SSL – Secure Sockets Layer,an encryption technology created by Netscape. SSL creates encrypted connection between Web Server and Visitor’s Web Browser allowing Private Information to be transmitted without the problems of data tampering or message forgery. It is designed to enable applications transmit information back and forth securely.
SSL Certificates are small data file that digitally bind a cryptographic key to an organization’s details. When installed on a web server, it activates the padlock, https (over port 443) and allows secure connections from a web server to a browser. Typically SSL is used to secure credit card transactions, data transfer, logins and more recently is becoming the norm when securing browsing of social media sites.
SSL Certificate makes the use of Certificate Authority (CA) as a third party in order to identify both ends of the transactions which clearly happen when one browse the internet, hence opening a web page, an SSL Certificate enables encryption to protect online transaction. This encryption is actually responsible for securing the private data whenever online private transactions are made and this way it protects data from linking to other users or sources on web. SSL Certificate is unique to each other in order to identify the user. At last, the CA will authenticate the identity of the certificate owner before passing out any information.
How SSL Certificate Work? Below is the procedure:
1) When any user browses the internet, immediately the browser requests for a secure page which starts with https:// , letters before domain name sayhttp://something.com/with SSL it will be browsed as : https://something.com
2) Using certificate, web server sends the Public Key with the certificate.
3) Browser then verifies whether the issued certificate is from trusted party or not and also makes sure that it is valid or not expired.
4) Using Private Key, the web server decrypts the encryption key, the URL, and the http data.
5) Later web server sends back the requested data.
6) Then the browser decrypts the http data and displaying complete web page information on the computer screen.
Secure Web Site Connection:
SSL Certificate plays an important role in connecting to a Secure Web Site. Below are the advantages:
Online Secured Messaging: takes place through encryption. Web Server works with SSL Certificate in order to create encrypted channel uniquely. Basically, channel consists of Private Key and Public Key to protect the information or Private Data from other users.
Online Credentials for Established Identity: SSL Certificate allows highly secured browsing of online credentials which basically contains the identity of a person for instance, driver’s license, passport and company badge.
Generating Trustworthy Credentials: While Certificates pass through lot of authentication, credentials are rest assured to be reliable and strict. For instance, VeriSign is one of the leading certificate authorities for its punctilious identification methods.
Complete Protection on HTTPS: Basically, SSL Certificate secures https data. Such tight security allows one to achieve the success of online business.
Need of SSL Certificate:
Anyone transmitting sensitive information through web site, such as personal information as credit card details, need to secure those with SSL encryption. Unless it is secured by SSL Certificate, it is possible that every piece of data could be seen by others. Customers won’t trust the web site without an SSL Certificate. On research it is found that about 60 / 65 percent of online shoppers have terminated the online order due to lack of “trust” during transaction. In short, “SSL Certificate is necessary to gain customers trust”.
