Introduction

  • The JS7 - Certificate Authority included with the JOC Cockpit benefits users by allowing them to create and rollout private keys and certificates.
  • The built-in Certificate Authority:
    • creates X.509 certificates for HTTPS Mutual Authentication
      • between JOC Cockpit and Controller instances,
      • between Primary and Secondary Controller instances,
      • between Controller instances and Agents.
    • is not used to create Server Authentication Certificates for access to JOC Cockpit. Access is performed by user browsers and therefore it is preferable to use a Server Authentication Certificate which has been signed by a known Certificate Authority and whose Root CA certificate is recognized by user's browsers.
  • Users benefit from the simplified rollout of private keys and certificates when using the built-in Certificate Authority.

JS7 provides a Certificate Rollout Client as part of the Controller and Agent instance's Start Scripts. This client creates and rolls out private keys and certificates using the built-in Certificate Authority. Rollout of private keys and certificates created with an external Certificate Authority are not in scope of the Certificate Rollout Client. The Certificate Rollout Client provides the following functions:

  • use of a security token to authenticate with the JOC Cockpit, see JS7 - Certificate Authority - Manage Certificates with JOC Cockpit for more information.
  • requesting a private key and certificate to be created by the JOC Cockpit on-the-fly,
  • updating a Controller or Agent instance's configuration for use of the private key and certificate with HTTPS mutual authentication.

Certificate Rollout

Rollout of certificates includes performing the following steps:

  • JOC Cockpit
  • Controller/Agent Instance
    • Both components include the Certificate Rollout Client which is available from the Controller/Agent Instance Start Script.
    • The Certificate Rollout Client connects to the JOC Cockpit. Authentication is performed using the one-time security token generated in the previous step.
    • The JOC Cockpit Certificate Authority is requested to create a private key and Server/Client Authentication Certificate for the specified host. The private key and certificate are created on-the-fly and are returned to the Certificate Rollout Client. In addition, the JOC Cockpit stores the certificate in the JS7 - Database.
      The Certificate Rollout Client:
      • stores the private key in a keystore file,
      • stores the Server/Client Authentication Certificate in a truststore file,
      • updates the configuration in the ./config/private/private.conf file.

Certificate Rollout Client

The Controller/Agent Instance Start Script includes the Certificate Rollout Client and is available from the following locations:

Standard Arguments

The following arguments are used independently of whether the connection to the JOC Cockpit is made with HTTP or HTTPS:

ArgumentRequiredDescriptionExample
--joc-uriYes

URI of the JOC Cockpit instance from which to receive the private key and certificate.

--joc-uri=http://myhost.example.com:4446

JKS (deprecated).

--target-keystore-type=PKCS12
--target-keystore-passNo

Password for access to the keystore.

--target-keystore-pass="YourKeystorePassword"

--target-truststore-passNo

Password for access to the truststore.

--target-truststore-pass="YourTruststorePassword"

--helpNoDisplays usage information, this option has to be specified as the only command line option and has no value.


Explanation:

  • Arguments qualified as required have to be used with any request made to the JOC Cockpit to create a private key and certificate.
  • The --joc-uri argument specifies the URL for JOC Cockpit. When used with the HTTPS protocol then check the next section for additional arguments.
  • The --target-keystore is located in the Controller or Agent instance's ./config/private directory.

  • The --dn-only argument if present adds related DNs to the private.conf file in the Controller or Agent instances' ./config/private directory. No certificates/keys are generated.

Arguments for use with JOC Cockpit HTTPS Connections

The following arguments are used in addition to standard arguments if the JOC Cockpit has been set up for HTTPS connections:

ArgumentRequiredDescriptionExample
--source-truststoreNo

Path to the truststore holding the trusted certificate(s) to connect to JOC Cockpit by HTTPS.

--source-truststore=/home/sos/public/js7-truststore.p12
--source-truststore-typeNo

Type of the truststore used. Supported values include: PKCS12 (default),
JKS (deprecated).

--source-truststore-type=PKCS12
--source-truststore-passNo

Password for access to the truststore.

--source-truststore-pass="YourTruststorePassword"
--source-certificateNo

Path to a certificate file holding the JOC Cockpit server authentication certificate.

--source-certificate=/home/sos/public/js7-joc-cockpit.crt
--source-ca-certNo

Path to the CA certificate file(s) that are used to verify the JOC Cockpit server authentication certificate. A number of paths can be specified, separated by comma.

--source-ca-cert="/home/sos/public/intermediate_ca.crt, /home/sos/public/root_ca.crt"


Explanation:

  • An HTTPS connection to JOC Cockpit requires verification of the JOC Cockpit Server Authentication Certificate.
  • The --source-truststore-* arguments are used to specify a truststore that holds the Root CA Certificate and optionally any Intermediate CA Certificates involved in signing the JOC Cockpit Server Authentication Certificate.

  • The --source-certificate and --source-ca-cert arguments are used as an alternative to --source-truststore-* arguments in case that JOC Cockpit Server Authentication Certificates are available from individual files instead of being available from a common truststore. Supported certificate formats include PEM.

Arguments for use with JOC Cockpit HTTPS Connections using Mutual Authentication

The following arguments are used in addition to HTTPS connection arguments if the JOC Cockpit is set up for JOC Cockpit - HTTPS Mutual Authentication.

ArgumentRequiredDescriptionExample
--source-keystoreNo

Path of the keystore holding the client's private key and certificate for client authentication.

--source-keystore=/home/sos/private/js7-keystore.p12
--source-keystore-typeNo

Type of keystore used. Supported values include: PKCS12 (default),
JKS (deprecated).

--source-keystore-type=PKCS12
--source-keystore-passNo

Password for access to the keystore holding the private key for client authentication.

--source-keystore-pass="YourKeystorePassword"
--source-keystore-entry-passNo

Password for the private key entry in the keystore.

--source-keystore-entry-pass="YourKeystoreEntryPassword"
--source-private-keyNo

Path to the private key file holding the client authentication private key.

--source-private-key=/home/sos/private/client.key


Explanation:

  • An HTTPS connection to JOC Cockpit with mutual authentication requires:
    • verification of the JOC Cockpit Server Authentication Certificate by the requesting client and
    • verification of the Client Authentication Certificate of the requesting client by the JOC Cockpit.
  • The --source-keystore-* arguments are used to specify a keystore that holds the client's private key and certificate for client authentication.

  • The --source-private-key argument is used as an alternative to --source-keystore-* arguments if the private key is available from an individual file instead of a keystore.

Standard Examples

Example for use with the Controller/Agent Instance Start Script and default values

with instance startscript and default values
# use with a Controller instance
./bin/controller_instance.sh cert --token=73bfc4b8-3f15-44b9-a75b-cdb44aec8f4b --joc-uri=https://myhost.example.com:4446

Explanation:

  • the cert argument for the Instance Start Script is used to build the Java classpath and start the Java executable.
  • The --token argument specifies the one-time token to connect to JOC Cockpit.
  • The --joc-uri argument specifies the URL for JOC Cockpit.
  • If no additional arguments are used then the Command Line Client determines default values for the Keystore and Truststore from the instances' ./config/private/private.conf configuration file, including defaults for the DN and for the SAN of the certificate.

Example for use with the Controller/Agent Instance Start Script to update relevant DN entries

with instance startscript and default values
# use with a Controller instance
