Abstract

Information security in the world at large has been very crucial as it helps organizations, individuals, and groups to secure files, data, programs. Data are compromised at a high rate as there is a significant increase in the number of hackers, intruders, or attackers. Hacking information aims to attack confidentiality, integrity, and availability of the message. The Pythagorean triple-based method makes use of the new Pythagorean triple algorithm in which p>q, one of them is odd and the other even. A "Pythagorean Triple" is a set of positive integers, a, b, and c that fits the rule of a2 + b2 = c2 where c represents the length of the hypotenuse; a and b represent the length of the other two sides of a right-angle triangle. a2 + b2 = c.2 The paper implementations make use of secret key P and Q as a solution to the Pythagorean triple algorithm. JavaScript, HTML, and CSS are the programming language chosen to perform the encryption and decryption of messages. JavaScript enables interactive web pages and is an essential part of web applications. The majority of websites use it, and major web browsers have a dedicated JavaScript engine to execute it. A Pythagorean triple-based cryptographic system is a secured cryptography system that prevents cryptanalytic and brute-force attacks to a large extent.
