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. WebbThis means that CBC cannot be implemented this way, but faster parallelizable modes like CTR, GCM, and OCB are fine. This code example only implements the block encryption function ...
