Druid密码加解密

数据库密码加密：

1. maven引入druid jar包

   <dependency>
       <groupId>com.alibaba</groupId>
       <artifactId>druid</artifactId>
       <version>1.0.26</version>
   </dependency>

    

2. 在本地找到jar包所处目录，如：
   
    
3. 打开cmd，定位到所在目录，执行指令：java -cp druid-1.0.26.jar com.alibaba.druid.filter.config.ConfigTools 你的密码（示例为123456）：

   D:\>cd D:\Maven Repository\com\alibaba\druid\1.0.26
   
   D:\Maven Repository\com\alibaba\druid\1.0.26>java -cp druid-1.0.26.jar com.alibaba.druid.filter.config.ConfigTools 123456

4. 此时获取到公钥publicKey，私钥privateKey，以及密码password，将加密的password填入publicKey分别填入druid的配置中

 

数据库密码解密：

1. 建立一个DesPassword类写main方法，继承druid中的DruidPasswordCallback类。
2. 在main方法中引用ConfigTools.decrypt(publickey, password)方法，填入已知的公钥和密码。
3. 打印结果，done

   import com.alibaba.druid.filter.config.ConfigTools;
   import com.alibaba.druid.util.DruidPasswordCallback;
   
   
   
   public class DesPassword extends DruidPasswordCallback {
   
       public static void main(String[] args) throws Exception{
           String publickey = 填入公钥;
           String password = 填入密码;
           String pwd = ConfigTools.decrypt(publickey, password);
   
           System.out.println(pwd);
       }
   }
