In this article we will discuss about security of your data on Internet. We will discuss about the technology, which is used for secure transaction on the Internet, a technology that ensures the cardholders that their information is safe during ordering process.
In order to create an SSL connection a web server requires an SSL certificate. When you choose to activate SSL on your web server you will be prompted to complete a number of questions about the identity of your website and your company. Your web server then creates two cryptographic keys-a Private Key and a Public Key.
In order to convert cyber text into plain text (readable format) or in other words if anybody wants to decrypt the message, has to posses a secret key. Encrypted message can sometimes be broken by cryptanalysis, also called code breaking.
Public key is known to everyone its not secret it is placed into a Certificate Signing Request (CSR). A certificate serves as an electronic “passport” that establishes an online entity’s credentials when doing business on the web. When Internet user sends confidential information to a web server, the user’s browser will access the server’s digital certificate and establishes a secure connection. In computer language certificate is a data file containing your details like your name, certificate serial number and expiration date, copy of certificate holder’s public key and the digital signature of the certificate-issuing authority.
Suppose you are a customer and you want to send confidential information to a secure site. Then how everything will work As the customer you won’t see all the process which take place behind the scenes so that you will experience uninterrupted shopping experience, you will only see a “padlock” icon in the browser’s status bar and the “https://” prefix in the URL.
This process is known as “handshake” process.
Now suppose if a customer attempts to submit personal information to an unsecured Web Site, the browser’s security mechanism will show a warning telling the customer that this site is not a secure site, accordingly customer can switch over to some other secure sites.
