Quick and dirty Python script to Base64 decode a text file with GUI

This Python script allows a user to decode a Base64 string that is saved in a text file. This script utilizes TKinter, the premier choice for Graphical User Interface (GUI), to select a file, then decode the contents of the file into the console. This script is compatible with Windows, MacOS, and Linux hosts.
