Download Certificate

As soon as your certificate has been issued, you will be able to download it and install the certificate on your web server. Issued certificates can be downloaded both from the certificates list as well as from the installation page.

When downloading a certificate, you will receive a ZIP file containing the following items:

  • certificate.crt: This file contains your primary SSL certificate, ready to be installed on your server.
  • ca_bundle.crt: This file contains only one intermediate certificate (ZeroSSL CA). The root certificate that signs this immediate certificate is trusted by all browsers and almost all other SSL clients. If you need the full chain including the root certificate we recommend you use a tool like to download it.
  • private.key: This file contains your private key, which will need to be uploaded to your server as well.

Missing Private Key?

There are two main reasons why your downloaded certificate (.zip) folder might not contain a private.key file. To learn more, please read this article.
