helloworld-mutual-ssl: {productName} Mutual SSL(two-way) Configuration Example

The helloworld-mutual-ssl quickstart is a basic example that demonstrates mutual SSL configuration in {productName}

What is it?

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 {productName} to enable TLS/SSL configuration for the new {productName} 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.

Set Up Client and Server Keystores Using Java Keytool

  1. Open a terminal and navigate to the {productName} server configuration directory:

    $ cd {jbossHomeName}/standalone/configuration/
  2. Create a certificate for your server using the following command:

    $>keytool -genkey -keyalg RSA -keystore server.keystore -storepass secret -keypass secret -validity 365
    
    What is your first and last name?
       [Unknown]:  localhost
    What is the name of your organizational unit?
       [Unknown]:  wildfly
    What is the name of your organization?
       [Unknown]:  jboss
    What is the name of your City or Locality?
       [Unknown]:  Raleigh
    What is the name of your State or Province?
       [Unknown]:  Carolina
    What is the two-letter country code for this unit?
       [Unknown]:  US
    Is CN=localhost, OU=wildfly, O=jboss, L=Raleigh, ST=Carolina, C=US correct?
       [no]:  yes
  3. Create the client certificate, which is used to authenticate against the server when accessing a resource through SSL.

    $>keytool -genkey -keystore client.keystore -storepass secret -validity 365 -keyalg RSA -keysize 2048 -storetype pkcs12
    
    What is your first and last name?
        [Unknown]:  quickstartUser
    What is the name of your organizational unit?
        [Unknown]:  Sales
    What is the name of your organization?
        [Unknown]:  My Company
    What is the name of your City or Locality?
        [Unknown]:  Sao Paulo
    What is the name of your State or Province?
        [Unknown]:  Sao Paulo
    What is the two-letter country code for this unit?
        [Unknown]:  BR
    Is CN=quickstartUser, OU=Sales, O=My Company, L=Sao Paulo, ST=Sao Paulo, C=BR correct?
        [no]:  yes
  4. Export the client certificate and create a truststore by importing this certificate:

    $>keytool -exportcert -keystore client.keystore  -storetype pkcs12 -storepass secret -keypass secret -file client.crt
    $>keytool -import -file client.crt -alias quickstartUser -keystore client.truststore -storepass secret
    
    Owner: CN=quickstartUser, OU=Sales, O=My Company, L=Sao Paulo, ST=Sao Paulo, C=BR
    Issuer: CN=quickstartUser, OU=Sales, O=My Company, L=Sao Paulo, ST=Sao Paulo, C=BR

    Valid from: Mon Jul 24 16:14:03 BRT 2017 until: Tue Jul 24 16:14:03 BRT 2018

    ]
    ]
    
    Trust this certificate? [no]:  yes
    Certificate was added to keystore
  5. Export client certificate to pkcs12 format

    $>keytool -importkeystore -srckeystore client.keystore -srcstorepass secret -destkeystore clientCert.p12 -srcstoretype PKCS12 -deststoretype PKCS12 -deststorepass secret
  6. The certificates and keystores are now properly configured.

Configure the Server

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.

  1. Before you begin, make sure you do the following:

  2. Review the configure-ssl.cli file in the root of this quickstart directory. Comments in the script describe the purpose of each block of commands.

  3. Open a new terminal, navigate to the root directory of this quickstart, and run the following command, replacing {jbossHomeName} with the path to your server:

    $ {jbossHomeName}/bin/jboss-cli.sh --connect --file=configure-ssl.cli
    Note
    For Windows, use the {jbossHomeName}\bin\jboss-cli.bat script.

    You should see the following result when you run the script:

    The batch executed successfully
    process-state: reload-required
  4. Stop the {productName} server.

Review the Modified Server Configuration

After stopping the server, open the {jbossHomeName}/standalone/configuration/standalone.xml file and review the changes.

  1. The following keystore elements 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>
  2. 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>
  3. The following trust-manager was added to the elytron subsystem:

    <trust-managers>
        <trust-manager name="qsTrustManager" key-store="qsTrustStore"/>
    </trust-managers>
  4. 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>
  5. 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"/>

Test the Server SSL Configuration

To test the SSL configuration, access: https://localhost:8443

If it is configured correctly, you should be asked to trust the server certificate.
