With the explosively growing internet that has been merging with our lives for the past few decades, data and network security has been of utmost importance as society moves towards the age of digital information. As the number of users connected to the web increases, the threat faced by the network because of attackers also increases. Cryptography, the science of information security derived from the inherent needs of humans to converse and share information or communicate selectively at times, has the primary function of sending correct data over the network without any undesirable modifications. In cryptography, the original message is masked or encrypted by the sender and has to be decoded or decrypted by the receiver using a predefined set of algorithms decided before the commencement of the data transmission. Thereby, successfully avoiding redundant people from accessing or understanding the message as it is converted to content unreadable by the human eye.
