证书链未传输到服务器

Question

我使用此方法将客户端证书注册到服务器证书中。

/**
 * Links the user's certificate into the server's keystore/truststore.
 * 
 * @param server
 *            The server party.
 * @return <code>true</code> if the certificate has been bound,
 *         <code>false</code> if the certificate already was bound to the
 *         truststore.
 * @throws KeyStoreException
 */
public boolean linkToServerCertificate(Party server) throws KeyStoreException {
    if (keyAlias.equals(server.keyAlias)) {
        throw new IllegalArgumentException("The alias of client and server must be different!");
    }
    keystore.setCertificateEntry(server.keyAlias, server.getAliasCert());
    Certificate certificate = keystore.getCertificate(keyAlias);
    server.keystore.setCertificateEntry(keyAlias, certificate);
    return true;
}

重新启动后，我得到以下消息：

​

​

有了环境变量JAVA_OPTS="-Djavax.net.debug=ssl“，我得到了以下信息：

*** ServerHelloDone
https-jsse-nio-8443-exec-7, WRITE: TLSv1.2 Handshake, length = 1522
https-jsse-nio-8443-exec-8, READ: TLSv1.2 Handshake, length = 7
*** Certificate chain
<Empty>
***
https-jsse-nio-8443-exec-8, fatal error: 42: null cert chain
javax.net.ssl.SSLHandshakeException: null cert chain
%% Invalidated:  [Session-4, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256]
https-jsse-nio-8443-exec-8, SEND TLSv1.2 ALERT:  fatal, description = bad_certificate

所以证书的证书链是空的。

但是检查客户端上的证书，它指出存在一个证书链。

我很困惑，为什么证书链不被传输到服务器？

Answer 1

我犯了错误，我把证书链订错了。

keystore.setKeyEntry(alias, pair.getPrivate(), pass.toCharArray(), 
         chainSet.toArray(new Certificate[0]));

chainSet必须按照最近的证书是第一个证书的顺序。

真正的错误是使用内置的pki实现。

Answer 2

您可以复制完整的证书链，如下所示。

Key key = keystore.getKey(keyAlias, clientKeyStorePassPhrase);
Certificate[] chain = keystore.getCertificateChain(keyAlias);
server.keystore.setKeyEntry(keyAlias, key, serverKeyStorePassPhrase, chain);

更新-

Java还建议keystore.getCertificate(keyAlias);只返回证书链的第一个元素。参考文献- https://docs.oracle.com/javase/8/docs/api/index.html?java/security/KeyStore.html
