WebbThe SM4 algorithm requires the message to be of any length that is a multiple of 16. By default, the length of the message to encrypt / decrypt is assured by users. You may choose to turn on PKCS5 Padding Mode(by passing the argument padding with a TRUTHY value), telling Python to do the padding before encryption for you. Webb12 sep. 2024 · SM4 is a symmetric encryption algorithm, specifically a blockcipher, designed for data encryption. 1.1. Purpose This document does not aim to introduce a new algorithm, but to provide a clear and open description of the SM4 algorithm in English, and also to serve as a stable reference for IETF documents that utilize this algorithm.
