HardenedBSD 11-STABLE has now migrated to LibreSSL as the default cryptography library in base. We've already published a binary update for you hbsd-update users.
The 11-STABLE package repo was taken offline until it could be freshly rebuilt. The rebuild process has been completed and the repo is back online. You will, of course, need to update base before updating packages.
Because of the severity of this type of change, you will need to reinstall all the packages on your system.
Instructions for reinstalling packages:
1. If you use secadm: secadm flush
2. pkg-static clean -y
3. pkg-static upgrade -f
4. If you use secadm: service secadm start
