SignServer Cloud TLS Certificate Generation Guide

This guide is intended to show an administrator of a SignServer Cloud AWS instance how to generate new Transport Layer Security (TLS) certificates.

For information on AWS Public IP addressing, refer to the AWS documentation on Public IPv4 Addresses and External DNS Hostnames.

Overview

New TLS certificates are needed in the following circumstances:

SignServer Cloud instance is shut down within the Amazon environment and the Public IP is released by Amazon.
An Elastic IP is added to the instance in place of the Public IP for persistence.
A custom DNS name is desired.

When using tools such as the ClientToolBox, the following error may be displayed:

"No subject alternative DNS name matching <instance ip>.compute-1.amazonaws.com found".

If this is encountered, perform the steps in this guide.
