Certstream-go is a library for interacting with the certstream network to monitor an aggregated feed from a collection of Certificate Transparency Logs.
It leverages the excellent websocket and jsonq libraries and supports reconnecting automatically.
go get github.com/CaliDog/certstream-go
CertStreamEventStream returns two channels, a certificate stream with a JsonQuery structure (which makes working with the JSON returned from CertStream much easier to work with), and an error stream.
package main
import (
"github.com/CaliDog/certstream-go"
logging "github.com/op/go-logging"
)
var log = logging.MustGetLogger("example")
func main() {
// The false flag specifies that we want heartbeat messages.
stream, errStream := certstream.CertStreamEventStream(false)
for {
select {
case jq := <-stream:
messageType, err := jq.String("message_type")
if err != nil{
log.Fatal("Error decoding jq string")
}
log.Info("Message type -> ", messageType)
log.Info("recv: ", jq)
case err := <-errStream:
log.Error(err)
}
}
}The data structure coming from CertStream looks like this:
