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

До появления Let's Encrypt эти **HTTPS-сертификаты** продавались доверенными третьими сторонами.

Процесс получения таких сертификатов был неудобным, требовал бумажной волокиты, а сами сертификаты были довольно дорогими.

Затем появился **<a href="https://letsencrypt.org/" class="external-link" target="_blank">Let's Encrypt</a>**.

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.

///

## OpenID Connect { #openid-connect }

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。
