程式碼如下：

package com.example.demo.test;

import com.alibaba.druid.filter.config.ConfigTools;
import com.alibaba.druid.util.DruidPasswordCallback;

/**
 * 資料庫密碼解密
 */
public class DruidPasswordUtil extends DruidPasswordCallback {

    public static void main(String[] args) throws Exception{
 

        //密碼明文
        String password = "123456";
        //獲取公私鑰
        String [] keyPair = ConfigTools.genKeyPair(512);
        String privateKey = keyPair[0];
        String publicKey = keyPair[1];

        System.out.println("privateKey:"+privateKey);
        System.out.println
 
("publicKey:"+publicKey);
        //用私鑰加密後的密文
        password = ConfigTools.encrypt(privateKey, password);
        System.out.println("私鑰加密後===:"+password);
        //用公鑰加密後的密文
        String decryptPassword=ConfigTools.decrypt(publicKey, password);
        System.out.println("公鑰解密後===："
 
+decryptPassword);
        

    }


}

執行結果：
