1. Overview

When it comes to SSL connections, we should be using TLSv1.2. Indeed, it's the default SSL protocol for Java 8.

If we are using Java 1.7.095 or later, we can add the jdk.tls.client.protocols property as a java command-line argument to support TLSv1.2: java -Djdk.tls.client.protocols=TLSv1.2 But Java 1.7.095 is available only to the customers who purchased support from Oracle. So, we'll review other options below to.

And while Java 7 supports TLSv1.2, the default is TLS v1.0, which is too weak these days.

In this tutorial, we'll discuss various options to configure Java 7 to use TLSv1.2.

2. Using Java VM Arguments

If we are using Java 1.7.0_95 or later, we can add the jdk.tls.client.protocols property as a java command-line argument to support TLSv1.2:

But Java 1.7.0_95 is available only to the customers who purchased support from Oracle. So, we'll review other options below to enable TLSv1.2 on Java 7.

3. Using SSLSocket

In this first example, we'll enable TLSv1.2 using SSLSocketFactory.

First, we can create a default SSLSocketFactory object by calling the SSLSocketFactory#getDefault factory method.

Then, we simply pass our host and port to SSLSocket#createSocket:

The default SSLSocket created above doesn't have any SSL protocols associated with it. We can associate the SSL protocols to our SSLSocket in a couple of ways.

In the first approach, we can pass an array of supported SSL protocols to the setEnabledProtocols method on our SSLSocket instance:

Alternatively, we can use SSLParameters, using the same array:

4. Using SSLContext

Setting the SSLSocket directly changes only the one connection. We can use SSLContext to change the way we create the SSLSocketFactory.

So, instead of using SSLSocketFactory#getInstance, let's do SSLContext#getInstance, giving it “TLSv1.2” as a parameter.We can just get our SSLSocketFactory from that now:

As a quick side note, always remember to use SecureRandom when working with SSL.

5. Using HttpsURLConnection

Of course, we aren't always creating sockets directly. Oftentimes, we are at the application protocol level.

So, finally, let's see how to enable TLSv1.2 on HttpsURLConnection.

First, we'll need an instance of URL. Let's imagine that we are connecting to https://example.org:

Java 1.79

Now, we can set up our SSLContext as before:

Then, our last steps are to create the connection and supply it with an SSLSocketFactory:

6. Conclusion

In this quick article, we showed a few ways to enable TLSv1.2 on Java 7.

The code samples used in this article are available over on GitHub.

Java is a computer programming language that is concurrent, class-based and object-oriented. It was originally developed by James Gosling at Sun Microsystems. Java applications are compiled to bytecode (class file) that can run on any Java virtual machine (JVM) regardless of computer architecture.

Java is currently owned by the Oracle Corporation which acquired Sun Microsystems in 2010. Following tutorial will show you how to setup and configure Java 1.7 on Windows so you can develop and run Java code.

Check following posts if you are looking to download and install JDK 1.5, JDK 1.6, JDK 1.8, JDK 1.9 or JDK 1.10.

Java can be obtained from the Oracle Java download page. There are a number of different Java packages available, for this tutorial we will be installing Java Standard Edition (SE) on Windows.

In order to be able to compile Java code, we need the Java Development Kit (JDK) package that comes with a Java compiler. The JDK package also comes with a Java runtime environment (JRE) that is needed to run compiled Java code.

As we are installing an older Java version, you need to scroll all the way down to the bottom of the Oracle Java download page and click on the Download button in the Java Archive section. Then look for the Java SE 7 link and after clicking on it, select the correct operating system under Java SE Development Kit 7u80.

Here is the direct link to download the jdk 1.7.0_80 installer for Windows 32 or 64 bit.

Accept the License Agreement and pick the correct download for your operating system. In this example, we will use the Windows 64 bit version.

Sign in using your Oracle account (or create a new one) and the download should start. Once the download is complete, locate the jdk-7u80-windows-x64.exe file and double-click to run the installer.

Click Next and on the following screen optionally change the installation location by clicking on the Change... button. In this example the install location was changed to 'C:Javajdk1.7.0_80'. From now on we will refer to this directory as: [java_install_dir].

Next, the installer will present the installation location of the public JRE. We will skip this part of the installer as the JDK installed in the previous step comes with a private JRE that can run developed code. Just press Cancel and confirm by clicking Yes in the popup window.

Click Next and then Close to finish installing Java.

In order for Java applications to be able to run we need to setup a 'JAVA_HOME' environment variable that will point to the Java installation directory. In addition, if we want to run Java commands from a command prompt we need to setup the 'PATH' environment variable to contain the Java bin directory.

When using Windows the above parameters can be configured on the Environment Variables panel. Click on the Windows Start button and enter “env” without quotes as shown below.

Environment variables can be set at account level or at system level. For this example click on Edit environment variables for your account and following panel should appear.

Click on the New button and enter “JAVA_HOME” as variable name and the [java_install_dir] as variable value. In this tutorial the installation directory is 'C:Javajdk1.7.0_80'. Click OK to to save.

Click on the New button and enter “PATH” as variable name and “%JAVA_HOME%bin” as variable value. Click OK to save.

Note that in case a 'PATH' variable is already present you can add “;%JAVA_HOME%bin” at the end of the variable value.

Java 1.7 Tls 1.2

The result should be as shown below. Click OK to close the environment variables panel.

In order to test the above configuration, open a command prompt by clicking on the Windows Start button and typing “cmd” followed by pressing ENTER. A new command prompt should open in which the following command can be entered to verify the installed Java version:

The result should be as shown below.

This concludes the setting up and configuring JDK 1.7 on Windows.
