Website Use Security
HTTPS (Hyper Text Transfer Protocol Secure) is a secure version of the Hyper Text Transfer Protocol (http). Secure means of transferring data using the https protocol in the World Wide Web where secure ecommerce transactions, such as online banking transactions and other financial transactions are involved. In other words, https encrypts the session with a digital certificate i.e., HTTP over SSL (Secure Sockets Layer) which can be used by Web browsers and HTTPS - capable client programs. So if the website begins with https:// instead of http://, it is a secure site. The address bar in the browser will begin with https instead of http, if a web site is secured. Web browsers like IE, Internet Explorer etc., display a pad ”lock” icon to indicate the website is secure, which also displays https in the address bar. This padlock icon is displayed only when an SSL certificate is installed by their web server. If the padlock icon and the web link begin with https then it can be concluded that the site is legitimate and secure to provide confidential information or carry financial transactions. Hence the HTTPS Protocol work with the combination of programs including the browser programs which takes care of the encryption/decryption routines that exist on the web hosting servers. Most typically HTTP data is sent over TCP/IP port 80, whereas SSL HTTP data is sent over port 443.
How SSL Works?
SSL uses a cryptographic system that uses two keys to encrypt data, firstly a public key known to everyone and the second is the private key known only to the recipient. SSL an unique and effective way to achieve data and ecommerce security. So when a SSL - Digital Certificate is installed on a web site, a padlock icon can be seen at the bottom area of the navigator and also the address in the address bar will begin with "https" instead of http during a secure ecommerce transaction, which means that the data is encrypted.
