Sm3 encryption
Webb29 dec. 2024 · SM3 is a hashing algorithm SM4 is a set of encryption/decryption block-cipher algorithms As a lot of the SM2, SM3, and SM4 documentation and code usage is … WebbThese functions implement encryption and decryption of data with AES (Advanced Encryption Standard) algorithm. Key length depends on encryption mode. It is 16, 24, and 32 bytes long for -128-, -196-, and -256- modes respectively. Initialization vector length is always 16 bytes (bytes in excess of 16 are ignored).
