[http://www.gongjuji.net/Content/files/jquery.md5.js][http_www.gongjuji.net_Content_files_jquery.md5.js]

引入[js][]后

使用方法：

**\[javascript\]**  view plain  copy

print ?

1.  document.write($.md5('1234'));

document.write($.md5('1234'));

加密结果：

**\[html\]**  view plain  copy

print ?

1.  81dc9bdb52d04dc20036dbd8313ed055

81dc9bdb52d04dc20036dbd8313ed055

打开MD5在线工具

有时候我们想在js里面使用加密，jQuery就提供了这样的插件，用法十分简单：

$(md("你想要加密的字符串"));

md5插件下载地址：[http://plugins.jquery.com/project/md5][http_plugins.jquery.com_project_md5]

下面是我的简单例子

/\*\*  
 \* jQuery MD5 hash algorithm function  
 \*  
 \*     <code>  
 \*         Calculate the md5 hash of a String  
 \*         String $.md5 ( String str )  
 \*     </code>  
 \*  
 \* Calculates the MD5 hash of str using the 禄 RSA Data Security, Inc. MD5 Message-Digest Algorithm, and returns that hash.  
 \* MD5 (Message-Digest algorithm 5) is a widely-used cryptographic hash function with a 128-bit hash value. MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of data. The generated hash is also non-reversable. Data cannot be retrieved from the message digest, the digest uniquely identifies the data.  
 \* MD5 was developed by Professor Ronald L. Rivest in 1994. Its 128 bit (16 byte) message digest makes it a faster implementation than SHA-1.  
 \* This script is used to process a variable length message into a fixed-length output of 128 bits using the MD5 algorithm. It is fully compatible with UTF-8 encoding. It is very useful when u want to transfer encrypted passwords over the internet. If you plan using UTF-8 encoding in your project don't forget to set the page encoding to UTF-8 (Content-Type meta tag).  
 \* This function orginally get from the WebToolkit and rewrite for using as the jQuery plugin.  
 \*  
 \* Example  
 \*     Code  
 \*         <code>  
 \*             $.md5("I'm Persian.");  
 \*         </code>  
 \*     Result  
 \*         <code>  
 \*             "b8c901d0f02223f9761016cfff9d68df"
