The combination of the ACME protocol, pfSense software, and Cloudflare service is represented by the “pfSense ACME Cloudflare API token”. At Bobcares, with our pfSense Support Services, we can handle your pfSense issues.

More on “pfSense ACME Cloudflare API token”

With Let’s Encrypt SSL/TLS certificates, pfSense can automatically manage them using the Cloudflare API token for DNS-01 challenge validation thanks to the “pfSense ACME Cloudflare API token” integration. Let’s look into the workings of this combinational setup.

Working

1. An ACME package built into pfSense makes it easier to automatically issue and renew Let’s Encrypt SSL/TLS certificates.

2. The domain ownership can be verified using the ACME protocol using several sorts of challenges when getting SSL/TLS through Let’s Encrypt. DNS-01 is one of the challenge kinds that entails adding particular DNS records to the domain’s DNS zone.

3. pfSense requires permission to change DNS records in the Cloudflare account linked to the domain in order to carry out DNS-01 challenge validation using Cloudflare as the DNS provider. pfSense may use the more secure Cloudflare API token in place of the API key, which grants extensive access.

4. Using their Cloudflare account, admins create an API token that grants them the ability to change DNS records for the designated domain. They can restrict the token’s use such that the ACME program can only use it in order to update DNS records in order to validate Let’s Encrypt.

5. Admins set the Cloudflare API token, which serves as the login details for the Cloudflare API, in the pfSense ACME package setup.

6. The ACME package starts the DNS-01 challenge when pfSense has to seek or renew an SSL/TLS from Let’s Encrypt. The necessary DNS record is programmatically added to the Cloudflare DNS zone for domain validation using the Cloudflare API token.

7. Using the Cloudflare API, Let’s Encrypt confirms the existence of the DNS record that pfSense inserted. Upon verification of domain ownership, Let’s Encrypt then issues the SSL/TLS certificate.

8. Then the ACME package installs this SSL/TLS certificate into the pfSense setup. This allows secure connection for network services like as web servers and VPNs.

9. The ACME package ensures that SSL/TLS certificates are always valid and up to date by setting up an automatic renewal procedure.
