src/cmd/go.mod. When a package outside std or cmd is imported
by a package inside std or cmd, the import path is interpreted
as if it had a "vendor/" prefix. For example, within "crypto/tls",
an import of "golang.org/x/crypto/cryptobyte" resolves to
"vendor/golang.org/x/crypto/cryptobyte". When a package with the
same path is imported from a package outside std or cmd, it will

 *   <li>isImplicit: Whether to use implicit SSL/TLS encryption.</li>
 *   <li>trustManager: The trust manager to use for SSL/TLS connections ("all", "valid", or "none").</li>

We also saw that HTTPS is normally provided by a component **external** to your application server, a **TLS Termination Proxy**.

And there has to be something in charge of **renewing the HTTPS certificates**, it could be the same component or it could be something different.

### Example Tools for HTTPS { #example-tools-for-https }

Some of the tools you could use as a TLS Termination Proxy are:

* Traefik
    * Automatically handles certificates renewals ✨

pkg crypto/sha512, func Sum512_256([]uint8) [32]uint8
pkg crypto/tls, const TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384 = 49196
pkg crypto/tls, const TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384 uint16
pkg crypto/tls, const TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 = 49200
pkg crypto/tls, const TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 uint16
pkg crypto/tls, method (*Config) SetSessionTicketKeys([][32]uint8)
pkg crypto/tls, type Certificate struct, SignedCertificateTimestamps [][]uint8

   * certificates.

      throws NoSuchAlgorithmException, KeyManagementException {
    SSLContext sslContext = SSLContext.getInstance("TLS");
    sslContext.init(null, new TrustManager[] { trustManager }, null);

    return sslContext.getSocketFactory();
  }

You may also setup etcd with TLS following this documentation [here](https://coreos.com/etcd/docs/latest/op-guide/security.html)

### 3. Setup MinIO with etcd
