我有类似的问题。我尝试使用移动签名签署 pdf。我在签名时使用 itextpdf-5.1.3.jar,bcprov-jdk16-1.46.jar。

X509Certificate root0 = Utils.getCert(PropertyUtils 
                                                .getProperty(Property.SIGN_ROOT_CERT0_PATH.value)); 
X509Certificate root1 = Utils.getCert(PropertyUtils 
                                                .getProperty(Property.SIGN_ROOT_CERT1_PATH.value)); 
X509Certificate[] chain =  {root1,root0};

我创建 pdfstamper ，将值设置为 PdfSignatureAppearance （我创建带有颁发者证书的 Cert.chain ）并预先关闭 PdfSignatureAppearance 以计算 pdf 的哈希值。我将此哈希发送到移动签名服务，他们将证书和签名值返回给我。比我添加了这个证书。链接并继续签名过程。

我的问题是当我用 adobe 打开 pdf 文件时，我只看到一个证书，我看不到其他两个根证书。我在它下面放了链接，其中包含我的代码、单个 pdf 和我使用的证书。你能帮助我吗 ？

更新

在图 1 中，我只看到一个证书。但我想在图 2 中看到。我怎样才能放置根证书。成pdf？

你好像混淆了什么。以下证书包含在 PDF 的 CMS 容器中（非 ASCII 字符可能有些混淆）：

第一个：

主题：序列号=20000000002,C=TR,CN=GÃœNAY DEMÄ°R

发行人：CN=Avea Mobil Nitelikli Elektronik Sertifika Hizmet Saglayicisi,O=Elektronik Bilgi Guvenligi AS,C=TR

第二

主题：CN=e-Guven Nitelikli Elektronik Sertifika Hizmet Saglayicisi,O=Elektronik Bilgi Guvenligi AS,C=TR

发行人：CN=e-Guven Kok Elektronik Sertifika Hizmet Saglayicisi,O=Elektronik Bilgi Guvenligi AS,C=TR

第三

主题：CN=Avea Mobil Nitelikli Elektronik Sertifika Hizmet Saglayicisi,O=Elektronik Bilgi Guvenligi AS,C=TR

发行人：CN=e-Guven Kok Elektronik Sertifika Hizmet Saglayicisi,O=Elektronik Bilgi Guvenligi AS,C=TR

第一个是签名者证书，第三个是中间 CA 证书，即您的“根 1.crt”，但第二个只是基于相同根证书的另一个 CA 证书。

您的投递箱中的实际根证书“root.cer”已丢失。

您可能想要检查引用您的根证书和 CA 证书的属性的值。

（为了清楚起见，您应该更改变量和文件的名称，以不将中间 CA 证书称为根证书。）
