PalletOne has now implemented support for the SM2/3/4 national secret algorithm. The blockchain uses cryptographic algorithms to ensure that data is not tamperable, including digest generation, signature and verification of asymmetric keys, and private keys based on certificates. The SM2/3/4 password has high complexity, fast processing speed, lower machine performance consumption, better performance and security. The blockchain application using the national secret algorithm meets the domestic standards and regulatory requirements.

The SM2/3/4 algorithm is a safe and efficient elliptic curve public key cryptography algorithm independently designed and unique in China. It was released by the National Cryptography Administration on December 17, 2010 and incorporated into international standards.
