Research on Encryption Algorithm Based on Python

With the rise of Python language in these years, more and more developers start to use Python language to do researches. Python language has its own advantage on Encryption algorithm. This paper discusses the principles of Caesar Cipher, Simple Substitution Cipher and Vigenere Cipher and their operating process based on Python, then concludes the characteristics and disadvantages of these Encryption algorithms from security and efficiency. It points out their applicable range, and in the end, forecasts the future of the Encryption algorithm based on Python.
