我不知道如何实现这一目标。我驳回了可以将CSR与证书匹配的链接。
在此工具中，他们从证书和企业社会责任中获取哈希并匹配它们。所以我也试图获得哈希，但我无法获得适当的价值。
这是我的实现：
BufferedInputStream bufferedIS = new BufferedInputStream(mulitpartFile.getInputStream());
CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509");
Certificate certificate = certificateFactory.generateCertificate(bufferedIS);
X509Certificate x509Certificate = (X509Certificate) certificate;
String thumbprint = DigestUtils.sha512Hex(x509Certificate.getEncoded());
，但我没有得到确切的价值。
这是我的CSR和证书。

任何有想法实现这一目标的人，请帮助我。
您的代码从完整的证书x509Certificate.getEncoded()而不是公共密钥中创建哈希。
