Adding a Custom SSL Certificate

1. Navigate to Site Settings -> Hosting

Once you've purchased or generated a SSL certificate, you can add that certificate to your Gatsby Hosting domains. To do so, click "Add Custom Certificate" just above the list of current SSL certificates.

2. Enter Certificate Details

Enter your private key information first, including the lines -----BEGIN RSA PRIVATE KEY----- all the way through -----END RSA PRIVATE KEY-----. Next, you'll want to add your certificate and intermediate certificate information. Again, you will want to start with -----BEGIN CERTIFICATE---- and end with -----END CERTIFICATE----. We use Fastly under the hood for Gatsby hosting and it supports a key size of 2048 bits for RSA public key encryption.  

Depending on where you purchase or generate your certificate, the Certificate and Intermediate Certificate may be included in a single file.

3. Save and Confirm

Click Save and confirm that your new certificate is included in your list of SSL certificates. Custom certificates will have a "Remove" option which differentiates them from auto-generated certificates.

Note: this feature is only available on Professional and Enterprise plans.
