With the wide use of the Internet, virtually everyone is now connected to each other through their computers. This has led to a positive impact in the human environment socially, economically and in their day-to-day transactions. There is, however, a major hindrance in trying to establish an effective and safe communication line: an outside user, not intended to be a part of the connection, might try to steal the information being passed to a legitimate user. This being a security issue, information security therefore plays a vital role in internet transactions. It can be deduced that secure digital communication is necessary for many aspects relating to web based activities, e-commerce, and secured instant messaging.
