Our company runs an online shop platform where some shop owners use their own domains. Since we take care of the servers, we would like to mass-create certificates for around 6,000 different domains on our behalf.
I’ve consulted the docs about the rate limits (https://letsencrypt.org/docs/rate-limits/), but could not understand what the limits are in a particular situation where an entity requests such a large number of certs at once.
So, the questions are:
- Is it OK for a single entity to request certificates for thousands of domains owned by its customers? (In our case, we don’t profit from this feature)
- How long does it take to complete the cert issuance for 6k unique domains?
- (Related to 2.) What is the most efficient way for an entity to create thousands of certificates?
Similar topic: Does let’s encrypt has limitation on the number of certificates that can be issued for one server?
The difference from the aforementioned topic is that the original poster wanted to know about the rate limits regarding renewals, my topic is about the mass-“creation” of certs.
