The ACME server will need to verify that you are the owner of the domain
names that you are requesting the certificate for. This happens both during
initial setup and for every future renewal. There are two main methods of
doing so: answering specific http requests (http-01) or create specific dns
records (dns-01). For wildcard domains the latter is the only option. Various
additional plugins are available from https://github.com/win-acme/win-acme/.

1: [http-01] Save verification files on (network) path
2: [http-01] Serve verification files from memory
3: [http-01] Upload verification files via FTP(S)
4: [http-01] Upload verification files via SSH-FTP
5: [http-01] Upload verification files via WebDav
6: [dns-01] Create verification records manually (auto-renew not possible)
7: [dns-01] Create verification records with acme-dns (https://github.com/joohoi/acme-dns)
8: [dns-01] Create verification records with your own script
9: [tls-alpn-01] Answer TLS verification request from win-acme
C: Abort

How would you like prove ownership for the domain(s)?: 1
