是否可以在 JDK 1.7 上使用 GCM 和 BC？

Question

我正在尝试使用任何 AES GCM 变体进行 TLS 连接，根据我在文档中的理解，这应该是可能的，但我收到此错误：

Caused by: javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure
    at sun.security.ssl.Alerts.getSSLException(Alerts.java:192)
    at sun.security.ssl.Alerts.getSSLException(Alerts.java:154)
    at sun.security.ssl.SSLSocketImpl.recvAlert(SSLSocketImpl.java:1989)
    at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:1096)
    at sun.security.ssl.SSLSocketImpl.performInitialHandshake(SSLSocketImpl.java:1342)
    at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1369)

问题是我尝试连接的服务器只接受这些密码：

TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
TLS_RSA_WITH_AES_256_GCM_SHA384
TLS_RSA_WITH_AES_128_GCM_SHA256

我无法在此处发布我尝试连接的服务器，但我尝试在 github 存储库上复制该问题。我找不到只接受这些密码套件的服务器，这就是为什么我的 repo 因另一个错误而失败。

git clone https://github.com/andreicristianpetcu/gcm_with_bc_onjdk17
cd gcm_with_bc_onjdk17
JAVA_HOME="/usr/lib/jvm/java-7-openjdk-amd64/jre" mvn clean install

基本上这是来自 GitHub 的代码

    package com.github.gcm_with_bc_onjdk17;

    import org.apache.http.client.methods.CloseableHttpResponse;
    import org.apache.http.client.methods.HttpGet;
    import org.apache.http.conn.ssl.NoopHostnameVerifier;
    import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
    import org.apache.http.impl.client.CloseableHttpClient;
    import org.apache.http.impl.client.HttpClients;
    import org.apache.http.ssl.SSLContexts;

    import javax.crypto.Cipher;
    import javax.crypto.NoSuchPaddingException;
    import javax.net.ssl.SSLContext;
    import java.io.IOException;
    import java.security.KeyManagementException;
    import java.security.NoSuchAlgorithmException;
    import java.security.NoSuchProviderException;
    import java.security.Security;

    public class GcmWithBouncyCasteleOnJDK17 {

        public SSLConnectionSocketFactory getSslConnectionSocketFactory() throws NoSuchAlgorithmException, NoSuchProviderException, NoSuchPaddingException, KeyManagementException, IOException {
            Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());
            Cipher cipher = Cipher.getInstance("AES/GCM/NoPadding", "BC");
            System.out.println(cipher);

            SSLContext sslContext = SSLContexts.custom()
                    .build();

            SSLConnectionSocketFactory sslConnectionSocketFactory = new SSLConnectionSocketFactory(sslContext, NoopHostnameVerifier.INSTANCE);

            CloseableHttpClient httpClient = HttpClients.custom()
                    .setSSLSocketFactory(sslConnectionSocketFactory)
                    .build();

            HttpGet out = new HttpGet("https://cloudflare.com/");
            CloseableHttpResponse execute = httpClient.execute(out);
            return sslConnectionSocketFactory;
        }

    }

谢谢

Answer 1

一位同事发现了这个问题:)这里是修复：

Security.removeProvider(BouncyCastleProvider.PROVIDER_NAME);
Security.removeProvider(BouncyCastleJsseProvider.PROVIDER_NAME);
Security.insertProviderAt(new BouncyCastleProvider(), 0);
Security.insertProviderAt(new BouncyCastleJsseProvider(), 1);

JDK7 似乎支持 TLS 1.2 但不支持 AES GCM 密码。由于加密提供程序是一个列表，JDK 提供程序以某种方式被选中，因为它支持 TLS 1.2，即使它不支持所需的密码。将 Bouncy Castle 在列表中稍微高一点就解决了这个问题。

我不知道为什么我的问题被否决了:(我不知道我违反了什么规则所以它被否决了，我什至提供了源代码。

无论如何......非常高兴我找到了修复，即使它在 Stack Overflow 之外。留给子孙后代吧。
