JS实现Base64加密解密、MD5加密、SHA1加密

<!-- base64加密解密 -->
<script type="text/javascript" src="base64.js"></script>
<script type="text/javascript">  
    var b = new Base64();  
    //加密
    var str = b.encode("admin:admin");  
    alert("base64 encode:" + str);  
　　//解密
    str = b.decode(str);  
    alert("base64 decode:" + str);  
</script> 
 
<!-- MD5加密 -->
<script type="text/ecmascript" src="md5.js"></script>
<script type="text/javascript">  
    var hash = hex_md5("123dafd");
    alert(hash);
</script> 
 
<!-- SHA1加密 -->
<script type="text/ecmascript" src="sha1.js"></script>
<script type="text/javascript">
    var sha = hex_sha1('mima123465');
    alert(sha);
</script>
