Implementasi Kriptografi Untuk Keamanan Pesan Chatting Menggunakan Algoritma Pontifex

Abstract

Data is a collection of important elements that are useful, such as images, sounds, text. Data is a component that is vulnerable to theft or wiretapping, especially if the data contains important and confidential matters. Many people who have an interest want to get data illegally without going through official procedures. Pin, Password, Account Number, or Credit Card Number are small pieces of data that are often misused by irresponsible individuals. This of course needs to be prevented so that incidents of data theft do not occur repeatedly. To facilitate the process of securing text so that it is not easily read by others so that the authenticity of the data is maintained. To protect information from those who are not entitled to access, an algorithm is used, namely the Pontifex algorithm in maintaining the confidentiality of the text message. Many data security techniques have been developed at this time, this certainly makes it easier for all parties to secure data. One that is widely used today is a computerized security system that can be used anytime and anywhere. This research uses Visual Basic 2008 tools in the process of safeguarding information from other parties who are not entitled to access it.
