func FindPrimaryNsByFqdn

func FindPrimaryNsByFqdn(fqdn string) (string, error)

FindPrimaryNsByFqdn determines the primary nameserver of the zone apex for the given fqdn by recursing up the domain labels until the nameserver returns a SOA record in the answer section.

func FindPrimaryNsByFqdnCustom

func FindPrimaryNsByFqdnCustom(fqdn string, nameservers []string) (string, error)

FindPrimaryNsByFqdnCustom determines the primary nameserver of the zone apex for the given fqdn by recursing up the domain labels until the nameserver returns a SOA record in the answer section.

func FindZoneByFqdn

func FindZoneByFqdn(fqdn string) (string, error)

func FindZoneByFqdnCustom

func FindZoneByFqdnCustom(fqdn string, nameservers []string) (string, error)

FindZoneByFqdnCustom determines the zone apex for the given fqdn by recursing up the domain labels until the nameserver returns a SOA record in the answer section.

func GetRecord

func GetRecord(domain, keyAuth string) (fqdn string, value string)

GetRecord returns a DNS record which will fulfill the `dns-01` challenge.

func ParseNameservers

func ParseNameservers(servers []string) []string

func ToFqdn

func ToFqdn(name string) string

ToFqdn converts the name into a fqdn appending a trailing dot.

func UnFqdn

func UnFqdn(name string) string

UnFqdn converts the fqdn into a name removing the trailing dot.

type Challenge

func (*DNSProviderManual) Sequential

func (d *DNSProviderManual) Sequential() time.Duration

Sequential All DNS challenges for this provider will be resolved sequentially. Returns the interval between each iteration.

type PreCheckFunc

type PreCheckFunc func(fqdn, value string) (bool, error)
