Linux平台PHP的加解密扩展库开发
PHP是现在比较流行的服务器端软件，通过PHP编制的动态网页应用十分广泛，实现PHP的加解密技术尤为重要。PHP有丰富的函数库，一般情况下已经够我们使用，但为了注重加解密的效率，如复杂的信息加解密算法，需要编写成PHP扩展。本文讨论了在 Linux平台 PHP的加解密扩展库的开发，对 Linux平台和 PHP 的应用情况做了相应的介绍，编译安装PHP模块并加载加密模块进PHP，最后通过聊天室PHP来测试加密模块的加密和解密方法的使用。

Linux platform PHP encryption extensions library development
Abstract:
Linux operating system is an open source operating system for free ， It has the characteristics of safety， stability and low cost. With the rapid development of the Internet ， spread the Linux operating system in our country， more and more servers， workstations and personal computers began using Linux software ， therefore under the Linux operating system of data encryption in the position has been more and more important in our life，especially given the large number of transactions taking place on the Internet and transmission of large amounts of data，to take safety measures is very necessary . This article choose in Linux platform encryption extension libraries of PHP development .
PHP is now more popular server-side software， compiled by PHP dynamic web application is very extensive， implement PHP encryption technology is particularly important . PHP has abundant function library， usually we use enough， but to pay attention to the efficiency of encryption， such as complex encryption algorithm， you need to write a PHP extension . This paper discusses on the Linux platform PHP encryption extensions library development， the Linux platform and PHP application made corresponding introduction ， compile the installing PHP module and load encryption module in PHP ， finally through the chat room PHP to test the use of encryption and decryption method of encryption module .
Keywords: Linux operating system; PHP extensions; RC5 algorithm; PHP chat room
