Description: Tiny ACME client for Let's Encrypt
- This tiny ACME client written is with process isolation and minimal privileges
- in mind. It is divided into three components:
- 1. the "master" process, which runs as root and is the only component
- with access to the private key material (both account and server keys);
- 2. the actual ACME client, which runs as a separated user ID, builds ACME
- requests and dialogues with the remote ACME server (data to be signed is
- written to a pipe shared with the master process, which replies with its
- SHA-256 signature); and
- 3. an optional webserver, which runs as www-data:www-data and listen on port
- 80 to server ACME challenges.
+ Tiny ACME client written with process isolation and minimal privileges in
+ mind. It is divided into four components, each with its own executable:
+ .
+ * A process to manage the account key and issue SHA-256 signatures needed for
+ each ACME command. (This process binds to a UNIX-domain socket to reply to
+ signature requests from the ACME client.) One can use the UNIX-domain
+ socket forwarding facility of OpenSSH 6.7 and later to run this process on
+ a different host.
+ .
+ * A "master" process, which runs as root and is the only component
+ with access to the private key material of the server keys. It is used to
+ fork the ACME client (and optionally the ACME webserver) after dropping
+ root privileges. For certificate issuances, it also generates Certificate
+ Signing Requests, then verifies the validity of the issued certificate, and
+ optionally reloads or restarts services.
+ .
+ * An actual ACME client, which builds ACME commands and dialogues with
+ the remote ACME server. Since ACME commands need to be signed with the
+ account key, the "master" process passes the UNIX-domain socket of the
+ account key manager to the ACME client: data signatures are requested by
+ writing the data to be signed to the socket.
+ .
+ * For certificate issuances, an optional webserver, which is spawned
+ by the "master" process when no service is listening on the HTTP port.
+ (The only challenge type currently supported is "http-01", which requires a
+ webserver to answer challenges.) That webserver only processes GET and
+ HEAD requests under the "/.well-known/acme-challenge/" URI. By default
+ some iptables(1) rules are automatically installed to open the HTTP port,
+ and removed afterwards.
