## Let's Encrypt { #lets-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 **[Let's Encrypt](https://letsencrypt.org/)** 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。

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.
