An SSL Certificate is an essential component of the data encryption process that makes internet transactions secure.We consider them as digital passports that provide authentication to protect the confidentiality and integrity of website communication with browsers. SSL is the original name of the cryptographic protocol for authenticating and encrypting communications over a network. SSL uses port number 443.
How it work?
The primary purpose of SSL is to provide a two-way secure transport connection-layer connection between server and client two endpoints. The web server sends the browser/server a copy of its SSL certificate.
The connection is typically between a Web server and a client’s browser and a mail server and the client’s email application.
Types of SSL/TLS Certificates
Extended Validation (EV) Certificates
Most online users prefer EV certificates because they come with the most comprehensive verification checks, which include domain verification as well as crosschecks that tie the entity to a specific physical location. This type of verification leaves a detailed paper trail, providing customers with recourse should fraud take place while transacting on that website. EV certificates are distinguished by a locked padlock, organisation name, and sometimes the country ID in the web address bar in most major browsers.
Organization Validated (OV) Certificates
OV certificates, in addition to domain ownership, the organisation is validated and the certificate details can be viewed on most major web browsers, giving online users the opportunity to determine if the site they’re on is legitimate.
Domain Validated (DV) Certificates
A website secured with a DV certificate offers only a locked padlock in the address bar but does not show organisation details because they do not exist. These certificates validate domain ownership only, can be acquired anonymously, and do not tie a domain to a person, place or entity. For this reason, many websites using DV certificates are linked to fraudulent activity.
