Administration#

This chapter describes administrative tasks for users with the Administrator role. Please refer to chapter Roles to learn more about the role.

Important

Please make sure you read the information in the beginning of this document before starting to work.

System Management#

Device Information#

The vendor and product information for a NetHSM can be retrieved as follows.

Example

$ nitropy nethsm --host $NETHSM_HOST info

Host:    localhost:8443
Vendor:  Nitrokey GmbH
Product: NetHSM

Boot Mode#

NetHSM can be used in Attended Boot mode and Unattended Boot mode.

Boot Mode	Description
Attended Boot	The Unlock Passphrase needs to be entered during each start, which is used to decrypt the User Data. For security reasons, this mode is recommended.
Unattended Boot	No Unlock Passphrase is required, therefore the NetHSM can start unattended. Use this mode if your availability requirements can not be fulfilled with Attended Boot mode.

The current boot mode can be retrieved as follows.

Example

$ nitropy nethsm --host $NETHSM_HOST get-config --unattended-boot

Configuration for NetHSM localhost:8443:
   Unattended boot: off

The boot mode can be changed as follows.

Arguments

Argument	Description
Status	Enable or disable Unattended Boot. Can have value `on` or `off`.

Example

$ nitropy nethsm --host $NETHSM_HOST set-unattended-boot on

Updated the unattended boot configuration for NetHSM localhost:8443

State#

The NetHSM software has four states: Unprovisioned, Provisioned, Locked, and Operational.

State	Description
Unprovisioned	NetHSM without configuration (factory default)
Provisioned	NetHSM with configuration. The Provisioned state implies either Operational or Locked state.
Operational	NetHSM with configuration and ready to execute commands. The Operational state implies the Provisioned state.
Locked	NetHSM with configuration but protected (requires unlock). The Operational state implies the Provisioned state.

The current state of the NetHSM can be retrieved as follows.

Example

$ nitropy nethsm --host $NETHSM_HOST state

NetHSM localhost:8443 is Unprovisioned

A new NetHSM has an Unprovisioned state and after provisioning enters the Operational state. The provisioning of a NetHSM is described in the chapter Provisioning.

A NetHSM in Operational state can be locked again to protect it as follows.

Example

$ nitropy nethsm --host $NETHSM_HOST lock

NetHSM localhost:8443 locked

A NetHSM in Locked state can be unlocked as follows.

Example

$ nitropy nethsm --host $NETHSM_HOST unlock

NetHSM localhost:8443 unlocked

Unlock Passphrase#

The Unlock Passphrase is used to derive an Unlock Key if the NetHSM is in Locked state. The passphrase is initially set during provisioning of the NetHSM.

The Unlock Passphrase can be set as follows.

Optional Options

Option	Description
`-p`, `--passphrase` `TEXT`	The new unlock passphrase

Example

$ nitropy nethsm --host $NETHSM_HOST set-unlock-passphrase

Passphrase:
Repeat for confirmation:
Updated the unlock passphrase for localhost:8443

TLS Certificate#

The TLS certificate is used for the HTTPS based REST API, and thus also used by nitropy. During provisioning a self-signed certificate is created. The certificate can be replaced, for example with a signed certificate from a certificate authority (CA). In this case a Certificate Signing Request (CSR) must be generated. After signing the certificate must be imported to the NetHSM.

A change is only necessary when the certificate is to be replace. Such change may be to replace it with a signed certificate from a certificate authority (CA).

The TLS certificate can be retrieved as follows.

Required Options

Option	Description
`-a`, `--api`	Set the certificate for the NetHSM TLS interface

Example

$ nitropy nethsm --host $NETHSM_HOST get-certificate --api

The TLS certificate can be generated as follows.

Required Options

Option	Description
`-t`, `--type` `[RSA\|Curve25519\|EC_P224\|EC_P256\|EC_P384\|EC_P521]`	The type for the generated key
`-l`, `--length` `INTEGER`	The length of the generated key

Example

$ nitropy nethsm --host $NETHSM_HOST generate-tls-key -t Curve25519

Key for TLS interface generated on NetHSM localhost:8443

The Certificate Signing Request (CSR) for the certificate can be generated as follows.
