KeyStore和KeyManager / TrustManager之间的区别

Question

为密钥库和信任库使用KeyStore对象有什么区别;而不是使用KeyManager和TrustManager？

让我解释一下我的要求。我正在使用RESTEasy，需要通过HTTPS使用SSL证书进行REST调用。我需要增加RESTEasy如何创建ClientRequest。这是我最初想到的：

public void afterPropertiesSet() throws Exception {
    Assert.isTrue(StringUtils.isNotBlank(getKeystoreName()), "Key Store Name is Blank");
    Assert.isTrue(StringUtils.isNotBlank(getKeystorePassword()), "Key Store Password is Blank.");
    Assert.isTrue(StringUtils.isNotBlank(getKeystorePath()), "Key Store Path is Blank");
    Assert.isTrue(StringUtils.isNotBlank(getTruststoreName()), "Trust Store Name is Blank");
    Assert.isTrue(StringUtils.isNotBlank(getTruststorePassword()), "Trust Store Password is Blank.");
    Assert.isTrue(StringUtils.isNotBlank(getTruststorePath()), "Trust Store Path is Blank");

    // Set the keystore and truststore for mutual authentication
    createKeystore();
    createTruststore();

    if (getHttpClient() == null) {
        // Initialize HTTP Client
        initializeHttpClient();
    }

    Assert.notNull(getHttpClient(), "HTTP Client is NULL after initialization");
}

public ClientRequest createClientRequest(String uri) throws URISyntaxException {
    ClientExecutor clientExecutor = new ApacheHttpClient4Executor(getHttpClient());
    ClientRequestFactory fac = new ClientRequestFactory(clientExecutor, new URI(uri));
    return fac.createRequest(uri);
}

private void createTruststore() throws KeyStoreException, FileNotFoundException, IOException,
        NoSuchAlgorithmException, CertificateException {

    String truststoreFilePath = getTruststorePath() + getTruststoreName();

    KeyStore truststore = KeyStore.getInstance(KeyStore.getDefaultType());
    InputStream truststoreInput = getClass().getClassLoader().getResourceAsStream(truststoreFilePath);
    truststore.load(truststoreInput, getTruststorePassword().toCharArray());
}

private void createKeystore() throws KeyStoreException, FileNotFoundException, IOException,
        NoSuchAlgorithmException, CertificateException {

    String keystoreFilePath = getKeystorePath() + getKeystoreName();
    KeyStore keystore = KeyStore.getInstance(KeyStore.getDefaultType());
    InputStream keystoreInput = getClass().getClassLoader().getResourceAsStream(keystoreFilePath);
    keystore.load(keystoreInput, getKeystorePassword().toCharArray());
}

/**
 * Initializes the HTTP Client
 * 
 * @throws KeyStoreException
 * @throws NoSuchAlgorithmException
 * @throws UnrecoverableKeyException
 * @throws KeyManagementException
 */
private void initializeHttpClient() throws KeyManagementException, UnrecoverableKeyException,
        NoSuchAlgorithmException, KeyStoreException {

    // Register https and http with scheme registry
    SchemeRegistry schemeRegistry = new SchemeRegistry();
    SSLSocketFactory sslSocketFactory = new SSLSocketFactory(getKeystore(), getKeystorePassword(), getTrustStore());
    schemeRegistry.register(new Scheme(HTTP, 80, PlainSocketFactory.getSocketFactory()));
    schemeRegistry.register(new Scheme(HTTPS, 443, sslSocketFactory));

    // Set connection params
    HttpConnectionParams.setConnectionTimeout(httpParameters, serviceConnectionTimeout);
    HttpConnectionParams.setSoTimeout(httpParameters, readTimeout);
    HttpConnectionParams.setStaleCheckingEnabled(httpParameters, true);

    // Create Connection Manager
    PoolingClientConnectionManager clientManager = new PoolingClientConnectionManager(schemeRegistry);
    clientManager.setMaxTotal(maxTotalConnections);
    clientManager.setDefaultMaxPerRoute(defaultMaxConnectionsPerHost);

    httpClient = new DefaultHttpClient(clientManager, httpParameters);
}

我遇到了对等证书的问题并且一直有例外：

  

javax.net.ssl.SSLPeerUnverifiedException：peer not authenticated

然后我搜索了一下有关设置HttpClient但使用TrustManager和KeyManager的文章/博客。我重构了代码以执行以下操作：

public void afterPropertiesSet() throws Exception {
    Assert.isTrue(StringUtils.isNotBlank(getKeystoreName()), "Key Store Name is Blank");
    Assert.isTrue(StringUtils.isNotBlank(getKeystorePassword()), "Key Store Password is Blank.");
    Assert.isTrue(StringUtils.isNotBlank(getKeystorePath()), "Key Store Path is Blank");
    Assert.isTrue(StringUtils.isNotBlank(getTruststoreName()), "Trust Store Name is Blank");
    Assert.isTrue(StringUtils.isNotBlank(getTruststorePassword()), "Trust Store Password is Blank.");
    Assert.isTrue(StringUtils.isNotBlank(getTruststorePath()), "Trust Store Path is Blank");

    if (getHttpClient() == null) {
        // Initialize HTTP Client
        initializeHttpClient();
    }

    Assert.notNull(getHttpClient(), "HTTP Client is NULL after initialization");
}

public ClientRequest createClientRequest(String uri) throws URISyntaxException {
    ClientExecutor clientExecutor = new ApacheHttpClient4Executor(getHttpClient());
    ClientRequestFactory fac = new ClientRequestFactory(clientExecutor, new URI(uri));
    return fac.createRequest(uri);
}

/**
 * Initializes the HTTP Client
 * 
 * @throws KeyStoreException
 * @throws NoSuchAlgorithmException
 * @throws UnrecoverableKeyException
 * @throws KeyManagementException
 */
private void initializeHttpClient() throws Exception {

    if (isCheckPeerCertificates()) {
        checkPeerCerts();
    }

    // Create Trust and Key Managers
    // Use TrustManager and KeyManager instead of KeyStore
    TrustManager[] trustManagers = getTrustManagers(getTruststorePassword());
    KeyManager[] keyManagers = getKeyManagers(getKeystorePassword());

    // Create SSL Context
    SSLContext ctx = SSLContext.getInstance("TLS");
    ctx.init(keyManagers, trustManagers, new SecureRandom());

    // Create SSL Factory
    SSLSocketFactory sslSocketFactory = new SSLSocketFactory(ctx, SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

    // Register https and http with scheme registry
    SchemeRegistry schemeRegistry = new SchemeRegistry();
    schemeRegistry.register(new Scheme(HTTP, 80, PlainSocketFactory.getSocketFactory()));
    schemeRegistry.register(new Scheme(HTTPS, 443, sslSocketFactory));

    // Set connection params
    HttpConnectionParams.setConnectionTimeout(httpParameters, serviceConnectionTimeout);
    HttpConnectionParams.setSoTimeout(httpParameters, readTimeout);
    HttpConnectionParams.setStaleCheckingEnabled(httpParameters, true);

    // Create Connection Manager
    PoolingClientConnectionManager clientManager = new PoolingClientConnectionManager(schemeRegistry);
    clientManager.setMaxTotal(maxTotalConnections);
    clientManager.setDefaultMaxPerRoute(defaultMaxConnectionsPerHost);

    httpClient = new DefaultHttpClient(clientManager, httpParameters);
}

private TrustManager[] getTrustManagers(String trustStorePassword) throws Exception {
    String truststoreFilePath = getTruststorePath() + getTruststoreName();
    InputStream trustStoreInput = getClass().getClassLoader().getResourceAsStream(truststoreFilePath);
    KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
    trustStore.load(trustStoreInput, trustStorePassword.toCharArray());
    TrustManagerFactory tmfactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
    tmfactory.init(trustStore);
    return tmfactory.getTrustManagers();
}

private KeyManager[] getKeyManagers(String keyStorePassword) throws Exception {
    String keystoreFilePath = getKeystorePath() + getKeystoreName();
    InputStream keyStoreInput = getClass().getClassLoader().getResourceAsStream(keystoreFilePath);
    KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
    keyStore.load(keyStoreInput, keyStorePassword.toCharArray());
    KeyManagerFactory kmfactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
    kmfactory.init(keyStore, keyStorePassword.toCharArray());
    return kmfactory.getKeyManagers();
}

第二个代码工作得很好。那么，两种用法之间有什么区别？

Answer 1

我认为这可以帮到你： Difference between trustStore and keyStore in Java - SSL

  

trustStore和keyStore之间的第一个主要区别是TrustManager使用trustStore，Java中的KeyManager类使用keyStore。 KeyManager和TrustManager在Java中执行不同的工作，TrustManager确定是否应该信任远程连接，即远程方是否是它声称的人，并且KeyManager决定在SSL握手期间应将哪些认证凭证发送到远程主机以进行认证。如果您是SSL服务器，您将在密钥交换算法期间使用私钥并将与您的公钥对应的证书发送到客户端，此证书是从keyStore获取的。在SSL客户端，如果用Java编写，它将使用存储在trustStore中的证书来验证服务器的身份。
