The primary goal of this project is to understand how Caesar cipher works. Here, we are using the python programming language to implement the Caesar cipher algorithm. It is not mandatory to know python in order to run the program. The main focus is to understand how the input message is converted into ciphertext with the help of encryption logic and then use a similar pattern to perform decryption. You will be provided with a python code that has implemented encryption logic. Your task is to understand the logic and implement decryption by simply writing the logic explained in the pdf file.
