## 3. Generate and use Self-signed Keys and Certificates with MinIO

This section describes how to generate a self-signed certificate using various tools:

* 3.1 [Use certgen to Generate a Certificate](#using-go)

func parseSignedHeader(signedHdrElement string) ([]string, APIErrorCode) {
	signedHdrFields := strings.Split(strings.TrimSpace(signedHdrElement), "=")

For testing purposes, here is [how to create self-signed certificates](https://github.com/minio/minio/tree/master/docs/tls#3-generate-self-signed-certificates).

## 2. Create Kubernetes secret

[Kubernetes secrets](https://kubernetes.io/docs/concepts/configuration/secret) are intended to hold sensitive information.

	// if not return ErrUnsignedHeaders. "host" is mandatory.
