Implementation Analysis of Encryption and Decryption Algorithm Based on python Language

Facing the Internet information transmission of WAN or LAN, it is difficult to ensure the security and stability of data transmission after key encryption by using traditional one-way password encryption and two-way stream password encryption. Therefore, a hybrid encryption algorithm of RSA, DES and BASE64 developed based on python language is proposed, and the encryption and decryption scheme of information transmission between network client and client, client and server is set up, including the encryption and decryption implementation of digital certificate accuracy, server registration, user login and communication, file transmission, password modification and log processing, etc., to improve the encryption and decryption security level of data file transmission and log processing, and to maximize the protection of network instant messaging Security and stability.
