<li>响应加密示例</li>
</ul>
<pre>encrypt==1时，响应包体使用<a class="external-link" href="https://gitlab.intra.knownsec.com/jiasule/jsl-httpdns/merge_requests/5" rel="nofollow">AES-256-ECB</a>方式加密，同时包体也使用pkcs7padding的16字节方式对齐。由于加密后的密文不都是可打印的，所以响应包体是由密文转换而来的16进制字符串，转换过程中每个密文字节由两个十六进制字符表示，如密文为"0123456789abcdef"则转换为十六进制字符串后为"30313233343536373839414243444546"。因此解密时需要先将十六进制字符串响应包体转换为原始密文。</pre>
