我花了很长时间才使java签署CSR，最后我能够做到这一点，但openssl告诉它无效。与openssl签署的相同CSR通过验证步骤。
全部是相同的x509版本（1），没有扩展名，主题，发行人是相同的。
我怀疑问题出在主题DN（特别是电子邮件）或日期。
验证
openssl verify -verbose -CAfile src/test/resources/ca.cer.pem o.cer.pem
o.cer.pem: OK
openssl verify -verbose -CAfile src/test/resources/ca.cer.pem client.cer.pem
client.cer.pem: C = RU, ST = Moscow, L = Moscow, O = Hoofs, OU = IT, CN = Danee Yaitskov
error 20 at 0 depth lookup:unable to get local issuer certificate
文件大小相似：
1229 Jul 28 12:45 client.cer.pem 1233年7月28日13:00 o.cer.pem
它抱怨链条中缺少证书，但我没有看到这样的信息。
如何检查下一个父证书是什么？
关于良好证书的信息：
openssl x509 -in o.cer.pem -text -noout

我有一个类似的例子
尝试使用从CA获取的X500名称替换X500Name issuer =，以避免出现字符问题
X500Name issuer = X500Name.getInstance(cacert.getSubjectX500Principal().getEncoded());
另外，我认为在PEM编码之前你需要这个部分
CMSSignedDataGenerator generator = new CMSSignedDataGenerator();
signer = new JcaContentSignerBuilder("SHA1withRSA").build(cakey);
generator.addSignerInfoGenerator(new JcaSignerInfoGeneratorBuilder(new JcaDigestCalculatorProviderBuilder().build()).build(signer, cacert));
generator.addCertificate(new X509CertificateHolder(certencoded));
generator.addCertificate(new X509CertificateHolder(cacert.getEncoded()));
CMSTypedData content = new CMSProcessableByteArray(certencoded);
CMSSignedData signeddata = generator.generate(content, true);
byte signedCertificate[] = signeddata.getEncoded();
