尝试通过 java 驱动程序连接时 mongodb 服务器上的 SSLHandshakeFailed

Question

我一直在尝试通过 java 驱动程序将 mongodb 服务器与 TLS 1.2 连接，但是我无法理解为什么握手失败。 这是我的设置

• MongoDB 服务器 4.2.1
• mongod.conf：

net:
   bindIp: 127.0.0.1
   port: 27017

   tls:
    mode: requireTLS
    CAFile: <location-to-ca.crt>
    certificateKeyFile: <location-to-server.pem>
    disabledProtocols: TLS1_0,TLS1_1

• JDK：1.8.0_202
• mongo-java-驱动程序：3.12.3

private static void Tls1_2Test() throws Exception {
    SSLContext sslContext = createSSLContext();
    MongoClientSettings settings = MongoClientSettings.builder()
            .applyToSslSettings(builder -> {
                builder.enabled(true);
                builder.context(sslContext);
                builder.invalidHostNameAllowed(true);
            })
            .build();
    try (MongoClient client = MongoClients.create(settings)) {
        for (String s : client.listDatabaseNames()) {
            System.out.println(s);
        }
    }
    catch (Exception e) {
        e.printStackTrace();
    }
}

public static SSLContext createSSLContext() throws Exception {

    // root CA
    TrustManagerFactory tmf;
    try (InputStream is = new FileInputStream("<location-to-ca.crt>")) {
        CertificateFactory cf = CertificateFactory.getInstance("X.509");
        X509Certificate caCert = (X509Certificate) cf.generateCertificate(is);
        tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());
        ks.load(null); // You don't need the KeyStore instance to come from a file.
        ks.setCertificateEntry("caCert", caCert);
        tmf.init(ks);
    }

    // client key
    KeyManagerFactory keyFac;
    try (InputStream is = Test.class.getResourceAsStream("<location-to-client.pem>")) {
        KeyStore keystore = KeyStore.getInstance(KeyStore.getDefaultType());
        keystore.load(is, null);
        keyFac = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
        keyFac.init(keystore, null);
    }

    SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
    sslContext.init(keyFac.getKeyManagers(), tmf.getTrustManagers(), null);

    return sslContext;
}

• 密钥生成器

如果我不使用 CAFile 或在配置中使用allowConnectionsWithoutCertificates: true ，我可以连接，因为服务器不负责握手的可信授权。 但是，我找不到 java 代码有什么问题，因此服务器没有获得用于握手的 CA 证书。

请注意，mongod 配置中的 net.tls.CAFile 和 java 代码上的根 CA 指向同一个文件。 我也尝试在 net.tls.CAFile 中使用.pem 文件，但得到了相同的结果。

经过一番挖掘，我发现不是仅仅使用Keystore（因为我没有设置任何要使用的Keystore）我使用bouncy castle读取客户端文件。 使用 bouncycastle 1.65 版本。 这是我实现它的方法：

我将客户端文件读取更新为以下内容

// client key
KeyManagerFactory keyFac;
try (FileReader fr = new FileReader("<location-to-client.pem>")) {
    KeyStore keystore = KeyStore.getInstance(KeyStore.getDefaultType());
    keystore.load(null); // needs to be initialised, otherwise throws exception
    PEMParser pemParser = new PEMParser(fr);
    PrivateKeyInfo privateKeyInfo = (PrivateKeyInfo) pemParser.readObject();
    JcaPEMKeyConverter converter = new JcaPEMKeyConverter();
    PrivateKey privateKey = converter.getPrivateKey(privateKeyInfo);
    JcaX509CertificateConverter certConverter = new JcaX509CertificateConverter();
    X509CertificateHolder certificateHolder = (X509CertificateHolder) pemParser.readObject();
    X509Certificate certificate = certConverter.getCertificate(certificateHolder);
    keystore.setKeyEntry("alias", privateKey, "".toCharArray(), new Certificate[]{certificate});
    keyFac = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
    keyFac.init(keystore, "".toCharArray());
}
