ACME is the Automated Certificate Management Environment. It’s a mechanism to allow tools to automatically do the following:
Provision and renew certificates
Install them in the right place
Many Certificate Authorities provide ways to interact with them via ACME, but in particular, LetsEncrypt provides certificate services for free.
ACME uses a challenge mechanism to verify that you own the server you are trying to generate a certificate for. This is done either over TCP port 80 (the simplest mode) or over DNS (more complex).
There are tools to assist with this process. However, 12d Synergy requires that your certificate be in the Personal and Trusted People Certificate stores, and most ACME tools in the market will not support this.
12d Synergy has developed a new tool that helps with certificate renewal and installation. It is automatically installed with 12d Synergy Version 5.1.7.833 and later. It is not mandatory to use this app, but we recommend its use as it makes the process easier.
