Text Encryption Using Advanced Encryption Standard (AES) Algorithm

Abstract

With the increasing importance of data security in the digital age, the need for robust encryption techniques has become paramount. The Advanced Encryption Standard (AES) is regarded as one of the safest encryption techniques currently in use. The AES encryption algorithm is a symmetric block cipher algorithm with a block/chunk size of 128 bits. These distinct blocks are converted using keys that are 128, 192, and 256 bits long. The ciphertext is created by joining these blocks together once they have been encrypted. The decryption is done in the reverse order. This study discusses the implementation of text encryption using the AES algorithm. The Graphical User Interface of the text encryption system was built using python library Tkinter while the encryption and decryption algorithm were programmed using python and its libraries. The tools used for the implementation were the text editor and python Integrated Development Environment (IDE).
