Can I use the same CSR to renew certificate?

It is recommended that you generate a CSR each time you renew your old certificates. Though some web servers may allow you to use the old CSR, generating a new one takes care of incorporating new encryption methods and hashing algorithms into the new certificates.

Some certificates may require you to re-complete a step of the validation process as well.

Why do certificates expire?

To help ensure that all certificates are using the latest security standards and in fact controlled by the current certificate owner, we expire them. New certificates are issued using the latest security standards, processes and a re-confirmation of domain control and organization identity.
