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 widely recognized as one of the most secure encryption algorithms available today. This abstract outlines the implementation of text encryption using the AES algorithm in Python, providing a comprehensive overview of the process and its practical applications. 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. Once it encrypts these blocks, it joins them together to form the ciphertext. The decryption is done in the reverse order. 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.
