## 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)

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.

Beispielsweise verwendet der Google Login OpenID Connect (welches seinerseits OAuth2 verwendet).

Aber der Facebook Login unterstützt OpenID Connect nicht. Es hat seine eigene Variante von OAuth2.

### OpenID (nicht „OpenID Connect“)

Es gab auch eine „OpenID“-Spezifikation. Sie versuchte das Gleiche zu lösen wie **OpenID Connect**, basierte aber nicht auf OAuth2.
