在 Android 4.1 上改造 2 TLS 1.1

Question

我尝试使用此代码设置支持的 TLS 版本：

ConnectionSpec spec = new ConnectionSpec.Builder(ConnectionSpec.MODERN_TLS)
            .tlsVersions(TlsVersion.TLS_1_3, TlsVersion.TLS_1_2, TlsVersion.TLS_1_1)
            .cipherSuites(
                    CipherSuite.TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384,
                    CipherSuite.TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384,
                    CipherSuite.TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256,
                    CipherSuite.TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256,
                    CipherSuite.TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,
                    CipherSuite.TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,
                    CipherSuite.TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384,
                    CipherSuite.TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384,
                    CipherSuite.TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256,
                    CipherSuite.TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,
                    CipherSuite.TLS_DHE_RSA_WITH_AES_128_GCM_SHA256)
            .build();

    builder.connectionSpecs(Collections.singletonList(spec));

我使用这些库：

compile 'com.squareup.okhttp3:okhttp:3.5.0'
compile 'com.squareup.retrofit2:retrofit:2.1.0'

但我得到了这个例外：

HTTP 失败：java.net.UnknownServiceException：无法找到可接受的协议。 isFallback =假，模式= [ConnectionSpec的（密码组= [TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384，TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384，TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256，TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256，TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256，TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256，TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384，TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384，TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256，TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256，TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256，TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256，TLS_DHE_RSA_WITH_AES_128_GCM_SHA256]，tlsVersions = [TLS_1_3，TLS_1_2，TLS_1_1]，supportsTlsExtensions =true)], 支持的协议=[SSLv3, TLSv1]

你能帮我吗，如何在 android 4.1 上使用 TLS 1.1 或 TLS 1.2？

我试图深入研究 SSLSocketfactory 并找到 fkrauthan 的 TLSSocketFactory。按原样投入到我的项目中。

将不同来源的东西放在一起并创建“MyTrustManager”。

public class MyTrustManager {
public X509TrustManager trustManagerForCertificates(InputStream in) throws GeneralSecurityException {
    CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509");
    Collection<? extends Certificate> certificates = certificateFactory.generateCertificates(in);
    if (certificates.isEmpty()) {
        throw new IllegalArgumentException("expected non-empty set of trusted certificates");
    }

    char[] password = "password".toCharArray(); // Any password will work.
    KeyStore keyStore = newEmptyKeyStore(password);
    int index = 0;
    for (Certificate certificate : certificates) {
        String certificateAlias = Integer.toString(index++);
        keyStore.setCertificateEntry(certificateAlias, certificate);
    }

    // Use it to build an X509 trust manager.
    KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance(
            KeyManagerFactory.getDefaultAlgorithm());
    keyManagerFactory.init(keyStore, password);
    TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(
            TrustManagerFactory.getDefaultAlgorithm());
    trustManagerFactory.init(keyStore);
    TrustManager[] trustManagers = trustManagerFactory.getTrustManagers();
    if (trustManagers.length != 1 || !(trustManagers[0] instanceof X509TrustManager)) {
        throw new IllegalStateException("Unexpected default trust managers:"
                + Arrays.toString(trustManagers));
    }
    return (X509TrustManager) trustManagers[0];
}

private KeyStore newEmptyKeyStore(char[] password) throws GeneralSecurityException {
    try {
        KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
        InputStream in = null; // By convention, 'null' creates an empty key store.
        keyStore.load(in, password);
        return keyStore;
    } catch (IOException e) {
        throw new AssertionError(e);
    }
}

public InputStream trustedCertificatesInputStream() {
    String comodoRsaCertificationAuthority = ""

}

设置 MyTrustManger

OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
setSSLSocketFactory(httpClient);

这里是setSSLSocketFactory

private static void setSSLSocketFactory(OkHttpClient.Builder httpClient) {
    try {
        MyTrustManager myTrustManager = new MyTrustManager();
        TrustManager trustManager = myTrustManager.trustManagerForCertificates(
                myTrustManager.trustedCertificatesInputStream());
        httpClient.sslSocketFactory(new TLSSocketFactory(), (X509TrustManager) trustManager);
    } catch (GeneralSecurityException e) {
        e.printStackTrace();
    }
}
