• Certificate stores can be managed from the command line and using tools that provide a GUI for this purpose:
  • the Java keytool is available from the Java JRE or JDK,
  • the Keystore Explorer, which is an open source utility to graphically manage certificate stores.
• Starting from Java 9 the PKCS12 keystore type is default and is not required to be specified with keytool.
• The following sections assume a PKCS12 keystore/truststore format. For Unix OS the .p12 file extension frequently is used, for Windows OS the .pfx extension is preferably used. Both file extensions indicate the same PKCS12 format and can be used interchangeably.

...

• On the Agent server create the keystore using the keytool from your Java JRE or JDK. Alternatively import a private key and certificate that you received from your certificate authority:
  • For use with a third party utility create a keystore, e.g. https-keystore.p12, in PKCS12 format and import:
    • the Agent private key and certificate for Server Authentication
    • the Root CA certificate
    • Intermediate CA certificate(s)
  • For use with keytool create the keystore with the private key and certificate for Server Authentication from the command line. The examples below show one possible approach for certificate management. However, there are other ways to achieve similar results.

    • Example for the use of creating a private key and CA-signed certificate with a PKCS12 storekeystore:

      Code Block
      language bash title Example how to create and add a private key and CA-signed certificate to a PKCS12 keystore

    • Explanation:

      • The -dname option specifies the certificate issuer, therefore use your own set of CN, O, OU, DC that specify the issuer's Distinguished Name. The O setting is required for the issuer.
      • The -keypass option accepts the password that you will need later on to manage your private key.
      • The -keystore option specifies the location of the keystore file. The keystore file should be in reach of the Agent, it is recommended that you use the sub-folder private in the JS7_AGENT_CONFIG_DIR directory.
      • The -storepass option specifies the password for access to the keystore file.
      • The -storetype option is used to specify the PKCS12 or JKS keystore format.
  • With the keystore set up specify the relevant properties with the JS7_AGENT_CONFIG_DIR/private/private.conf configuration file:

    • Example

      Code Block
      language text title Example for private.conf file specifying the Agent keystore
      js7 { web { # keystore and truststore locations for https connections https { keystore { # Default: ${js7.config-directory}"/private/https-keystore.p12" file=${js7.config-directory}"/private/https-keystore.p12" key-password="jobscheduler" store-password="jobscheduler" } } } }

      
      

      Explanation:
      • js7.web.https.keystore.file is used for the path to the keystore.
      • js7.web.https.keystore.key-password is used for access to the private key.
      • js7.web.https.keystore.store-password is used for access to the keystore

...

• By default mutual authentication is in place.
  • The Controller is challenged by the Agent to present its Client Authentication certificate which is then verified by the Agent.
  • If a Controller cluster Cluster is used then connections from both Controller instances are authenticated by the Distinguished Name of the Controller instance's Client Authentication certificate.

• The JS7_AGENT_CONFIG_DIR/private/private.conf configuration file should include authentication details like this:

  Code Block
  title Example for private.conf file specifying Controller authentication
  js7 { auth { users { # Controller ID for connections by primary/standby Controller instance jobscheduler { distinguished-names=[ "DNQ=SOS CA, CN=apmacwinprimary_primarycontroller_client, OU=IT, O=SOS, L=Berlin, ST=Berlin, C=DE", "DNQ=SOS CA, CN=apmacwinsecondary_secondarycontroller_client, OU=IT, O=SOS, L=Berlin, ST=Berlin, C=DE" ] } } } }

  
  

  Explanation:
  • The jobscheduler user account is an example of a Controller ID that is specified during Controller installation.
  • The distinguished-names property allows the addition of a number of distinguished names as Distinguished Names as available from the subject of Client Authentication certificates that are used by Controller instances when connecting to the Agent.
    
    • Except for whitespace between attributes the precise sequence and values as available from the certificate's subject has to match this property value.

...

• To make an Agent use HTTPS, the relevant port setting has to be specified with the Agent's Instance Start Script.

  • For Unix the Instance Start Script is available from JS7_AGENT_HOME/bin/agent_<port>.sh:

    Code Block
    language xml title Example for HTTP and HTTPS port settings with Agent Instance Start Script for Unix
    # Sets the http port for the JS7 Agent. # Without this setting the default port 4445 is used. # If just a port is specified then the JS7 Agent listens to all # available network interfaces. This corresponds to 0.0.0.0:<port>. # Use the form <ip address or hostname>:<port> to indicate # a specific network interface the JS7 Agent should listen to. # The command line option --http-port beats the environment # variable JS7_AGENT_HTTP_PORT. JS7_AGENT_HTTP_PORT=localhost:4445 # In addition to the http port an https port for the # JS7 Agent can be specified. If just a port is specified # then the JS7 Agent listens to all available network interfaces. # This corresponds to using 0.0.0.0:<port>. # Use the form <ip address or hostname>:<port> to indicate # a specific network interface the JS7 Agent should listen to. # The command line option --https-port beats the environment # variable JS7_AGENT_HTTPS_PORT. JS7_AGENT_HTTPS_PORT=apmacwinagent.example.com:4445

  • For Windows the Instance Start Script is available from JS7_AGENT_HOME\bin\agent_<port>.cmd:

    Code Block
    language xml title Example for HTTP and HTTPS port settings with Agent Instance Start Script for Windows collapse true
    rem # Sets the http port for the JS7 Agent. rem # Without this setting the default port 4445 is used. rem # If just a port is specified then the JS7 Agent listens to all rem # available network interfaces. This corresponds to 0.0.0.0:<port>. rem # Use the form <ip address or hostname>:<port> to indicate rem # a specific network interface the JS7 Agent should listen to. rem # The command line option --http-port beats the environment rem # variable JS7_AGENT_HTTP_PORT. set JS7_AGENT_HTTP_PORT=localhost:4445 rem # In addition to the http port an https port for the rem # JS7 Agent can be specified. If just a port is specified rem # then the JS7 Agent listens to all available network interfaces. rem # This corresponds to using 0.0.0.0:<port>. rem # Use the form <ip address or hostname>:<port> to indicate rem # a specific network interface the JS7 Agent should listen to. rem # The command line option --https-port beats the environment rem # variable JS7_AGENT_HTTPS_PORT. set JS7_AGENT_HTTPS_PORT=apmacwinagent.example.com:4445

    
    

    Explanation:
    • The HTTP port is required but is limited to the localhost network interface with the localhost prefix.
    • The HTTPS port is specified with the hostname prefix that indicates the network interface.

• On the Controller server create the truststore using the keytool from your Java JRE or JDK or a third party utility.
  • For use with a third party utility create a truststore, e.g. https-truststore.p12, in PKCS12 format and import:
    • the Root CA certificate
  • For use with keytool create the truststore in PKCS12 or JKS format with the Root CA certificate. The examples below show one possible approach for certificate management. However, there are other ways to achieve similar results.
    

    • Example for importing a Root CA certificate to a PKCS12 truststore:

      Code Block
      language bash title Example how to import a CA-signed certificate into a PKCS12 Truststore
      # import Root CA certificate in PEM format to a PKCS12 truststore (https-truststore.p12) keytool -importimportcert -alias "root-ca" -file "RootCACertificate.crt" -keystore "JS7_CONTROLLER_CONFIG_DIR/private/https-truststore.p12" -storetype PKCS12

• On the Controller server specify the location of the truststore with the JS7_CONTROLLER_CONFIG_DIR/private/private.conf configuration file:

  • Example

    Code Block
    language text title Example for private.conf file specifying the Controller truststore
    js7 { web { # keystore and truststore locations for https connections https { truststores=[ { # Default: ${js7.config-directory}"/private/https-truststore.p12" file=${js7.config-directory}"/private/https-truststore.p12" store-password=jobscheduler } ] } } }

    
    

    Explanation:
    • js7.web.https.truststores.file is used for the path to the truststore.
    • js7.web.https.truststores.store-password is used for access to the truststore.

...

• On the Controller server create the client keystore using the keytool from your Java JRE or JDK or a third party utility.
  • For use with a third party utility create a client keystore, e.g. https-client-keystore.p12, in PKCS12 format and import:
    • the Controller private key and certificate for Client Authentication
    • the Root CA certificate
    • Intermediate CA certificatescertificate(s)
  • For use with keytool create the client keystore in PKCS12 or JKS format according to the steps indicated in the JS7 - Controller HTTPS Connections: Step 1: Create Controller Keystore article.
    • Apply the steps described to the client keystore and use the private key/certificate pair for Client Authentication.

• The location of the client keystore is added to the JS7_CONTROLLER_CONFIG_DIR/private/private.conf configuration file as shown:

  • Example for PKCS12 client keystore:

    Code Block
