Chinese cryptographic algorithms are Chinese algorithms issued by the State Cryptography Administration Office of Security Commercial Code Administration (OSCCA). Common algorithms include SM1, SM2, SM3, and SM4. The key length and block length are both 128 bits. To meet bank customers’ requirements for database security capabilities, openGauss 2.0.0 and later versions support Chinese cryptographic algorithms to enhance enterprise-level security capabilities of databases and improve product security competitiveness, including the SM3 algorithm for user authentication, and the SM4 algorithm for data encryption and decryption.
