crypto

The GigaVUE node by default generates and uses a self-signed certificate to provide HTTPS access for GigaVUE‑FM to communicate and manage GigaVUE node. It also facilitates the user to utilize ACME to manage web certificates. Use the crypto command to configure and manage certificates for the GigaVUE H Series node’s built-in Web server, performing the following tasks:

■

Generate the certificate and key pairs on the GigaVUE H Series node. This overwrites the existing certificate and key pair regardless of whether the previous certificate and key pair was self-signed or user added. You can specify how long the new self-signed certificate lasts with the days-valid argument.

■

Replace a signed certificate with one created by an administrator or generated by a 3rd party certificate authority.

■

Generate a certificate request and upload it to a specified URL. Default values for the certificate request can be configured.

■

The user can also utilize ACME to issues, renew and revoke web certificates.

The crypto command has the following syntax:

The following table describes the arguments for the crypto command:

Argument

Description

acme client clear

Utilize this command to clear the ACME issued certificate from the system. Once the ACME certificate is deleted, the web server will use the default certificate. This command also cancels the auto-renewal timers that are started by the ACME client in the device.

upload <upload URL>

Generates a certificate request message and uploads the request to the specified URL.

The supported formats for upload are: SCP, SFTP, and FTP.

For example:

(config) # crypto cert-req-msg generate upload scp://gigatest@192.168.1.2/tmp/Password (if required): ********Successfully uploaded certificate signing request with name 'cert-req-filebWdanb.csr'Successfully uploaded private key with name 'cert-req-filebWdanb.key'

   country-code <country code>
   days-valid <number of days>
   email-addr <email address>
   key-size-bits <number of bits>
   locality <locality name>
   org-unit <organizational unit name>
   organization <organization name>
   state-or-prov <state or province name>

Configures default values for certificate request message generation as follows:

●

country-code—Specifies the default value for country code, in two alphanumeric characters.

●

days-valid—Specifies the default value for days valid. The range is from 1 to 65535 days.

●

email-addr—Specifies the default value for the organization’s contact email address, in a string.

●
