Frequently Asked Questions
Why use Chinese National Cryptography algorithms?
Chinese National Cryptography algorithms are Chinese commercial cryptography standards widely used in finance, government, defense and other fields. They have all passed evaluation and certification by the national cryptography management department, ensuring security.
What are the differences between SM2, SM3, and SM4?
SM2 is used for asymmetric encryption and digital signatures, SM3 is used for data hashing and integrity verification, and SM4 is used for symmetric encryption. The three are typically used together to implement a complete security solution.
