as3实现MD5加密

2019-9-29 zhulinan Flash

建一个Action Script 3.0文档，目标设置为Flash Player 11.2。

舞台放置1个输入文本txt1，1个动态文本txt2，1个按钮btn1。文档的类设置为com.elight.Main。

com.elight.Main代码如下： package com.elight { import flash.display.MovieClip; import flash.events.*; import com.victop.MD5; public class Main extends MovieClip { public function Main() { addEventListener(Event.ADDED_TO_STAGE, addedHandle); } private function addedHandle(e:Event):void { removeEventListener(Event.ADDED_TO_STAGE, addedHandle); btn1.addEventListener(MouseEvent.CLICK, clickHandle); } private function clickHandle(e:MouseEvent):void { var s1:String = txt1.text; if (s1 == "") return; var md5:MD5 = new MD5; txt2.text = md5.getMD5(s1); } } }

com.victop.MD5代码如下： package com.victop { public class MD5 {  private var hexcase:int = 0; private var strsize:int = 8; public function getMD5(s:String):String { return binl2hex(core_md5(str2binl(s), s.length*strsize));
