Node Registration Tool
![Click to copy the section link. heading-link-icon](/icons/chain-icon.png)
The registration tool can be used to register multiple Corda nodes with the network operator, it is useful when managing multiple identities and setting up multiple Corda nodes sharing Corda firewall infrastructures. For convenience the tool is also downloading network parameters. Additionally, the tool can use the crypto services configured in the bridge (if any) to generate SSL keys and import them into the bridge.
The tool does not include any third party supplied client side jar files needed when connecting to an HSM. These jar files are supplied by the HSM vendor. The tool does however assume that it can load these jar files from the drivers sub directory of the configured base-directory option. Before running the tool you need to make sure the required HSM client side jar files are in the drivers directory. This is only necessary when connecting to an HSM.

Keys and certificates
![Click to copy the section link. heading-link-icon](/icons/chain-icon.png)
The following table shows keys and certificates generated by the tool. For more details on a certificate hierarchy see permissioning.
Certificate | Max validity [1] | Alias | File store | Steps to generate |
---|---|---|---|---|
Node CA | 20 years | cordaclientca | nodekeystore.jks |
|
Node Identity | 20 years | identity-private-key | nodekeystore.jks |
|
Node TLS | 10 years [2] | cordaclienttls- | sslkeystore.jks |
|
[1] Certificate validity cannot exceed the validity of Doorman CA certificate.
[2]
For Node TLS certificate it’s recommended to set 27 months validity by specifying --tls-cert-validity 825
.
[3] HSM for TLS keys is only supported with standalone bridge component. TLS keys for ‘all-in-one’ node can be only stored in file.
Registering nodes with bridge
![Click to copy the section link. heading-link-icon](/icons/chain-icon.png)
Before running the tool you need to copy the configuration files from Corda nodes and bridge running on different servers into the same location, for example, as follows:
.
├── corda-tools-ha-utilities-4.12.jar
├── drivers
├── <HSM driver>
├── entity_A
├── node.conf
├── HSM.conf
├── entity_B
├── node.conf
├── HSM.conf
├── bridge
├── firewall.conf
├── HSM.conf
Given the configuration above, the tool can be run with the following command:
java -jar corda-tools-ha-utilities-4.12.jar node-registration --base-directory=./output --config-files=./entity_A/node.conf --config-files=./entity_B/node.conf --bridge-config-file=./bridge/firewall.conf --network-root-truststore=network-root-truststore.jks --network-root-truststore-password=trustpass --tls-cert-validity 825
After successful execution this will produce output/ folder containing the following files:
.
├── output
├── entity_A
├── certificates
├── nodekeystore.jks
├── sslkeystore.jks
└── truststore.jks
├── entity_B
├── certificates
├── nodekeystore.jks
├── sslkeystore.jks
└── truststore.jks
├── network-parameters
└── bridge.jks
Generated files need to be copied from the output dir to the actual node and bridge locations, as follows:
Source | Destination |
---|---|
Renewing TLS certificates
![Click to copy the section link. heading-link-icon](/icons/chain-icon.png)
The tool allows to re-issue TLS certificate, which validity is shorter than the validity of corresponding Node CA certificate,
by specifying -r
or -R
option. In this case node re-registration will not occur, so Node CA and Node Identity keys and certificates
remain intact.
Option | Node TLS keys | Node Identity keys | Node CA keys |
---|---|---|---|
-r, –renew-tls-cert | not changed | not changed | not changed |
-R, –renew-tls-cert-with-keys | updated | not changed | not changed |
Pre-requisites for TLS certificate renewal are:
- All nodes are already registered with the tool.
- Configuration files which were used for initial registration are in place.
nodekeystore.jks
andsslkeystore.jks
files produced by the tool during initial registration remain at the same output location.
Given the configuration above, TLS certificates can be renewed with the following command:
java -jar corda-tools-ha-utilities-4.12.jar node-registration --base-directory=./output --config-files=./entity_A/node.conf --config-files=./entity_B/node.conf --bridge-config-file=./bridge/firewall.conf --network-root-truststore=network-root-truststore.jks --network-root-truststore-password=trustpass --tls-cert-validity 825 --renew-tls-cert
This will update certificates in sslkeystore.jks
and bridge.jks
at the output location.
SSL key copier
![Click to copy the section link. heading-link-icon](/icons/chain-icon.png)
When using shared external bridge, the bridge will need to have access to nodes’ SSL key in order to establish connections to counterparties on behalf of the nodes. The SSL key copier sub command can be used to provision the SSL keystore and add additional keys when adding more nodes to the shared infrastructure.
--bridge-config-file
option, so there is no need to explicitly run SSL key copier in such case.Command-line options

Self signed internal Artemis SSL keystore
![Click to copy the section link. heading-link-icon](/icons/chain-icon.png)
TLS is used to ensure communications between HA components and standalone Artemis are secured. This tool can be used to generate the required keystores if TLS cert signing infrastructure is not available within your organisation.
Please note that for Artemis to work correctly, the password for the store and the password for the private key will need to be set to the same value.
This tool can generate the private key used by the Bridge or the Node in an HSM.
This will happen if the --bridge-hsm-name
and --bridge-hsm-config-file
options are specified. Otherwise the file-based keystore is used.
Regardless where the private keys are stored the public certificates are stored in the file based keystores.
The tool does not include any third-party supplied client side JAR files needed when connecting to an HSM. These JAR files are supplied by the HSM vendor. The tool does however assume that it can load these JAR files from the drivers
sub-directory of the configured base directory option. Before running the tool you need to make sure the required HSM client side JAR files are in the drivers
directory.
This is only necessary when connecting to an HSM.
The following files are produced when you run the tool:
artemisbridge.jks
: used by the standalone bridge. The path to this file should be specified in theartemisSSLConfiguration
section infirewall.conf
.artemisnode.jks
: optionally used by the node. When used, the path to this file should be specified in themessagingServerSslConfiguration
section innode.conf
.artemis.jks
: used by the standalone P2P Artemis broker.artemis-truststore.jks
: must be placed together with any of the above keystore files.

Artemis configuration
![Click to copy the section link. heading-link-icon](/icons/chain-icon.png)
Configuring an external Artemis broker to be used by Corda nodes and firewall components can be a little daunting. This tool will generate the necessary configuration files and install (if needed) a new Artemis instance. Please note that the generated configuration files will be copied to a destination supplied as an argument to the command, replacing existing ones. The keystore and truststore information will be downloaded by the clients when Artemis is configured in HA mode. Therefore, the tool will configure broker.xml with paths relative to the Artemis instance (for acceptors) and client’s working directory (for connectors). For example, using the option –keystore ./artemiscerts/keystore.jks will require the keystore to be installed in $ARTEMIS_DIR/etc/artemiscerts and $NODE_OR_BRIDGE_DIR/artemiscerts.

Notary registration
![Click to copy the section link. heading-link-icon](/icons/chain-icon.png)
The HA Utilities tool is used to register the identity of the HA notary service, and generates the key and certificate of the notary service that is shared by all workers of the notary cluster. It is required to be run before registering any notary worker nodes.
The tool does not include any third party supplied client side jar files needed when connecting to an HSM. These jar files are supplied by the HSM vendor. The tool does however assume that it can load these jar files from the drivers sub directory of the configured base-directory option. Before running the tool you need to make sure the required HSM client side jar files are in the drivers directory. This is only necessary when connecting to an HSM.

Output
![Click to copy the section link. heading-link-icon](/icons/chain-icon.png)
After successful registration, a keystore file is created by the tool. The location of this file can be explicitly set using the optional
–output-keystore commandline argument. If this argument has not been passed then the file location will default to
certificates/nodekeystore.jks
.
This key store contains the service identity certificate (and key if not using a HSM) that all notary workers of this notary cluster share. Due to HSM restrictions around storing certificate chains, the key store will still be generated when using a HSM however it will only contain the notary service certificate chain. See HSM Support for more information.
Node Certificate Rotation Tool
![Click to copy the section link. heading-link-icon](/icons/chain-icon.png)
This tool enables the reissuing of node legal identity keys and certificates, allowing for re-registration of a node (including a notary node) with a new certificate in the Network Map in Corda Enterprise Network Manager. You must not change the node’s myLegalName
during certificate rotation.
For more information about this feature, contact your R3 account manager.
