Network permissioning
=====================

The keystore located in ``<workspace>/certificates/sslkeystore.jks`` is required to connect to the Corda network securely. 
In development mode (when ``devMode = true``, see ":doc:`corda-configuration-file`" for more information) a pre-configured
keystore will be used if the keystore does not exist. This is to ensure developers can get the nodes working as quickly
as possible.

However this is not secure for the real network. This documentation will explain the procedure of obtaining a signed
certificate for TestNet.

Initial Registration
--------------------

The certificate signing request will be created based on node information obtained from the node configuration. 
The following information from the node configuration file is needed to generate the request.

:myLegalName: Your company's legal name. e.g. "Mega Corp LLC". This needs to be unique on the network. If another node
    has already been permissioned with this name then the permissioning server will automatically reject the request. The
    request will also be rejected if the name contains a ``=`` or ``,``.

    .. note:: In a future version the uniqueness requirement will be relaxed to a X.500 name. This will allow differentiation
        between entities with the same name.

:nearestCity: e.g. "London"

:emailAddress: e.g. "admin@company.com"

:certificateSigningService: Certificate signing server URL. A certificate signing server will be hosted by R3 in the near
    future.  e.g."https://testnet.certificate.corda.net"

A new pair of private and public keys generated by the Corda node will be used to create the request.

The utility will submit the request to the network permissioning server and poll for a result periodically to retrieve the certificates.
Once the request has been approved and the certificates downloaded from the server, the node will create the keystore and trust store using the certificates and the generated private key.

.. note:: You can exit the utility at any time if the approval process is taking longer than expected. The request process will resume on restart. 

This process only is needed when the node connects to the network for the first time, or when the certificate expires.


Starting the Registration
-------------------------

You will need to specify the working directory of your Corda node using ``--base-dir`` flag. This is defaulted to current directory if left blank.
You can also specify the location of ``node.conf`` with ``--config-file`` flag if it's not in the working directory.

**To start the registration**::

    java -jar corda.jar --initial-registration --base-dir <<optional>> --config-file <<optional>>

A ``certificates`` folder containing the keystore and trust store will be created in the base directory when the process is completed.

.. warning:: The keystore is protected by the keystore password from the node configuration file. The password should kept safe to protect the private key and certificate.
