Since I had last posted about using Let's Encrypt with NearlyFreeSpeech, NFS has changed their process for setting TLS info. Instead of putting the various files in /home/protected/ssl and submitting an assistance request, now there is a command to submit the certificate info and a webpage for submitting the certificate info.
The webpage is https://members.nearlyfreespeech.net/{username}/sites/{sitename}/add_tls
and has a textbox for you to paste in all the cert info in PEM form into the textbox. The
domain key, the domain certificate, and the Let's Encrypt intermediate cert must be pasted into the textbox and submitted.
Alternatively, that same info may be provided as standard input to nfsn -i set-tls
To renew my certificate with the updated NFS process I followed the commands from Andrei Damian-Fekete's script which depends on acme_tiny.py:
python acme_tiny.py --account-key account.key --csr domain.csr --acme-dir /home/public/.well-known/acme-challenge/ > signed.crt
wget -O - https://letsencrypt.org/certs/lets-encrypt-x3-cross-signed.pem > intermediate.pem
cat domain.key signed.crt intermediate.pem > chained.pem
nfsn -i set-tls < chained.pem
Because
my certificate had already expired I needed to comment out the section in acme_tiny.py that validates the challenge file. The filenames in the above map to the following:
