Summary: The helloworld-mutual-ssl
quickstart is a basic example that demonstrates mutual SSL configuration in WildFly
Target Product: WildFly
Source: https://github.com/wildfly/quickstart/
Mutual SSL provides the same security as SSL, with the addition of authentication and non-repudiation of the client authentication, using digital signatures. When mutual authentication is used, the server requests the client to provide a certificate in addition to the server certificate issued to the client. Mutual authentication requires an extra round trip each time for client certificate exchange. In addition, the client must buy and maintain a digital certificate.
This quickstart shows how to configure WildFly to enable TLS/SSL configuration for the new WildFly undertow
subsystem and enable mutual (two-way) SSL authentication.
Before you run this example, you must create certificates and configure the server to use two-way SSL.
The applications these projects produce are designed to be run on WildFly Application Server 11 or later.
All you need to build these projects is Java 8.0 (Java SDK 1.8) or later and Maven 3.3.1 or later. See Configure Maven for WildFly 11 to make sure you are configured correctly for testing the quickstarts.
To run these quickstarts with the provided build scripts, you need the WildFly distribution ZIP. For information on how to install and run JBoss, see the WildFly Application Server Documentation Getting Started Guide located on the Customer Portal.
You can also use JBoss Developer Studio or Eclipse to run the quickstarts.
In the following instructions, replace WILDFLY_HOME
with the actual path to your WildFly installation. The installation path is described in detail here: Use of WILDFLY_HOME and JBOSS_HOME Variables.

Export client certificate to pkcs12 format

The certificates and keystores are now properly configured.
These steps assume you are running the server in standalone mode and using the default standalone.xml
supplied with the distribution.
You configure the SSL context by running JBoss CLI commands. For your convenience, this quickstart batches the commands into a configure-ssl.cli
script provided in the root directory of this quickstart.
Before you begin, back up your server configuration file
WILDFLY_HOME/standalone/configuration/standalone.xml
Start the WildFly server by typing the following:
For Linux: WILDFLY_HOME/bin/standalone.sh
For Windows: WILDFLY_HOME\bin\standalone.bat
configure-ssl.cli
file in the root of this quickstart directory. Comments in the script describe the purpose of each block of commands.Open a new command prompt, navigate to the root directory of this quickstart, and run the following command, replacing WILDFLY_HOME with the path to your server:
For Linux: WILDFLY_HOME/bin/jboss-cli.sh --connect --file=configure-ssl.cli
For Windows: WILDFLY_HOME\bin\jboss-cli.bat --connect --file=configure-ssl.cli
You should see the following result when you run the script:
The batch executed successfully
process-state: reload-required
Stop the WildFly server.
After stopping the server, open the WILDFLY_HOME/standalone/configuration/standalone.xml
file and review the changes.
The following key-store
s were added to the elytron
subsystem:
<key-store name="qsKeyStore">
<credential-reference clear-text="secret"/>
<implementation type="JKS"/>
<file path="server.keystore" relative-to="jboss.server.config.dir"/>
</key-store>
<key-store name="qsTrustStore">
<credential-reference clear-text="secret"/>
<implementation type="JKS"/>
<file path="client.truststore" relative-to="jboss.server.config.dir"/>
</key-store>
The following key-manager
was added to the elytron
subsystem:
<key-managers>
<key-manager name="qsKeyManager" key-store="qsKeyStore">
<credential-reference clear-text="secret"/>
</key-manager>
</key-managers>
The following trust-manager
was added to the elytron
subsystem:
<trust-managers>
<trust-manager name="qsTrustManager" key-store="qsTrustStore"/>
</trust-managers>
The following ssl-context
was added to the elytron
subsystem:
<server-ssl-contexts>
<server-ssl-context name="qsSSLContext" protocols="TLSv1.2" need-client-auth="true" key-manager="qsKeyManager" trust-manager="qsTrustManager"/>
</server-ssl-contexts>
The https-listener
in the undertow
subsystem was changed to reference the qsSSLContext
ssl-context
:
<https-listener name="https" socket-binding="https" ssl-context="qsSSLContext" enable-http2="true"/>
To test the SSL configuration, access: https://localhost:8443
If it is configured correctly, you should be asked to trust the server certificate.
Before you access the application, you must import the clientCert.p12, which holds the client certificate, into your browser.
clientCert.p12
file. You will be prompted to enter the password: secret
.clientCert.p12
file. You will be prompted to enter the password: secret
.For Linux: /bin/standalone.sh
For Windows: bin\standalone.bat
NOTE: The following build command assumes you have configured your Maven user settings. If you have not, you must include Maven setting arguments on the command line. See Build and Deploy the Quickstarts for complete instructions and additional options.
mvn clean package wildfly:deploy
This will deploy target/helloworld-mutual-ssl.war
to the running instance of the server.
The application will be running at the following URL: https://localhost:8443/helloworld-mutual-ssl/HelloWorld.
A page displaying the client certificate should be visible:

You can restore the original server configuration by running the restore-configuration.cli
script provided in the root directory of this quickstart or by manually restoring the back-up copy the configuration file.
For Linux: WILDFLY_HOME/bin/standalone.sh
For Windows: WILDFLY_HOME\bin\standalone.bat
For Linux: WILDFLY_HOME/bin/jboss-cli.sh --connect --file=restore-configuration.cli
For Windows: WILDFLY_HOME\bin\jboss-cli.bat --connect --file=restore-configuration.cli
This script reverts the changes made to the undertow
subsystem and it also removes the ssl-context
, key-manager
, trust-manager
and key-store
s from the elytron
subsystem. You should see the following result when you run the script:
