# Modified by: Brielle Bruns <bruns@2mbit.com>
# Download URL: https://source.sosdg.org/brielle/lets-encrypt-scripts
# Version: 1.8
# Last Changed: 09/22/2021
# 02/02/2016: Fixed some errors with key export/import, removed lame docker requirements
# 02/27/2016: More verbose progress report
# 03/08/2016: Add renew option, reformat code, command line options
# 03/24/2016: More sanity checking, embedding cert
# 10/23/2017: Apparently don't need the ace.jar parts, so disable them
# 02/04/2018: LE disabled tls-sni-01, so switch to just tls-sni, as certbot 0.22 and later automatically fall back to http/80 for auth
# 05/29/2018: Integrate patch from Donald Webster <fryfrog[at]gmail.com> to cleanup and improve tests
# 09/26/2018: Change from TLS to HTTP authenticator
# 09/22/2021: Update root certs
# Location of LetsEncrypt binary we use. Leave unset if you want to let it find automatically
#LEBINARY="/usr/src/letsencrypt/certbot-auto"
