Description

technical field [0001] The invention belongs to the technical field of block chain encryption, and in particular relates to a block chain national secret adaptation method, a national secret adapter, a system and a device. Background technique [0002] At present, mainstream blockchain companies try to apply national secrets to the blockchain, mainly focusing on: (1) replacing SHA-256 with SM3 as the default cryptographic hash algorithm; (2) replacing the elliptic curve signature algorithm with SM2 as Asymmetric encryption algorithm; (3) Replace RSA and elliptic curve algorithm certificates with SM2 certificates. For upper-layer protocols such as SSL, less is involved, and blockchain-related hardware facilities, such as hardware wallets, are rarely designed using national secret standards. In addition, because there is no specific standard for the national secret algorithm, it is difficult to apply national secrets to various cryptographic algorithms in the blockchain, that...
