Custom SSL Certificates

If you have an existing SSL certificate purchased from an external certificate authority, you can attach it to any of your custom domains for Servd to use.

Servd expects your certificate to have two elements:

  • The private key used to generate the certificate
  • The full certificate chain

These can be stored in several different formats and you might need to convert them to match Servd's expectations.

Servd expects your private key to be an RSA 2048 (or greater) key, and look something like this:

-----BEGIN PRIVATE KEY-----

The certificate chain should include all of the leaf/server and intermediate certificates which you have been provided. They should be saved in a PEM-encoded X.509, with the leaf/server certificate first, and look something like this:

Once you have these files ready you can add the SSL certificate to any of your custom domains by clicking the 'Use Custom' button on the Project Settings > Domains page in the Servd dashboard.

Simply paste in your files and 'Save'

Once updated you'll need to run a 'Sync' to get your changes deployed.
