Brother Printer Automatic Certificate Renewal
This script will automate the certificate renewal of Brother printers.
Certificate table list
I recently decided to build a home lab and started to put SSL Certificate on web application hosted internally. My certificate is generated using ACME.SH by automatically generate a new valid certificate on *.mydomain.com. This way, I can use the certificate on multiple web application.
I was trying to find a way to automate the certificate renewal of my printer Brother MFC-L3750CDW and I didn't find any way to do it. Even online, there was no existing script from my research.
So, I created this python script that will automatically renew the certificate by doing request on the web administrative portal.
The only prerequisites is to pass the following arguments:
- Hostname or ip of your printer
- Filepath of the certificate
- 1.Authenticate on the web portal
- 2.Delete any existing certificate
- 3.Upload the new certificate
- 4.Select the new uploaded certificate in the dropdown menu
My certificate was generated this way by:
I'm using Cloudflare for my domain management.
/root/.acme.sh/acme.sh --issue --dns dns_cf -d *.mydomain.com
Then, once the certificate is generated, I export it in the PKCS12 format because this is the only format accepted on the Brother portal.
openssl pkcs12 -export -out brother.pfx -inkey .acme.sh/*.mydomain.com/*.mydomain.com.key -in .acme.sh/*.mydomain.com/*.mydomain.com.cer
brother.pfx is the file used to pass in the python script
Here is a preview of the execution of the script.
The script can be accessed on the following Github repository.
