Question

在TLSv1.2上将PC连接到Android Server（5.0.2）时出现了另一个TLS问题。

当尝试连接到PC的Android应用程序时，一切都很好。

JCE安装在PC上。

以下是调试：

如何解决此问题？

服务器

    System.setProperty("https.protocols", "TLSv1.2");
    System.setProperty("jdk.tls.client.protocols", "TLSv1.2");

    KeyManagerFactory keyManagerFactory;
    keyManagerFactory = KeyManagerFactory.getInstance("PKIX");
    keyManagerFactory.init(keyStore, keyPairPassword);

    TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance("PKIX");
    trustManagerFactory.init(trustStore);

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

    SSLServerSocketFactory sslServerSocketFactory = sslContext.getServerSocketFactory();

    SSLServerSocket sslServerSocket
            = (SSLServerSocket) sslServerSocketFactory.createServerSocket(port);
    sslServerSocket.setEnabledCipherSuites(new String[]{"TLS_DHE_RSA_WITH_AES_128_CBC_SHA256",
    "TLS_DHE_RSA_WITH_AES_128_GCM_SHA256",
    "TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256",
    "TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256"});
    sslServerSocket.setNeedClientAuth(true);

客户端

    System.setProperty("https.protocols", "TLSv1.2");
    System.setProperty("jdk.tls.client.protocols", "TLSv1.2");
    KeyStore keyStore = getKeyStore();

    KeyManagerFactory keyManagerFactory;
    keyManagerFactory = KeyManagerFactory.getInstance("PKIX");
    keyManagerFactory.init(keyStore, getPassword());

    KeyStore trustStore = getTrustStore();
    TrustManagerFactory trustManagerFactory;
    trustManagerFactory = TrustManagerFactory.getInstance("PKIX");
    trustManagerFactory.init(trustStore);

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

    SSLSocket socket = (SSLSocket) sslContext.getSocketFactory().createSocket(
    ipAddress, port);
    socket.setTcpNoDelay(true);
    socket.setKeepAlive(false);
    socket.setNeedClientAuth(true);
    socket.startHandshake();

Answer 1

如所示 https://blogs.oracle.com/java-platform-group/entry/diagnosing_tls_ssl_and_https 当客户端和服务器没有共同的算法时会发生此错误。

请注意，这有点误导：客户端不仅要有一个共同的算法，还要有一个椭圆曲线（如果使用椭圆曲线）。

ClientHello列出

中支持的曲线

Extension elliptic_curves, curve names: ...

但是，如果对应方（服务器）需要您（客户端）不支持的曲线，例如brainpoolP256r1，您将收到此错误。

要检查，请安装wireshark捕获不同的ClientHello并检查差异。此外，您可以使用openSSL检查服务器以获取支持的曲线。例如，对于openSSL支持的brainpoolP256r1（但不支持Java，甚至是带有JCE Unlimited Strength的JDK 1.8），你可以做到

openssl s_client -connect YOUR_URL[:PORT] -tls1_2

如果连接成功，您将输出包括

之类的内容

No client certificate CA names sent
Client Certificate Types: RSA sign, DSA sign, ECDSA sign
Requested Signature Algorithms: RSA+SHA512:DSA+SHA512:ECDSA...
Shared Requested Signature Algorithms: RSA+SHA512:DSA+SHA51...
Peer signing digest: SHA512
Server Temp Key: ECDH, brainpoolP256r1, 256 bits
---
SSL handshake has read 2511 bytes and written 455 bytes
---
New, TLSv1/SSLv3, Cipher is ECDHE-ECDSA-AES256-GCM-SHA384

其中曲线由

表示

Server Temp Key: ...

BouncyCastle支持标准Java不支持的众多算法。尝试使用BouncyCastle建立TLS连接。
