HttpURLConnection has examples showing how to deal with requestĪnd response headers, posting content, managing cookies, using proxies, caching responses,Īnd more. If you want to tailor the HTTP request, you can cast toĪn HttpURLConnection. InputStream in = urlConnection.getInputStream() ĬopyInputStreamToOutputStream(in, System.out) URLConnection urlConnection = url.openConnection() Val inputStream: InputStream = urlConnection.getInputStream()ĬopyInputStreamToOutputStream(inputStream, System.out) Val urlConnection: URLConnection = url.openConnection() You can see that the certificate was issued for servers matching *. byĬertificate issued by a well-known CA, you can make a secure request as shown in the following code: Subject= /serialNumber=sOrr2rKpMVP70Z6E9BT5reY008SJEdYv/C=US/O=*./OU=GT03314600/OU=See (c)11/OU=Domain Control Validated - RapidSSL(R)/ CN=*. issuer= /C=US/O=GeoTrust, Inc./CN= RapidSSL CA $ openssl s_client -connect :443 | openssl x509 -noout -subject -issuer The command asks for the subject, which contains the server name information, The output of openssl s_client to openssl x509, which formats informationĪbout certificates according to the X.509 standard. Specifies port 443 because that is the default for HTTPS. Tool's s_client command looks at Wikipedia's server certificate information. In the snippet from a command line that follows, the openssl To address this, the certificate issued by the CA identifies the serverĮither with a specific name, such as, or a wildcarded set of Because the CA issuesĬertificates for many servers, you still need some way to make sure you are talking to the However, while solving some problems, using CAs introduces another. TheĬlient can then verify that the server has a certificate issued by a CA known to the platform. The server certificate using its private key. Similar to a server, a CA has a certificate and a private key. In each release and don't change from device to device. The host platform generally contains a list of well-known CAs that it trusts.Īs of Android 8.0 (API level 26), Android contained over 100 CAs that are updated To address these downsides, servers are typically configured with certificatesįrom well-known issuers called Certificate Authorities (CAs). ThisĪpproach also has issues if the app has to talk to arbitrary servers such as a web browser or Isn't under the app developer's control, for example if it is a third-party web service. This is especially problematic if the server Is essentially a server configuration change.

Unfortunately, the client app then has to be updated due to what

Upgrade to stronger keys over time ('key rotation'), which replaces the public key in theĬertificate with a new one. There are several downsides to this simple approach. Have a set of one or more certificates it trusts. One way to solve this problem is to have the client Matches the public key of the certificate. However, anyone can generate their own certificate and private key, so a simple handshakeĭoesn't prove anything about the server other than that the server knows the private key that As part of the handshake between a TLS clientĪnd server, the server proves it has the private key by signing its certificate with public-key cryptography. In a typical TLS usage scenario, a server is configured with a certificate containing a To your app, this article highlights the common pitfalls when using secure network protocols andĪddresses some larger concerns about using Public-Key Infrastructure (PKI). Incorrectly might let malicious entities intercept an app's data over the network. The Secure Sockets Layer (SSL)-now technically known as Transport Layer SecurityĬommon building block for encrypted communications between clients and servers.
