This feature-related FAQ. For general FAQ for this project see www.autoacme.net.

Will AutoACME support SAN/UCC certificates (multiple hostnames per certificate)?

Historically, my stance was not to support SAN certificates. (explanation). However, the restriction of 20 certificates per domain changed my position. It still does not make sense from IIS+CCS perspective, but it DOES make sense by allowing to get certificates for 2000 hosts instead of 20 hosts.

A "manual" process as outlined in the explanation is available as of version 1.6.0. In order for IIS to find the certificates in the CCS, identical copies of the certificates are stored as different files.

Will AutoACME support wildcard certificates (*.example.com)?

Wildcard certificates require DNS authorization, and does in consequence not work with the default redirection-based HTTP authorization approach initially used by AutoACME. In fact, AutoACME was initially built explicitly for avoiding the need for DNS authorization.

However, both DNS authorization (requires a MS DNS Server) and wildcard support are implemented as of version 1.6.0.
