Webb2 dec. 2024 · SM4 is often used for data transmission encryption of government systems. For example, this algorithm can be used when we transmit parameters from the front end to the background. Encrypt the parameter data, then decrypt the encrypted data in the background and store it in the database to ensure that the data will not be leaked during … WebbSM4 is a symmetric encryption algorithm, specifically a blockcipher, designed for data encryption. 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.

The normal way to use a block cipher to encrypt/decrypt a plaintext of arbitrary length is to pad it to a whole number of blocks with a known padding method - for example, PKCS7 - and then use a block chaining method to encrypt the sequence of blocks. When you decrypt, the padding tells you how many bytes to remove to recover the … Webb6 juli 2024 · implement the compact circuit of SM4.
