1、base64加密：在页面中引入base64.js文件，调用方法为：
<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<title>base64加密</title>
<script type="text/javascript" src="base64.js"></script>
<script type="text/javascript">
var b = new Base64();
var str = b.encode("admin:admin");
alert("base64 encode:" + str);
//解密
str = b.decode(str);
console.log("base64 decode:" + str);
</script>
</head>
<body>
</body>
</html>
2、md5加密 ：在页面中引用md5.js文件，调用方法为
<!DOCTYPE HTML> <html> <head> <meta charset="utf-8"> <title>md5加密</title> <script type="text/ecmascript" src="md5.js"></script> <script type="text/javascript"> var hash = hex_md5("123dafd"); console.log(hash) </script> </head> <body> </body> </html>
3、sha1加密：页面中引入sha1.js（据说这是最安全的加密），调用方法为
<!DOCTYPE HTML> <html> <head> <meta charset="utf-8"> <title>sha1加密</title> <script type="text/ecmascript" src="sha1.js"></script> <script type="text/javascript"> var sha = hex_sha1('mima123465') console.log(sha) </script> </head> <body> </body> </html>
