Generate a Certificate Signing RequestΒΆ

The Certificate Signing Request (CSR) contains a public key derived from the key pair generated in the previous step, plus attributes that uniquely identify the requester. A CSR is signed by a Certificate Authority to generate a certificate.

To generate a CSR, first set values which identify this TNSR instance:

tnsr# pki signing-request set common-name tnsr-example.netgate.com
tnsr# pki signing-request set country US
tnsr# pki signing-request set state Texas
tnsr# pki signing-request set city Austin
tnsr# pki signing-request set org Netgate
tnsr# pki signing-request set org-unit Engineering Testing 1 2 3

For the Common Name, enter the fully qualified domain name or Public IP address of the TNSR instance. For the other fields, enter information about the name and location of the organization controlling this TNSR instance.

A Digest Algorithm is also required to sign the request:

tnsr# pki signing-request set digest sha256

View the values that have been set before generating the request:

Certificate signing request fields:
    common-name: tnsr-example.netgate.com
    country: US
    state: Texas
    city: Austin
    org: Netgate
    org-unit: Engineering Testing 1 2 3
    digest: sha256

Any typos can be corrected by re-running the appropriate set commands.

When all values are correct, generate the request:

Warning

As with the key pair, the request must have the name tnsr-updates.
