Java / Keystore验证签名证书

我正在研究嵌入式码头服务器和客户端之间的客户端证书身份验证 . 他们都使用密钥库 . 客户端证书由服务器的证书签名，该证书由CA签名 . Jetty使用2方法来验证客户端证书，javax.net.ssl.SSLEngine似乎工作，他们也使用上面的代码 .

List<X509Certificate> certList = Certificate chain sent by the client
KeyStore truststore = server's truststore

//No use of CRL/OSCP/CRLDP
_crls = null;
_enableOCSP = false;
_enableCRLDP = false;

try{
 X509CertSelector certSelect = new X509CertSelector();
 certSelect.setCertificate((X509Certificate) certList.get(0));

 // Configure certification path builder parameters
 PKIXBuilderParameters pbParams = new PKIXBuilderParameters(truststore, certSelect);
 pbParams.addCertStore(CertStore.getInstance("Collection", new CollectionCertStoreParameters(certList)));

 // Set maximum certification path length
 pbParams.setMaxPathLength(-1);

 // Enable revocation checking
 pbParams.setRevocationEnabled(true);

 // Set static Certificate Revocation List
 if (_crls != null && !_crls.isEmpty())
     pbParams.addCertStore(CertStore.getInstance("Collection", new CollectionCertStoreParameters(_crls)));

  // Enable On-Line Certificate Status Protocol (OCSP) support
  if (_enableOCSP)
      Security.setProperty("ocsp.enable","true");

  // Enable Certificate Revocation List Distribution Points (CRLDP) support
  if (_enableCRLDP)
      System.setProperty("com.sun.security.enableCRLDP","true");

 // Build certification path
 CertPathBuilderResult buildResult = CertPathBuilder.getInstance("PKIX").build(pbParams);               

 // Validate certification path
 CertPathValidator.getInstance("PKIX").validate(buildResult.getCertPath(),pbParams);
}catch(GeneralSecurityException gse){
 ...
}

当然我必须使用第二种方式...所以让我们专注于这个代码，这是验证签名证书的好方法吗？这是我的密钥库的转储：

客户端密钥库：

Entry type: PrivateKeyEntry 
Certificate chain length: 2
Certificate[1]: 
Owner: EMAILADDRESS=truc@ok.com, CN=Servlet, OU=dev, O=Imbasoft, ST=Ile-de-France, C=FR 
Issuer: EMAILADDRESS=contact@greenpacs.com, CN=Greenpacs, OU=dev, O=Imbasoft, L=Bondy, ST=Ile-de-France, C=FR 
...

Certificate[2]: 
Owner: EMAILADDRESS=contact@greenpacs.com, CN=Greenpacs, OU=dev, O=Imbasoft, L=Bondy, ST=Ile-de-France, C=FR
Issuer: EMAILADDRESS=ghetolay@imbasoft.com, CN=Greenpacs Certificate Authority, OU=dev, O=Imbasoft, ST=Ile-de-France, C=FR 
...

服务器信任库：

Entry type: trustedCertEntry

Owner: EMAILADDRESS=contact@greenpacs.com, CN=Greenpacs, OU=dev, O=Imbasoft, L=Bondy, ST=Ile-de-France, C=FR
Issuer: EMAILADDRESS=ghetolay@imbasoft.com, CN=Greenpacs Certificate Authority, OU=dev, O=Imbasoft, ST=Ile-de-France, C=FR

我不确定这些密钥库，但我尝试使用不同的密钥库（将CA证书添加到客户端的证书链，将证书添加到信任库），验证仍然失败 . 使用这些密钥库，第一种验证方法（SSLEngine）似乎有效 .

调试输出太大，无法放在这里，但这里是stacktrace：

如果我禁用撤销或者如果我将最后一个证书（而不是第一个）设置为X509CertSelector代码工作但我不确定我在做什么 .

我开始怀疑码头代码，但我不是证书和SSL握手方面的专家，所以它也可能来自糟糕的密钥库/信任库 . 这就是为什么我没有在码头上创建问题并在此之前询问，以确保代码需要更改 .

此外，了解如何在Java中验证签名证书可能很有用 .
