# SM3散列算法 C库

国密SM3散列算法C实现

## 一次性计算

    void sm3_once_calcu(unsigned char *m, size_t bytes_length, unsigned char digest[32]);

## 可追加计算

    sm3_t hash_body;
    void sm3_init(sm3_t *hash_body);
    void sm3_update(sm3_t *hash_body, unsigned char *m, size_t bytes_length);
    void sm3_digest(sm3_t *hash_body, unsigned char digest[32]);

## 辅助函数

    void sm3_hexdigest(unsigned char digest[32], char hexdigest[64]);
