Java SSL/TLS忽略过期证书？（java.security.cert.CertPathValidatorException：时间戳检查失败）

我在使用一个通过SSL通信的API时遇到了问题。我认为出现异常的原因是SSL证书已过期。但问题是我不管理API服务器。是否有可能忽略过期的证书？

异常：

目前的代码需要能够设置信任库，因为存在客户端证书认证。我已经尝试了以下建议，但仍然遇到一些问题。这是我目前使用的代码：

        KeyStore identityStore = KeyStore.getInstance(KeyStore.getDefaultType());
        ClassPathResource keystore = new ClassPathResource(cadaBackendCertFile);

        identityStore.load(keystore.getInputStream(), cadaBackendCertFilePassword.toCharArray());

        KeyManagerFactory kmf = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
        kmf.init(identityStore, cadaBackendCertFilePassword.toCharArray());

        TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        tmf.init(identityStore);

        SSLContext ctx = SSLContext.getInstance("TLS");
        ctx.init(kmf.getKeyManagers(), tmf.getTrustManagers(), new SecureRandom());

        SSLSocketFactory fac = ctx.getSocketFactory();
        Socket sslsock = fac.createSocket(cadaBackendEndpoint, cadaBackendPort);
        TTransport transport = new TSocket(sslsock);

将代码更改为以下内容，虽然会出现服务器问题，但它解决了我的安全异常问题：

        KeyStore identityStore = KeyStore.getInstance(KeyStore.getDefaultType());
        ClassPathResource keystore = new ClassPathResource(cadaBackendCertFile);

        identityStore.load(keystore.getInputStream(), cadaBackendCertFilePassword.toCharArray());

        KeyManagerFactory kmf = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
        kmf.init(identityStore, cadaBackendCertFilePassword.toCharArray());

        TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        tmf.init(identityStore);

        SSLContext ctx = SSLContext.getInstance("TLS");
        ctx.init(kmf.getKeyManagers(), new TrustManager[] {new X509TrustManager(){
            public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }
            public void checkServerTrusted(X509Certificate[] chain,String authType) throws CertificateException {               
            }
            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }       
        }}, new SecureRandom());

        SSLSocketFactory fac = ctx.getSocketFactory();
        Socket sslsock = fac.createSocket(cadaBackendEndpoint, cadaBackendPort);
        TTransport transport = new TSocket(sslsock);

        TProtocol proto = new TBinaryProtocol(transport);
        cadaBackendClient = new Client(proto);

实际上 - 即使是上面的代码也会抛出异常：

在您的编辑版本中，您正在为keymanager和trustmanager使用相同的密钥库（这可能是有意的，不确定）。如果您没有使用客户端证书身份验证，则不需要它，请使用SSLContext.init（...）的第一个参数作为null。如果服务器可选请求客户端证书身份验证，并且客户端发送了服务器不接受的证书，则会出现此类错误。 - Bruno
我确实拥有客户端证书认证。密钥库包含客户端证书以及终端的自签名证书。因此，错误很可能是因为服务器不接受该证书？ - wuntee

更改默认的SSLContext不安全，因为它会影响整个进程。这会降低每个连接的安全设置，可能会对所有连接产生影响，并且我不确定它是否线程安全。

我建议将此类操作委托给每个请求的单独进程。

String content = new HttpsNoVerify.fetch(URL.create(myURL));

展示 com/example/HttpsNoVerify.java 的代码清单：

package com.example;

import org.apache.commons.io.IOUtils;

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import java.net.URL;

public class HttpsNoVerify {
    public static void main(String... args) throws Exception {
        URL url = new URL(args[0]);

        TrustManager[] trustAllCerts = new TrustManager[]{
            new X509TrustManager() {
                public java.security.cert.X509Certificate[] getAcceptedIssuers() {return null;}
                public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType){}
                public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType){}
            }
        };

        SSLContext sc = SSLContext.getInstance("SSL");
        sc.init(null, trustAllCerts, new java.security.SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());

        IOUtils.copy(url.openStream(), System.out);
    }

    public String fetch(URL url) throws Exception {
        return new SubProcess(HttpsNoVerify.class).run(url.toString());
    }
}

这里是 com/example/SubProcess.java 的清单：

package com.example;

import org.apache.commons.io.IOUtils;

import java.util.Arrays;

public class SubProcess {
    private final Class<?> classToRun;

    public SubProcess(Class<?> classToRun) {
        this.classToRun = classToRun;
    }

    public String run(String... args) throws Exception {
        ProcessBuilder processBuilder = new ProcessBuilder("java",
                "-Djava.library.path=" + System.getProperty("java.library.path"),
                "-classpath", System.getProperty("java.class.path"),
                classToRun.getCanonicalName());

        for (String arg : args) processBuilder.command().add(arg);

        processBuilder.redirectErrorStream();

        Process process = processBuilder.start();

        String output = IOUtils.toString(process.getInputStream());

        process.waitFor();

        if (process.exitValue() != 0)
            throw new IllegalStateException(
                    String.format("Running %s with %s failed", classToRun, Arrays.toString(args)));

        return output;
    }
}
你认为 'certificate_unknown' 异常是客户端的问题，有什么想法为什么会抛出这个异常？ - wuntee

@wuntee，我*强烈建议不要使用此TrustManager，因为它不会检查此客户端可能连接到的任何服务器证书的任何内容。相反，你可以使用我在答案中提出的变体，其中（a）只捕获CertificateExpiredException并且（b）在验证这是否是你想要的证书（来自chain[0]）后，可能忽略它。 - Bruno
@wuntee @Bruno的TrustManager绝对比我在这里使用的no-op更可取。我会将我的基于进程的方法与他的TrustManager结合起来，以获得整体解决方案。 - Alain O'Dea
我本来想加入更多的逻辑，最初只是试图让它工作...谢谢。 - wuntee
@Alain，编写jSSLutils及其包装器的动机之一是能够使用现有的信任管理器（最小配置），同时能够捕获和处理某些情况和异常。我认为这样做只是使它稍微更容易使用，因为可以访问我的示例中的“origManager”（这将是在此处没有特定设置的那个）。 - Bruno

我不知道有什么属性可以让您忽略默认的X509TrustManager上的远程证书的时间有效性检查，但如果您可以访问客户端代码，则可能可以配置一个不同的SSLContext，并在其中使用自己的X509TrustManager，从而可以捕获此异常。
如果您想使用类似于jSSLutils和其SSLContextFactory这样的东西，您可以编写以下包装器：
PKIXSSLContextFactory sslContextFactory = new PKIXSSLContextFactory();
sslContextFactory.setTrustManagerWrapper(new X509TrustManagerWrapper() {
    @Override
    public X509TrustManager wrapTrustManager(final X509TrustManager origManager) {
        return new X509TrustManager() { 
            @Override
            public X509Certificate[] getAcceptedIssuers() {
                return origManager.getAcceptedIssuers();
            }

            @Override
            public void checkServerTrusted(X509Certificate[] chain,
                                                   String authType)
                    throws CertificateException {
                try {
                    origManager.checkServerTrusted(chain, authType);
                } catch (CertificateExpiredException e) {
                    // TODO log or do something else to rethrow
                                    // the exception if chain[0] isn't the certificate
                                    // for which you want to make this special case.
                }
            }

            @Override
            public void checkClientTrusted(X509Certificate[] chain,
                                                   String authType)
                    throws CertificateException {
                origManager.checkClientTrusted(chain, authType);
            }
        };
    }
});
SSLContext sslContext = sslContextFactory.buildSSLContext();

利用这个 SSLContext 真正取决于你的应用中使用 SSL 的情况。在最坏的情况下，你可以使用 Java 6 及以上版本的 SSLContext.setDefault(sslContext) 全局配置它。否则，一些库将允许你配置一个 SSLContext。
