APLIKASI PENYANDIAN PESAN TEKS BERBASIS WEB MENGGUNAKAN ALGORITMA BLOWFISH

Abstract

The Blowfish algorithm is one of the existing encoding systems. Encoding aims to make a message more secure for its confidentiality. The blowfish algorithm is one of the modern cryptographic algorithms that uses symmetric keys in the encryption and decryption process. The application of the blowfish algorithm in this study is to secure text messages between the sender and recipient of the text message through a web?based application. Cryptography is the art and science of protecting data transmission by converting it into a certain code and is only intended for people who only have a key to change the code back which functions to maintain the confidentiality of data or messages. Applications for sending
messages using the blowfish algorithm are made using the PHP programming language and MySQL database. This web?based text message encoding application consists of several menus, including login menus, lists, incoming messages and sending messages. The web?based text message encoding application runs well according to each existing menu.
