This section describes how to generate a self-signed certificate using various tools:
-* 3.1 [Use generate_cert.go to Generate a Certificate](#using-go)
-* 3.2 [Use OpenSSL to Generate a Certificate](#using-open-ssl)
-* 3.3 [Use OpenSSL (with IP address) to Generate a Certificate](#using-open-ssl-with-ip)

**Note:**
* MinIO only supports keys and certificates in PEM format on Linux and Windows.
* MinIO doesn't currently support PFX certificates.
