<p>知道创宇云平台仅支持*.pem格式的完整证书文件上传，若本地没有完整的pem文件，需要合成后再上传，若证书颁发商颁发的证书中存在*.pem文件，需核实证书链是否完整，即里面是否包含私钥，公钥和CA证书，如不完整，也需进行合成。</p>
<h3><strong>一、证书合成步骤</strong></h3>
<p>1.打开知道创宇<a href="https://defense.yunaq.com/tools/certificate_composing/">证书合成工具</a>。</p>
<p>2.打开本地证书文件，如果证书区分服务器类型，选择Nginx。</p>
<p>3.查看本地文件，一般包含ROOT证书、CA 证书、公钥、私钥。</p>
<p>4.按照以下顺序放入证书合成工具中。</p>
<p><img class="aligncenter size-full wp-image-4934" src="http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_18-2-43.png" alt="" width="838" height="576" srcset="http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_18-2-43.png 838w, http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_18-2-43-300x206.png 300w, http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_18-2-43-768x528.png 768w, http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_18-2-43-60x41.png 60w, http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_18-2-43-150x103.png 150w" sizes="(max-width: 838px) 100vw, 838px" /></p>
<p>如果没有ROOT证书，可以不勾选 “自动补全证书链” ，但若也没有CA证书，则需勾选 “自动补全证书链” 。</p>
<p><img class="aligncenter size-full wp-image-4938" src="http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_18-5-32.png" alt="" width="691" height="586" srcset="http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_18-5-32.png 691w, http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_18-5-32-300x254.png 300w, http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_18-5-32-60x51.png 60w, http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_18-5-32-150x127.png 150w" sizes="(max-width: 691px) 100vw, 691px" /></p>
<p>5.点击 “合并成pem格式” 后，右边会出现 “证书下载链接”，点击将合成后的证书进行下载。</p>
<p><img class="aligncenter size-full wp-image-4937" src="http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_17-55-58.png" alt="" width="674" height="207" srcset="http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_17-55-58.png 674w, http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_17-55-58-300x92.png 300w, http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_17-55-58-60x18.png 60w, http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_17-55-58-150x46.png 150w" sizes="(max-width: 674px) 100vw, 674px" /></p>
<p>6.证书下载之后，回到云防护控制台上传合成后的证书文件即可，点击查看<a href="http://help.yunaq.com/faq/3335/index.html">如何上传证书</a>。</p>
<h3><strong>二、合成举例</strong></h3>
<p><strong>例1</strong>：</p>
<p>1、本地文件如下，如有多个版本文件，选择Nginx或Apache版本</p>
<p><img class="confluence-embedded-image size-full wp-image-1633 confluence-external-resource aligncenter" src="http://help.yunaq.com/wp-content/uploads/2019/12/1576661476939.jpg" width="796" height="194" data-image-src="http://help.yunaq.com/wp-content/uploads/2019/12/1576661476939.jpg" srcset="http://help.yunaq.com/wp-content/uploads/2019/12/1576661476939.jpg 796w, http://help.yunaq.com/wp-content/uploads/2019/12/1576661476939-300x73.jpg 300w, http://help.yunaq.com/wp-content/uploads/2019/12/1576661476939-768x187.jpg 768w, http://help.yunaq.com/wp-content/uploads/2019/12/1576661476939-60x15.jpg 60w, http://help.yunaq.com/wp-content/uploads/2019/12/1576661476939-150x37.jpg 150w" sizes="(max-width: 796px) 100vw, 796px" /></p>
<p>2、打开后仅有两个文件，其中XXX.crt为公钥文件，XXX.key为私钥文件，分别使用本地文本编辑器打开，按顺序全选复制到合成工具中（本地cert文件打开后里面可能包含了中间证书）。</p>
<p><img class="confluence-embedded-image size-full wp-image-1635 confluence-external-resource aligncenter" src="http://help.yunaq.com/wp-content/uploads/2019/12/1576661779146.jpg" width="645" height="72" data-image-src="http://help.yunaq.com/wp-content/uploads/2019/12/1576661779146.jpg" srcset="http://help.yunaq.com/wp-content/uploads/2019/12/1576661779146.jpg 645w, http://help.yunaq.com/wp-content/uploads/2019/12/1576661779146-300x33.jpg 300w, http://help.yunaq.com/wp-content/uploads/2019/12/1576661779146-60x7.jpg 60w, http://help.yunaq.com/wp-content/uploads/2019/12/1576661779146-150x17.jpg 150w" sizes="(max-width: 645px) 100vw, 645px" /></p>
<p>3、因证书颁发商没有提供完整证书链，合成时可勾选 “自动补全证书链”，点击合成，合成后将文件下载，回到云防护控制台上传合成后的文件即可。<img class="aligncenter size-full wp-image-4935" src="http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_17-48-26.png" alt="" width="658" height="583" srcset="http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_17-48-26.png 658w, http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_17-48-26-300x266.png 300w, http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_17-48-26-60x53.png 60w, http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_17-48-26-150x133.png 150w" sizes="(max-width: 658px) 100vw, 658px" /><strong>例2：</strong></p>
<p>1、本地文件列表如下：<img class="confluence-embedded-image size-full wp-image-1637 confluence-external-resource aligncenter" src="http://help.yunaq.com/wp-content/uploads/2019/12/1576662277973.jpg" width="738" height="188" data-image-src="http://help.yunaq.com/wp-content/uploads/2019/12/1576662277973.jpg" srcset="http://help.yunaq.com/wp-content/uploads/2019/12/1576662277973.jpg 738w, http://help.yunaq.com/wp-content/uploads/2019/12/1576662277973-300x76.jpg 300w, http://help.yunaq.com/wp-content/uploads/2019/12/1576662277973-60x15.jpg 60w, http://help.yunaq.com/wp-content/uploads/2019/12/1576662277973-150x38.jpg 150w" sizes="(max-width: 738px) 100vw, 738px" /></p>
<p>2、分别使用本地文本编辑器打开，按顺序全选复制到合成工具中，因本地有完整证书链，不需要勾选 “自动补全证书链” 选项，点击合成，合成后将文件下载，回到云防护控制台上传合成后的文件即可。</p>
<p><img class="aligncenter size-full wp-image-4936" src="http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_17-53-57.png" alt="" width="833" height="583" srcset="http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_17-53-57.png 833w, http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_17-53-57-300x210.png 300w, http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_17-53-57-768x538.png 768w, http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_17-53-57-60x42.png 60w, http://help.yunaq.com/wp-content/uploads/2021/08/image2021-9-14_17-53-57-150x105.png 150w" sizes="(max-width: 833px) 100vw, 833px" /></p>

<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>
