[[_setting_up_ssl]] === Setting up HTTPS/SSL WARNING: {project_name} is not set up by default to handle SSL/HTTPS. It is highly recommended that you either enable SSL on the {project_name} server itself or on a reverse proxy in front of the {project_name} server. This default behavior is defined by the SSL/HTTPS mode of each {project_name} realm. This is discussed in more detail in the link:{adminguide_link}[{adminguide_name}], but let's give some context and a brief overview of these modes. external requests:: {project_name} can run out of the box without SSL so long as you stick to private IP addresses like `localhost`, `127.0.0.1`, `10.0.x.x`, `192.168.x.x`, and `172.16.x.x`. If you don't have SSL/HTTPS configured on the server or you try to access {project_name} over HTTP from a non-private IP adress you will get an error. none:: {project_name} does not require SSL. This should really only be used in development when you are playing around with things. all requests:: {project_name} requires SSL for all IP addresses. The SSL mode for each realm can be configured in the {project_name} admin console. ==== Enabling SSL/HTTPS for the {project_name} Server If you are not using a reverse proxy or load balancer to handle HTTPS traffic for you, you'll need to enable HTTPS for the {project_name} server. This involves . Obtaining or generating a keystore that contains the private key and certificate for SSL/HTTP traffic . Configuring the {project_name} server to use this keypair and certificate. ===== Creating the Certificate and Java Keystore In order to allow HTTPS connections, you need to obtain a self signed or third-party signed certificate and import it into a Java keystore before you can enable HTTPS in the web container you are deploying the {project_name} Server to. ====== Self Signed Certificate In development, you will probably not have a third party signed certificate available to test a {project_name} deployment so you'll need to generate a self-signed one using the `keytool` utility that comes with the Java JDK. [source] ---- $ keytool -genkey -alias localhost -keyalg RSA -keystore keycloak.jks -validity 10950 Enter keystore password: secret Re-enter new password: secret What is your first and last name? [Unknown]: localhost What is the name of your organizational unit? [Unknown]: Keycloak What is the name of your organization? [Unknown]: Red Hat What is the name of your City or Locality? [Unknown]: Westford What is the name of your State or Province? [Unknown]: MA What is the two-letter country code for this unit? [Unknown]: US Is CN=localhost, OU=Keycloak, O=Test, L=Westford, ST=MA, C=US correct? [no]: yes ---- You should answer `What is your first and last name ?` question with the DNS name of the machine you're installing the server on. For testing purposes, `localhost` should be used. After executing this command, the `keycloak.jks` file will be generated in the same directory as you executed the `keytool` command in. If you want a third-party signed certificate, but don't have one, you can obtain one for free at http://www.cacert.org[cacert.org]. You'll have to do a little set up first before doing this though. The first thing to do is generate a Certificate Request: [source] ---- $ keytool -certreq -alias yourdomain -keystore keycloak.jks > keycloak.careq ---- Where `yourdomain` is a DNS name for which this certificate is generated for. Keytool generates the request: [source] ---- -----BEGIN NEW CERTIFICATE REQUEST----- MIIC2jCCAcICAQAwZTELMAkGA1UEBhMCVVMxCzAJBgNVBAgTAk1BMREwDwYDVQQHEwhXZXN0Zm9y ZDEQMA4GA1UEChMHUmVkIEhhdDEQMA4GA1UECxMHUmVkIEhhdDESMBAGA1UEAxMJbG9jYWxob3N0 MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAr7kck2TaavlEOGbcpi9c0rncY4HhdzmY Ax2nZfq1eZEaIPqI5aTxwQZzzLDK9qbeAd8Ji79HzSqnRDxNYaZu7mAYhFKHgixsolE3o5Yfzbw1 29RvyeUVe+WZxv5oo9wolVVpdSINIMEL2LaFhtX/c1dqiqYVpfnvFshZQaIg2nL8juzZcBjj4as H98gIS7khql/dkZKsw9NLvyxgJvp7PaXurX29fNf3ihG+oFrL22oFyV54BWWxXCKU/GPn61EGZGw Ft2qSIGLdctpMD1aJR2bcnlhEjZKDksjQZoQ5YMXaAGkcYkG6QkgrocDE2YXDbi7GIdf9MegVJ35 2DQMpwIDAQABoDAwLgYJKoZIhvcNAQkOMSEwHzAdBgNVHQ4EFgQUQwlZJBA+fjiDdiVzaO9vrE/i n2swDQYJKoZIhvcNAQELBQADggEBAC5FRvMkhal3q86tHPBYWBuTtmcSjs4qUm6V6f63frhveWHf PzRrI1xH272XUIeBk0gtzWo0nNZnf0mMCtUBbHhhDcG82xolikfqibZijoQZCiGiedVjHJFtniDQ 9bMDUOXEMQ7gHZg5q6mJfNG9MbMpQaUVEEFvfGEQQxbiFK7hRWU8S23/d80e8nExgQxdJWJ6vd0X MzzFK6j4Dj55bJVuM7GFmfdNC52pNOD5vYe47Aqh8oajHX9XTycVtPXl45rrWAH33ftbrS8SrZ2S vqIFQeuLL3BaHwpl3t7j2lMWcK1p80laAxEASib/fAwrRHpLHBXRcq6uALUOZl4Alt8= -----END NEW CERTIFICATE REQUEST----- ---- Send this ca request to your CA. The CA will issue you a signed certificate and send it to you. Before you import your new cert, you must obtain and import the root certificate of the CA. You can download the cert from CA (ie.: root.crt) and import as follows: [source] ---- $ keytool -import -keystore keycloak.jks -file root.crt -alias root ---- Last step is to import your new CA generated certificate to your keystore: [source] ---- $ keytool -import -alias yourdomain -keystore keycloak.jks -file your-certificate.cer ---- ===== Configure {project_name} to Use the Keystore Now that you have a Java keystore with the appropriate certificates, you need to configure your {project_name} installation to use it. First, you must edit the _standalone.xml_, _standalone-ha.xml_, or _host.xml_ file to use the keystore and enable HTTPS. You may then either move the keystore file to the _configuration/_ directory of your deployment or the file in a location you choose and provide an absolute path to it. If you are using absolute paths, remove the optional `relative-to` parameter from your configuration (See <<_operating-mode, operating mode>>). Add the new `security-realm` element using the CLI: [source] ---- $ /core-service=management/security-realm=UndertowRealm:add() $ /core-service=management/security-realm=UndertowRealm/server-identity=ssl:add(keystore-path=keycloak.jks, keystore-relative-to=jboss.server.config.dir, keystore-password=secret) ---- If using domain mode, the commands should be executed in every host using the `/host=/` prefix (in order to create the `security-realm` in all of them), like this, which you would repeat for each host: [source] ---- $ /host=/core-service=management/security-realm=UndertowRealm/server-identity=ssl:add(keystore-path=keycloak.jks, keystore-relative-to=jboss.server.config.dir, keystore-password=secret) ---- In the standalone or host configuration file, the `security-realms` element should look like this: [source,xml] ---- ---- Next, in the standalone or each domain configuration file, search for any instances of `security-realm`. Modify the `https-listener` to use the created realm: [source] ---- $ /subsystem=undertow/server=default-server/https-listener=https:write-attribute(name=security-realm, value=UndertowRealm) ---- If using domain mode, prefix the command with the profile that is being used with: `/profile=/`. The resulting element, `server name="default-server"`, which is a child element of `subsystem xmlns="{subsystem_undertow_xml_urn}"`, should contain the following stanza: [source,xml,subs="attributes+"] ---- ... ----
