angular进行md5加密

1、引入文件encrypt.js
2、注入模块

var DiagnoseApp = angular.module('DiagnoseApp',['ui.router','ngCookies','ngFileUpload','Encrypt']);

3、引用

DiagnoseApp.controller('NavbarCtrl',function($scope,$rootScope,$http,$location,$timeout,$interval,Md5,Base64,Sha1) {
  // MD5加密当前日期
  $scope.md5Value=Md5.hex_md5(new Date());
})

encrypt.js 文件内容如下：
