It is not very popular or used nowadays.

OAuth2 doesn't specify how to encrypt the communication, it expects you to have your application served with HTTPS.

/// tip

In the section about **deployment** you will see how to set up HTTPS for free, using Traefik and Let's Encrypt.

## Let's Encrypt

Avant Let's Encrypt, ces certificats HTTPS étaient vendus par des tiers de confiance.

Le processus d'acquisition d'un de ces certificats était auparavant lourd, nécessitait pas mal de paperasses et les certificats étaient assez chers.

Mais ensuite, <a href="https://letsencrypt.org/" class="external-link" target="_blank">Let's Encrypt</a> a été créé.

    @CsvSource({ "true, true, SMB311, 2", // DFS + Encryption
            "false, true, SMB311, 1", // Encryption only
            "true, false, SMB311, 1", // DFS only
            "false, false, SMB311, 0", // Neither
            "true, true, SMB210, 1", // DFS only (no encryption for SMB2)
            "false, true, SMB210, 0" // Neither (no encryption for SMB2)
    })

## Let's Encrypt { #lets-encrypt }

Antes de Let's Encrypt, estos **certificados HTTPS** eran vendidos por terceros.

El proceso para adquirir uno de estos certificados solía ser complicado, requerir bastante papeleo y los certificados eran bastante costosos.

Pero luego se creó **<a href="https://letsencrypt.org/" class="external-link" target="_blank">Let's Encrypt</a>**.

        // Then
        assertNotNull(encKey, "Encryption key should not be null");
        assertEquals(16, encKey.length, "Encryption key should be 16 bytes");
        assertFalse(Arrays.equals(sessionKey, encKey), "Encryption key should be different from session key");
    }

    @Test
    @DisplayName("Should derive different encryption keys for different dialects")

你可以用作 TLS 终止代理的一些选项包括：

* Traefik（也可以处理证书更新）
* Caddy（也可以处理证书更新）
* Nginx
* HAProxy

## Let's Encrypt

在 Let's Encrypt 之前，这些 **HTTPS 证书** 由受信任的第三方出售。

过去，获得这些证书的过程非常繁琐，需要大量的文书工作，而且证书非常昂贵。

但随后 **<a href="https://letsencrypt.org/" class="external-link" target="_blank">Let's Encrypt</a>** 创建了。

它是 Linux 基金会的一个项目。 它以自动方式免费提供 **HTTPS 证书**。 这些证书可以使用所有符合标准的安全加密，并且有效期很短（大约 3 个月），因此**安全性实际上更好**，因为它们的生命周期缩短了。
