information from its users.

What does the “s” represent? How does it work? How do you get it on your webpage?

Worry no more. This short write up seeks to answer the questions above. Without halting my typing let’s get into it.

The additional “s” simply means that the website is secured and any data that is passed on it is encrypted on the web from the server side. An unsecured webpage is equivalent to non-encrypted data or plain-text sent back and forth. Plain-text data opens up for interceptions, eavesdropping and even stealing from unauthorized persons. The technology that powers this is called SSL, which stands for Secure Sockets Layer.

This link ensures that all data passing through is private and remains private. This is done in that websites which has obtained an SSL certificate from reseller (i.e. ClickSSL) of trusted Certified Authorities or directly from CA (Certificate Authority). Browsers, Operating Systems and Mobile Devices also maintain a list of CA (Certified Authority) root certificates.
