Briefly describe the usage of data encryption, decryption and signature verification in PHP interface

This article mainly introduces the relevant information on PHP interface data encryption, decryption, and signature verification. Friends who need it can refer to it

The code is very simple, there will be no more nonsense here, just provide the code

The code is as follows:

<?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;;
