Implement cryptographic algorithms, SM2, SM3, SM4, you can test the correctness of the algorithm on the interface, and includes key public key algorithm specification
SM2 elliptic curve public-key algorithm
SM3 password hash algorithm
Applies to commercial password in the application of digital signatures and authentication, message authentication code generation and validation, as well as random number generation can meet a variety of password security requirements of the application.
SMS4 cipher algorithm
The grouping algorithm is 128 bits in length, a 128-bit key length. The encryption algorithm and key expansion algorithm using 32 rounds of nonlinear iteration structures. Decryption and encryption algorithm is identical to that of the only round key using the reverse order of decryption wheels key is encrypted and the key reverse.
