LetSyncrypt

LetSyncrypt is a Let's Encrypt client for Synchronet which uses the ACMEv2 protocol.

Setup

LetSyncrypt should be added as a timed event.

Add the Timed Event in SCFG->External Programs->Timed Events:

Internal Code                   SYNCRYPT
Start-up Directory
Command Line                    ?letsyncrypt.js
Enabled                         Yes
Execution Node                  1
Execution Months                Any
Execution Days of Month         Any
Execution Days of Week          All
Execution Frequency             1 times a day
Requires Exclusive Execution    No
Force Users Off-line For Event  No
Native Executable               No
Use Shell to Execute            No
Background Execution            No
Always Run After Init/Re-init   Yes

If you have multiple domain names, you can have LetSyncrypt put them all in a single certificate, even if you have virtual hosts. Edit the ctrl/letsyncrypt.ini file and add a [Domains] section where the key is the hostname, and the value is the web root for that domain:

[Domains]
nix.synchro.net=/sbbs/web/root
home.bbsdev.net=/sbbs/web/root
gallery.bbsdev.net=/sbbs/web/root/gallery.bbsdev.net
pics.bbsdev.net=/sbbs/web/root/pics.bbsdev.net

This example has four domains (nix.synchro.net, home.bbsdev.net, gallery.bbsdev.net, and pics.bbsdev.net). The last two are virtual hosts, so have their web root as a subdirectory of the main web root.

Do not modify any other sections of this file.

Important Caveat

At present (February 24, 2018), Let's Encrypt does not support ACMEv2 for trusted certificates. The server is expected to go live on February 27, 2018. On that date, letsyncrypt.js will be updated to use the newly announced server (likely acme-v02.api.letsencrypt.org). Until then, installed certificates will not be trusted, being issued by the staging server, signed by “Fake LE Intermediate X1”.
