这篇文章主要介绍了php接口数据加密、解密、验证签名的相关资料,需要的朋友可以参考下，代码很简单，这里就不多废话了，直接奉上代码:

1. <?php 
2. //header('Content-Type: text/xml; charset=utf-8'); 
3. include_once(dirname(dirname(__FILE__)).DIRECTORY_SEPARATOR.'phpsec'.DIRECTORY_SEPARATOR.'Math'.DIRECTORY_SEPARATOR.'BigInteger.php'); 
4. include_once(dirname(dirname(__FILE__)).DIRECTORY_SEPARATOR.'phpsec'.DIRECTORY_SEPARATOR.'Crypt'.DIRECTORY_SEPARATOR.'AES.php'); 
5. include_once(dirname(dirname(__FILE__)).DIRECTORY_SEPARATOR.'phpsec'.DIRECTORY_SEPARATOR.'Crypt'.DIRECTORY_SEPARATOR.'RSA.php'); 
6. //密文 
7. $crypttext = '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';
