What is an SSL Certificate?

 

Digital certificates serve as the backbone of internet security.

Secure Sockets Layer (SSL) certificates, sometimes called digital certificates, are used to establish an encrypted connection between a browser or user's computer and a server or website. The SSL connection protects sensitive data, such as credit card information, exchanged during each visit, which is called a session, from being intercepted from non-authorized parties.

Creating a Secure Connection

 

SSL is the standard security technology for establishing an encrypted

Here’s how it works.

Invisible to the end-user, a process called the “SSL handshake” creates a secure connection between a web server and a browser. Three keys are used to create a symmetric session key, which is then used to encrypt all in-transit data.

  1. Server sends a copy of its asymmetric public key to browser.
  2. Browser creates a symmetric session key and encrypts it with the server’s assymmetric public key then sends it to the server.
  3. Server decrypts the encrypted session key using its asymmetric private key to get the symmetric session key.
  4. Server and browser now encrypt and decrypt all transmitted data with the symmetric session key. This allows for a secure channel because only the browser and the server know the symmetric session key, and the session key is only used for that specific session. If the browser was to connect to the same server the next day, a new session key would be created.

Why You Should Use a Digital Certificate

 

Establish trust and online security for your website visitors and business.

* Encrypt sensitive data

* Activate HTTPS and the lock icon

* Comply with PCI standards

* Prove legitimacy

* Strengthen brand identity

* Increase SEO rank

Take Security Further with Extended Validation

 

Extended Validation requires businesses to go through a rigorous validation process to prove identity, making it the highest degree of authentication available. EV-secured sites are given a green branded address bar, which is one of the most highly recognizable trust indicators on the web.
