SSL Certificates

What is an SSL Certificate?

SSL Certificates are small data files that digitally bind a cryptographic key to an organization’s details. When installed on a web server, it activates the padlock and the https protocol and allows secure connections from a web server to a browser. Typically, SSL is used to secure credit card transactions, data transfer and logins, and more recently is becoming the norm when securing browsing of social media sites.

SSL Certificates bind together:

  • A domain name, server name or hostname.
  • An organizational identity (i.e. company name) and location.

An organization needs to install the SSL Certificate onto its web server to initiate a secure session with browsers. Once a secure connection is established, all web traffic between the web server and the web browser will be secure.

When a certificate is successfully installed on your server, the application protocol (also known as HTTP) will change to HTTPs, where the ‘S’ stands for ‘secure’. Depending on the type of certificate you purchase and what browser you are surfing the internet on, a browser will show a padlock or green bar in the browser when you visit a website that has an SSL Certificate installed.

Why is the Root Certificate important?

SSL Certificates need to be issued from a trusted Certificate Authority's Root Certificate, and preferably by a 2048 bit Certificate that's widely distributed. The Root Certificate must be present on the end user's machine in order for the Certificate to be trusted. If it is not trusted the browser will present untrusted error messages to the end user. In the case of e-commerce, such error messages result in immediate lack of confidence in the website and organizations risk losing confidence and business from the majority of consumers.

Companies like GlobalSign are known as trusted Certificate Authorities. This is because browser and operating system vendors such as Microsoft, Mozilla, Opera, Blackberry, Java, etc., trust that GlobalSign is a legitimate Certificate Authority and that it can be relied on to issue trustworthy SSL Certificates. The more applications, devices and browsers the Certificate Authority embeds its Root into, the better "recognition" the SSL Certificate can provide.

GlobalSign has, for over 15 years, been operating the GlobalSign Ready program for Root Certificate embedding. This program ensures its in-house engineers from America, Europe and Asia are in constant communication with the application, device and browser vendors to ensure the GlobalSign Root Certificate is present everywhere that may be used for SSL sessions.
