## 场景 ##

Shiro自带Base64和MD5加密。

Base64位置：

MD5位置：

## 实现 ##

新建测试类

package com.badao.util;
    
    import org.apache.shiro.codec.Base64;
    import org.apache.shiro.crypto.hash.Md5Hash;
    
    public class CryptographyUtil {
    
     /**
      * base64加密
      * @param str
      * @return
      */
     public static String encBase64(String str){
      return Base64.encodeToString(str.getBytes());
     }
     
     /**
      * base64解密
      * @param str
      * @return
      */
     public static String decBase64(String str){
      return Base64.decodeToString(str);
     }
     
     /**
      * Md5加密
      * @param str
      * @param salt
      * @return
      */
     public static String md5(String str,String salt){
      return new Md5Hash(str,salt).toString();
     }
     
     public static void main(String[] args) {
      String password="123456";
      System.out.println("Base64加密"+CryptographyUtil.encBase64(password));
      System.out.println("Base64解密"+CryptographyUtil.decBase64(CryptographyUtil.encBase64(password)));
      
      System.out.println("Md5加密"+CryptographyUtil.md5(password, "badao"));
     }
    }

### 运行结果 ###

注意：

MD5的加密是不可逆的，关于MD5在加密密码时的使用参照：
