Support different CA

[espen]

Have you considered supporting different CAs? I don't know so much about ACME works but it seems to be it should be just switching the URL? Then again I don't know ACME so I could be wrong here. So https://zerossl.com could be supported? I guess it would require some naming changes in this gem though :)

btw this gem looks great. I was hoping not to use it though as I would prefer to outsource cert handling (using ZeroSSL REST API - but they do not give out the private key in the API), so if I have to implement it this gem looks like a very good option.

If the Let's Encrypt API is implemented, I think it can support other providers. I had read the ZeroSSL a few years ago, I think I didn't try to support it because I have a similar problem you are mentioned.

It is my understanding that both Let's Encrypt and ZeroSSL have the same ACME API. There seems to be some authentication differences that will be supported in acme-client soon: unixcharles/acme-client#210

When that is supported it should be sufficient for this gem to offer a way to change the endpoint as well as supplying the additional required credentials needed for zerossl.
