Wildcard certificates for strato.de
Create strato-auth.json:
{
"username": "<username>",
"password": "<password>"
}Make sure to make this file only readable for root:
sudo chmod 0400 ./strato-auth.json
Run Certbot in manual mode:
sudo certbot certonly --manual --preferred-challenges dns --manual-auth-hook ./auth-hook.py -d example.com -d *.example.com
