Custom SSL cert

Hi there,

We've been hosting our angular app on Divshot, and are looking to add SSL for some custom domains. Since it looks like Divshot was recently acquired by Firebase, we've been looking into how to do this with Firebase hosting.

Divshot's docs outline a clear process for uploading a custom SSL cert. I couldn't find anything comparable in the Firebase hosting docs.

I'm assuming Firebase hosting must offer this functionality since you've acquired Divshot -- how do I upload my own SSL cert?

I'm already aware of the following threads:

The last thread in particular talks about "supplying your own certificate", which makes me hopeful that this is doable.

I'm also aware that in the first thread, Firebase "(doesn't) request an individual certificate for your domain" when you request certs after a custom domain is registered, but it also makes it sound like it's possible to upload custom SSL certs.

The enterprise client I'm building the app for has a security policy requiring them to be the only domain for which a certificate (that they provide) applies. They've also asked me to issue a CSR.

So, to recap, my questions are:

How do I upload my own SSL cert to Firebase?
What should I use for the Common Name on the CSR they'll be using to create the cert?

Thanks in advance,

JD

Hi JD,

Firebase automatically provisions SSL certs for https://<YOUR-FIREBASE-APP>.firebaseapp.com and for your custom domain, when your configure it in our hosting tools. You can provision SSL certs for any other domains/subdomains you point to your own server, but there is no need to upload a cert for your Firebase hosted assets.

Hi Kato,

Thanks, but I've already reviewed those docs.

I'm aware there's no _need_ since you're already provisioning a cert. Like I mentioned, it's more that the security requirements for my enterprise client specify I need to upload an SSL cert they provision.

I'm coming to Firebase from Divshot, which offers this functionality:

https://docs.divshot.com/guides/ssl

I assume since Firebase acquired Divshot, you must offer this functionality also.

Please let me know what I can do here since I'd like to continue using Firebase for our frontend hosting.

Thanks,

JD

Hi JD,

Unfortunately this is not something that's possible right now with Firebase Hosting nor is it planned for the foreseeable future. I can understand that for some sites there may be strict requirements around specific certificates, and sadly for now at least Firebase Hosting is probably not the best solution for those. It's just not something that we've seen requested, as most people are ecstatic not to have to deal with the pain of provisioning certs.

I will definitely count this as a vote for a custom certificate feature. If we continue to see requests along the same line it may be something we can revisit in the future. Wish I had better news, but best of luck to you!
