What Types of SSL Certificates can be used for Online Shopping Website

Website Security Certificates

Presently, the security of online internet transactions is very critical, in order to prevent the unauthorized usage of credit and debit card numbers and other internet frauds. In order to secure these transactions, a Secure Socket Layer, or SSL certificate is installed on an ecommerce website. Though some sites also operate without this certification, it is advisable to use the same so as to ensure maximum data security.

How an SSL certificate provides a sense of security?

Adding an SSL certificate gives customers a feeling of security through two different ways. Firstly, an https:// notification will certify that the site is secured. Along with this, the credit card numbers will appear encrypted and information on the website will be matched with the certificate authority. Digital certificate is mainly an electronic credit card to establish the online shopper's credentials of a website. The digital certificate must be used on the same domain name that has been stated in it; otherwise it will be termed unauthorised.

Types of SSL certificates

There are three types of certificates that can be used on an ecommerce website. Different levels of validation are given to a company in order to prove its genuineness.  The first one is Domain validated (DV) SSL certificate. Issuers of this certificate check the ownership credentials of a domain as against the WHOIS database. Only the applicant's name and contact information is verified in this type. It is the simplest form of SSL and prevents users from encountering warning screens. The next type is an Organizationally Validated (OV) security certificate. Rigorous certification is followed in this type by checking organisational credentials and verifying the activity of business and home addresses of entrepreneurs. It is much more advanced than DV SSL. Last is the Extended Validation (EV) SSL, also the newest form introduced as recently in 2007. It adheres to industry-recognized certification procedures and their validation criterion is even more stringent. One of the new features introduced in this is color coding of web browsers and denoting secure connections. Browser windows turn green on encountering a valid website and red for a phishing or fake website.

Importance of encryption for an ecommerce website
  
With the help of a website certificate, communication between email client and exchange server can be made more efficient. It must be noted that validity of businesses is certified by ensuring legitimacy. SSL can be said to be a type of website certificate as encryption is an important part of security on websites. It is essentially aimed at certifying that the user is legitimate.

How digital certificates work to make your website secure?

Digital certificates are a set of tools used for managing the authentication of different users visiting a particular website, where the identity details are recorded. Prior to the advent of digital certificates, in order to make a website accessible to a limited audience and authenticating incoming user traffic, the only way was to allot a unique username and password to the focused customers. Hence, the use of such digital certificates provided a more robust and efficient access control mechanism, along with many other merits over assigning username and password, whose misuse is a serious security loop hole.  

Introduction to an https certificate

At present, the entire information exchange and communications taking place on the internet are done on a standard protocol, called as the hyper text transfer protocol (http), which is one of the several types of digital certificates. The http protocol is functional at the highest layer of the Transmission Control Protocols and Internet Protocol (TCP/IP) model and is actually a language that defines a format, according to which various web servers and web browsers communicate with each other. The basic http digital certificate is a clear text protocol that manages and transfer data to-and-fro across a particular network, which unfavorably makes them vulnerable to exploitation from unrestricted access.

The lack of privacy in http certificates made way for the arrival of an https certificate, which is nothing but http secure. These types of digital certificates offer enhanced security over http certificates and are ideal for use in the exchange of highly sensitive information, such as online identities, usernames, passwords and debit or credit card numbers, along with confidential corporate business secrets. The fundamental idea behind an security certificate is that they use multiple encryption levels, so as to keep the information transfer as discreet and secure as possible.

In line with the various information encryption methods, the https certificate gives a definition to the use of encryption keys, so as to ensure a smooth and secure data flow between web servers and web browsers in the network. It must be noted that every web server has its own public encryption key that can be made accessible to a particular user, in order to establish a safe and secure web connection.

The digital certificates come into the picture when an end user's web browser wishes to verify if the public key offered by the web server actually belongs to any individual or organisation, which claims itself to be a genuine source. Further, the websites are deemed secure and genuine, when they display their digital certificate to the visiting user on his/her web browser. These kinds of certificates can be availed from a highly trusted third party, called Certificate Authority (CA). The CA issues a digital certificate that is usually enough for verifying that the website source and ownership is nothing but genuine.
