【问题描述】：
我正在开发一个需要通过 HTTPS 连接下载的 android 应用程序。但我得到了 SSLHandshakeException - 握手失败。
我所做的如下
首先，使用openssl获取服务器证书链
openssl s_client -connect www.coles.com.au:443
得到了
Certificate chain
0 s:/C=AU/ST=Victoria/L=Hawthorn East/O=Coles Supermarkets Australia Pty Ltd/OU=Web Team/CN=coles.com.au
i:/C=US/O=thawte, Inc./CN=thawte SSL CA - G2
1 s:/C=US/O=thawte, Inc./CN=thawte SSL CA - G2
i:/C=US/O=thawte, Inc./OU=Certification Services Division/OU=(c) 2006 thawte, Inc. - For authorized use only/CN=thawte Primary Root CA

No client certificate CA names sent
Peer signing digest: SHA1
然后去 thawte 网站(https://search.thawte.com/support/ssl-digital-certificates/index?page=content&id=SO26817&actp=RSS&viewlocale=en_US#links) 下载 CA 证书（告诉我是我做错了还是从错误的地方下载）是 thawte_SSL_CA_G2.cer
第三，我有下面的代码来连接
String url = "https://www.coles.com.au";
String strContent = "";
HttpURLConnection connection;
AssetManager assetManager = context.getAssets();
InputStream caInput = null;
try{
CertificateFactory cf = CertificateFactory.getInstance("X.509");
caInput = assetManager.open("thawte_SSL_CA_G2.cer");
Certificate ca = cf.generateCertificate(caInput);
String keyStoreType = KeyStore.getDefaultType();
KeyStore keyStore = KeyStore.getInstance(keyStoreType);
keyStore.load(null, null);
keyStore.setCertificateEntry("ca", ca);
String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
tmf.init(keyStore);
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, tmf.getTrustManagers(), null);
URL urlObj = new URL(url);
HttpsURLConnection urlConnection =
(HttpsURLConnection)urlObj.openConnection();
urlConnection.setSSLSocketFactory(context.getSocketFactory());
InputStream in = urlConnection.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
while(null != (strContent= reader.readLine())){
System.out.println(strContent);
}
}
catch (IOException e){
String exception = e.getMessage();
System.out.println(exception);
}
我用wireshark捕捉并观察下面发生的事情
-> Client Hello
<- Server Hello
<- Certificate
<- Server Key Exchange
-> Client Key Exchange, Change Cipher Spec, Hello Request, Hello Request
<- FIN
请帮助我了解握手失败的原因。
【问题讨论】：
-
相关，请使用以下
openssl s_client -connect www.coles.com.au:443 -tls1 -servername www.coles.com.au。这将为您提供 TLS 1.0（不是 SSLv3），并使用服务器名称指示 (SNI)。 -
@jww 通过使用您的命令，检索到相同的结果。我得到了正确的证书吗？
