我需要从我前面提到的文件中获得签名者的证书和OCSP响应。下面是我用来获取签署者的证书和与证书有关的数据的代码（用Java编写）：

    public static void main(String[] args) throws Exception {
            File xmlFile = new File("signatures0.xml");
            DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
            DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
            Document doc = dBuilder.parse(xmlFile);
            doc.getDocumentElement().normalize();
            NodeList nodeList = doc.getElementsByTagName("ds:X509Certificate");
            for (int itr = 0; itr < nodeList.getLength(); itr++) {
                Node node = nodeList.item(itr);
                String encodedBlock = node.getTextContent().replace("\n", "");
                byte[] decodedBlock = Base64.getDecoder().decode(encodedBlock.getBytes(StandardCharsets.UTF_8));
                ByteArrayInputStream inputStream = new ByteArrayInputStream(decodedBlock);

                CertificateFactory certFactory = CertificateFactory.getInstance("X.509");
                X509Certificate cert = (X509Certificate) certFactory.generateCertificate(inputStream);
                System.out.println(cert.getIssuerDN());
                System.out.println(cert.getSubjectX500Principal().toString());
                System.out.println(cert.getPublicKey());
                cert.checkValidity();
            }

  }

实际上，我不完全了解您的需求。但是，我认为要获得清晰的结构可以提取数据，最好使用pki协议库，例如openssl和Bouncy Castle。

这些开放源代码为您提供了将Base64编码的字符串转换为组织良好且易于使用的Class（s​​tructure）。

因此，请在您的项目中导入boundcy城堡，并使用下面提供的简单api。请注意，以下是一个示例，它可能会提供pem api。如果不是，则需要pem der转换。
