x509 error on Kobo

[roedesh]

I am currently working on a homebrew app for the Kobo Libra H20. Whenever I try to make a web request, I get a x509 error. Something to do with certificate validation apparently.

My app is written in Go. In order to successfully make a web request, I need to do this:

func GetHttpClient() *http.Client {
	transport := &http.Transport{
		TLSClientConfig: &tls.Config{InsecureSkipVerify: true},
	}

	return &http.Client{
		Timeout:   time.Second * 5,
		Transport: transport,
	}
}

But this completely disables certificate validation, which makes you susceptible to man-in-the-middle attacks. So I was wondering if there is a better way to solve this issue?

You will have to integrate certificates into the Kobo device with your app.
I've managed that in KoboMail by bundling the certificates and then placing them where Go looks for them:

The file is got from here: https://curl.se/docs/caextract.html

Hope this helps.

Thanks, that did the trick!
