js中实现加密

JS实现密码加密

1、base64加密

　　在页面中引入base64.js文件，调用方法为：

　　　

DOCTYPE HTML>
<</SPAN>html>
<</SPAN>head>
<</SPAN>meta charset="utf-8">
<</SPAN>title>base64加密</</SPAN>title>
<</SPAN>script type="text/javascript" src="base64.js"></</SPAN>script>
<</SPAN>script type="text/javascript">
var b = new Base64();
var str = b.encode("admin:admin");

alert("base64 encode:" + str);

　　　　　//解密

str = b.decode(str);

alert("base64 decode:" + str);
</</SPAN>script>
</</SPAN>head>

<</SPAN>body>
</</SPAN>body>
</</SPAN>html>

 

2、md5加密

　　在页面中引用md5.js文件，调用方法为

　　

DOCTYPE HTML>
<</SPAN>html>
<</SPAN>head>
<</SPAN>meta charset="utf-8">
<</SPAN>title>md5加密</</SPAN>title>
<</SPAN>script type="text/ecmascript" src="md5.js"></</SPAN>script>
<</SPAN>script type="text/javascript">
var hash = hex_md5("123dafd");

alert(hash)
</</SPAN>script>
</</SPAN>head>

<</SPAN>body>
</</SPAN>body>
</</SPAN>html>

 

3、sha1加密

　　据说这是最安全的加密

　　页面中引入sha1.js，调用方法为

　　

DOCTYPE HTML>
<</SPAN>html>
<</SPAN>head>
<</SPAN>meta charset="utf-8">
<</SPAN>title>sha1加密</</SPAN>title>
<</SPAN>script type="text/ecmascript" src="sha1.js"></</SPAN>script>
<</SPAN>script type="text/javascript">
var sha = hex_sha1('mima123465')

alert(sha)
</</SPAN>script>
</</SPAN>head>

<</SPAN>body>
</</SPAN>body>
</</SPAN>html>

 

base64.js

md5.js

sha1.js
