Shiro安全框架之加密工具

一、在util包下建个CryptographyUtil

package com.guo.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, "java1234"));
    }
}
