What is SSL?

Quick answer: What is SSL/TLS? It is the encryption behind https that protects data sent between your website and visitors, shows the padlock in browsers and is expected by search engines.

SSL is the acronym of Secure Socket Layer (SSL) and TLS is the acronym for Transport Layer Security. SSL/TLS is a web protocol for getting information transferred between a client’s browser and the site they are visiting.⁣ SSL is depreciated in the year 1999 post the release of TLS 1.0, it is common to denote these protocols as SSL even these days. The most recent version of TLS is TLS 1.3 released in August 2018.

SSL/TLS works by binding the websites and organizations to cryptographic key-value pair by means of digital records known as X.509 certificates. Each key pair comprises a private key and a public key. The private key is kept safe, and the public key can be generally conveyed through an endorsement.

If the website has a valid SSL/TLS it is indicated with the padlock symbol in green or grey colour along with the details based on the SSL/TLS certificate and plans. If the website does not have an SSL/TLS installed it will be denoted as crossed padlock in modern web browsers. Furthermore, a modern web browser also prompts the user that the website is not secure.

SSL and No SSL Difference

Why SSL/TLS is important?

SSL/TLS converts HTTP:// to HTTPS:// . SSL/TLS provides encryption for our website. Following are the main advantages of having SSL/TLS for your website.

  • 1. Credibility: The server introducing the endorsement is in control of the private key that coordinates with the public key in the certificate.
  • 2. Trustworthiness: Documents endorsed by the certificate (for example web pages) has not been adjusted on the way by a man in the middle.
  • 3. Encryption: Interchanges between the client and the server are encrypted.
  • 4. Google considers SSL: HTTPS has been an affirmed Google ranking element since 2014, so getting the help of a little ranking boost is a valid justification for getting SSL
