Hypertext
Transfer Protocol (http) is a standard universal set of rules for sending and
receiving content between client and server across the Internet network. We use
Http to access html pages, video, images and any other resources. There are
situation to access/upload the confidential information from a server, which
require secured connection between client and server in order to prevent avoid
data leak from unauthorized party.
Netscape
corporation comes with a solution to allow secured transaction via https
connections. The basic protocol for http is same as that of https mostly while
the differences in method occurs such as browser http
request uses default port 80 for setting connection with server while
https request uses 443 port for
connection. https request uses encrypted layer/method for transferring and receiving
information, so that information cannot be accessed by anyone else except
client and server.
Two
types of encryption layers are used for composing https requests.
1)Transport
Layer Security (TLS) and,
2)Secure
Sockets Layer (SSL)
Basic
flow start with server response while client establish https connection. Server
offers a menu of supported encryption methods. Client select one of this method
to set up connection. Then client and server exchange third party verified
certificate to prove their identities and unique key to start the
encrypted information flow and close the
connection.
Example
of certificates and https connection shown in the snap below,
When transferring sensitive information on internet, click at lock icon to the left of the site’s URL in the address bar to check the SSL info. SSL is a protocol that provides an encrypted tunnel between client and the website server to prevent third parties from disrupting the information traveling through the tunnel.
We use https in many places that involves user login/password protected web pages, mail account, payment gateways in ecommerce websites, social platform, banking, user filled forms and other applications that need security. Please give your feedback, how you like the post?
