Functions

func GetSupportedAlgorithms

func GetSupportedAlgorithms() []string

Returns a slice of all the supported algorithms It should contain all listed in https://tools.ietf.org/html/rfc4635#section-2 but miekd/dns supports only supportedAlgorithms(keys)

func ValidNameserver

func ValidNameserver(nameserver string) (string, error)

func NewDNSProviderCredentials

func NewDNSProviderCredentials(nameserver, tsigAlgorithm, tsigKeyName, tsigSecret string) (*DNSProvider, error)

func (*DNSProvider) CleanUp

func (r *DNSProvider) CleanUp(domain, token, keyAuth string) error

CleanUp removes the TXT record matching the specified parameters

func (*DNSProvider) Present

func (r *DNSProvider) Present(domain, token, keyAuth string) error
