前端常用的加密方法

1.base64加密：

 1 <!DOCTYPE HTML>
 2 <html>
 3 <head>
 4 <meta charset="utf-8">
 5 <title>base64加密</title>
 6 <script type="text/javascript" src="base64.js"></script>
 7 <script type="text/javascript">  
 8         var b = new Base64();  
 9         var str = b.encode("admin:admin");  
10         alert("base64 encode:" + str);  
11 　　　　　//解密
12         str = b.decode(str);  
13         alert("base64 decode:" + str);  
14 </script>  
15 </head>
16 
17 <body>
18 </body>
19 </html>

2.md5加密：

 1 <!DOCTYPE HTML>
 2 <html>
 3 <head>
 4 <meta charset="utf-8">
 5 <title>md5加密</title>
 6 <script type="text/ecmascript" src="md5.js"></script>
 7 <script type="text/javascript">  
 8   var hash = hex_md5("123dafd");
 9     alert(hash)
10 </script>  
11 </head>
12 
13 <body>
14 </body>
15 </html>

3.sha1加密：

 1 <!DOCTYPE HTML>
 2 <html>
 3 <head>
 4 <meta charset="utf-8">
 5 <title>sha1加密</title>
 6 <script type="text/ecmascript" src="sha1.js"></script>
 7 <script type="text/javascript">
 8   var sha = hex_sha1('mima123465')
 9     alert(sha)   
10 </script>  
11 </head>
12 
13 <body>
14 </body>
