js implémente le partage de code du plug-in de chiffrement md5

Cet article partage principalement avec vous l'implémentation js du code du plug-in de chiffrement md5, en espérant aider tout le monde.

//使用方法：
//引入文件<script src="yourURL/MD5.js" type="text/javascript" charset="utf-8"></script>
//var MD5=MD5.createMD5String（yourSrting）；(
	function(globle,factory){//判断执行环境是否为浏览器
		typeof window != "undefined" ? factory() : concole.log("当前环境不支持该插件");
	}
