Secure sensitive information by encoding and decoding messages

The project aim to develop a secure sensitive information by encoding messages. Message encoding and decoding is the process to first convert the original text to the random and meaningless text called ciphertext. This process is called encoding. Decoding is the process to convert that ciphertext to the original text. This process is also called the Encryption, Decryption process. This objective of this project is to encode and decode messages using a common key. This project will be built using the Tkinter and base64 library .In this project, users have to enter the message to encode or decode. Users have to select the mode to choose the encoding and decoding process. The same key must be used to process the encoding and decoding for the same message. Base64 is a library that allows the user to encode and decode the string. The string to be encoded should be in byte form. A function to encode binary information to ASCII characters then decode those ASCII classic characters to binary data is provided by the base64 module of the standard GUI Python library, Tkinter. On the command prompt, we use the pip install command to install the library. In addition to base64, base 85 is also used to provide additional encoding. Base64 and Base84 are included in the newer versions of Python3, so be sure to check the version beforehand.
