// TRANSACTION SIGNATURE
//
// An TSIG or transaction signature adds a HMAC TSIG record to each message sent.
// The supported algorithms include: HmacMD5, HmacSHA1 and HmacSHA256.
//
// Basic use pattern when querying with a TSIG name "axfr." (note that these key names
// must be fully qualified - as they are domain names) and the base64 secret
// "so6ZGir4GPAqINNh9U5c3A==":
//
// c := new(dns.Client)
// c.TsigSecret = map[string]string{"axfr.": "so6ZGir4GPAqINNh9U5c3A=="}
// m := new(dns.Msg)
// m.SetQuestion("miek.nl.", dns.TypeMX)
// m.SetTsig("axfr.", dns.HmacMD5, 300, time.Now().Unix())
// ...
// // When sending the TSIG RR is calculated and filled in before sending
//
// When requesting an zone transfer (almost all TSIG usage is when requesting zone transfers), with
// TSIG, this is the basic use pattern. In this example we request an AXFR for
// miek.nl. with TSIG key named "axfr." and secret "so6ZGir4GPAqINNh9U5c3A=="
// and using the server 176.58.119.54:
//
// t := new(dns.Transfer)
// m := new(dns.Msg)
// t.TsigSecret = map[string]string{"axfr.": "so6ZGir4GPAqINNh9U5c3A=="}
// m.SetAxfr("miek.nl.")
// m.SetTsig("axfr.", dns.HmacMD5, 300, time.Now().Unix())
// c, err := t.In(m, "176.58.119.54:53")
// for r := range c { /* r.RR */ }
//
// You can now read the records from the transfer as they come in. Each envelope is checked with TSIG.
// If something is not correct an error is returned.
//
// Basic use pattern validating and replying to a message that has TSIG set.
//
// server := &dns.Server{Addr: ":53", Net: "udp"}
// server.TsigSecret = map[string]string{"axfr.": "so6ZGir4GPAqINNh9U5c3A=="}
// go server.ListenAndServe()
// dns.HandleFunc(".", handleRequest)
//
// func handleRequest(w dns.ResponseWriter, r *dns.Msg) {
// m := new(Msg)
// m.SetReply(r)
// if r.IsTsig() {
// if w.TsigStatus() == nil {
// // *Msg r has an TSIG record and it was validated
// m.SetTsig("axfr.", dns.HmacMD5, 300, time.Now().Unix())
// } else {
// // *Msg r has an TSIG records and it was not valided
// }
// }
// w.WriteMsg(m)
// }
