Having libressl (LibreSSL 2.3.2) in your path breaks the script since libressl does not support sha.

openssl:Error: 'sha' is an invalid command.

Maybe add the possibility to override the openssl binary path in the config file?

What I do right now is forcing the path manually:

sudo sh -c 'PATH="/usr/bin:$PATH";./letsencrypt.sh --cron --force -f config.sh'

I think the correct solution would be to use openssl dgst -sha256 in the script. openssl sha seems to be a legacy command. This will be fixed soon.
