Acme DNS-01 for Hurricane Electric needs to be updated for new dynamic update methods
Hurricane Electric has added (as of two days ago - see http://dns.he.net) dynamic DNS support for TXT records allow for updating ACME DNS-01 style authentication without needing to store the entire account key on the pfsense box. The "DNS-Hurricane Electric" method for certificate issue/renewal should be updated (or a new DNS option added) to use the improved method.

Thanks for the insight. I've opened https://github.com/acmesh-official/acme.sh/issues/3038 which will hopefully lead to acme.sh getting updated. Thanks.
