SSL (Secure Sockets Layer) is a secure settlement developed for information securely over the Internet. It is a protocol that allows traffic between a web server and client (ie, the browser) to be strongly encrypted, using public-key technology. Many websites use SSL for secure areas of their sites, such as user account pages and online checkout.SSL secures billions of people’s information and data on the internet every day.

Especially, during online transactions or when transmitting data. Internet users have come to evaluate their online security with the lock icon that comes with an SSL secured website.

How do SSL (Secure Sockets Layer) Certificates work?

A browser or server tries to connect to a website (i.e. a web server) secured with SSL. The browser/server inquiry that the webserver identifies itself. The web server consigns the browser/server a copy of its SSL certificate.

The browser/server checks to see whether or not it trusts the SSL certificate. If so, it sends a message to the webserver. The web server takes back a digitally signed acknowledgment to start an SSL encrypted session. Encrypted data participates between the browser/server and the webserver.

Importance of SSL

The major purpose of an SSL(Secure Sockets Layer) certificate is to code information so that it can only be understood by the parties. Information given on Internet forms often passes through more than one computer before reaching its final destination, and the more “stops” it has to make, the higher the chance that a third party could gain access. An SSL certificate inserts random characters into the original information, rendering it incoherent to anyone without the proper encryption key. If the information does somehow wind up in the wrong hands, it will be unreadable and therefore worthless.

Customers visiting your site will know that you have coded in place in several ways. The most recognizable is the replacement of the “HTTP” protocol with “HTTPS“. This shows that a page is secure and is backed up by another visual cue: a lock image somewhere in the browser’s status or location bar. Today’s savvy online shoppers know to look for these things before making any online purchases and trust me, the stats show us that not having it can be sinister.

Types of SSL

  1. Extended Validation(EV SSL): In an  EV SSL, the Certificate Authority (CA) tabs the right of the applicant to use a specific domain name plus, it conducts a through an organization. The process of EV SSL Certificates is strictly explained in the EV tutorial, as formally formalized by the CA/Browser seminar in 2007.
  2. Organization Validated(OV SSL): The CA checks the right of the applicant to use a special domain name PLUS it controls some vetting of the organization. Additional vetted company information is displayed to visitors when clicking on the Secure Site Seal, giving enhanced visibility in who is behind the site and associated enhanced trust. The organization name also appears in the certificate on the ON field.
  3. Domain Validated (DV SSL): The CA checks the right of the applicant to use a specific domain name. No company identifies information is vetted and no information is showed other than encryption information within the Secure Site Seal. While you can be sure that your information is encrypted, you cannot be sure who is truly at receiving end of that information. DV SSL Certificates are fully supported and share the same browser recognition with OV SSL, but come with the benefits of being issued almost immediately and without the need to submit company paperwork. This makes DV SSL ideal for businesses that needs a low-cost SSL fastly and without the pressure of submitting company documents.
