加密

新建個(gè)測(cè)試方法，加密下得到密文跟公鑰。

import com.alibaba.druid.filter.config.ConfigTools;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import java.util.List;
import java.util.Map;

@RunWith(SpringRunner.class)
@SpringBootTest
public class DruidTest {

    @Test
    public void encrypt() throws Exception {
        //密碼明文
        String password = "123456";
        System.out.println("明文密碼: " + password);
        String[] keyPair = ConfigTools.genKeyPair(512);
        //私鑰
        String privatekey = keyPair[0];
        //公鑰
        String publickey = keyPair[1];

        //用私鑰加密后的密文
        password = ConfigTools.encrypt(privatekey, password);

        System.out.println("privatekey:" + privatekey);
        System.out.println("publickey:" + publickey);
        System.out.println("password:" + password);
        //用公鑰解密
        String decryptPassword = ConfigTools.decrypt(publickey, password);
        System.out.println("decryptPassword:" + decryptPassword);
    }

}

得到私鑰（privatekey ）、公鑰（publickey ）、加密后的密碼（password）如下：

明文密碼: 123456
