Let's Encrypt and GlobalSign certificates

Hello everyone

We have purchased an HCP license, and plan to automate the full lifecycle management of Let’s Encrypt and GlobalSign certificates.

Just for a bit of context, we currently do this manually, we point directly to the CA servers via shell scripts.

Let’s Encrypt use cases with Vault

I saw in the documentation that it was possible to configure Vault as an ACME server and have it communicate with an ACME client.
I would like to know if the certificates that are generated by doing this are standard Let’s Encrypt certificates as we have them today?
If not, how to interface Vault with the Let’s Encrypt server?

GlobalSign Use Cases
How to interface Vault with CA GlobalSign

Can someone send me the documentation that details the implementation of these two use cases? I’m lost in all the PKI documentation.
