Functions ¶

func AddRelayTransport ¶

func AddRelayTransport(p *DcMulti, relaystamp string) error

AddRelayTransport creates and adds a relay server to p

func AddTransport ¶

func AddTransport(p *DcMulti, id, serverstamp string) (*severbyid, error)

AddTransport creates and adds a dnscrypt transport to p

func NewTransport ¶

func NewTransport(p *DcMulti, id, rawstamp string) (dnsx.Transport, error)

NewTransport creates a free-standing (unregistered) DNSCrypt transport for id from rawstamp (a sdns:// stamp), dialing via p's proxies. The returned transport is not registered with p nor tracked by any resolver, and its certificate is not refreshed; it is expected to be short-lived (as long as the fetched certificate remains valid).
