Java/Keystore验证签名证书

Question

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:

    ... 4 more

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.
