簡述php介面資料加密、解密、驗證簽章的用法

這篇文章主要介紹了php介面資料加密、解密、驗證簽名的相關資料,需要的朋友可以參考下

程式碼很簡單，這裡就不多廢話了，直接奉上程式碼

程式碼如下:

<?php
//header(&#39;Content-Type: text/xml; charset=utf-8&#39;);
include_once(dirname(dirname(__FILE__)).DIRECTORY_SEPARATOR.&#39;phpsec&#39;.DIRECTORY_SEPARATOR.&#39;Math&#39;.DIRECTORY_SEPARATOR.&#39;BigInteger.php&#39;);
include_once(dirname(dirname(__FILE__)).DIRECTORY_SEPARATOR.&#39;phpsec&#39;.DIRECTORY_SEPARATOR.&#39;Crypt&#39;.DIRECTORY_SEPARATOR.&#39;AES.php&#39;);
include_once(dirname(dirname(__FILE__)).DIRECTORY_SEPARATOR.&#39;phpsec&#39;.DIRECTORY_SEPARATOR.&#39;Crypt&#39;.DIRECTORY_SEPARATOR.&#39;RSA.php&#39;);
//密文
$crypttext = &#39;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&#39;;
