Generate New Public Key

How do I regenerate my certificate and force the public key to change too? it seems the public key stays the same every time my certificate is renewed.

What ACME client are you using? How did you generate the keypair and certificate?

I believe most ACME clients generate new keypairs when issuing new certificates by default.

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g., so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command:

It produced this output:

My web server is (include version):

The operating system my web server runs on is (include version):

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don’t know):

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):

I used certbot. I followed exactly.

Everything works fine, but every time i renew the certificate, the public key seems to stay the same. I need to change it.

(I’d rather not disclose my domain - I hope that’s ok :slight_smile:)

Certbot always creates new keypairs by default, including when you follow that tutorial.

and your cronjob, if this parameter is defined.
