Let’s Encrypt 使用 ACME 协议来验证您对给定域名的控制权并向您颁发证书。要获得 Let’s Encrypt 证书，您需要选择一个要使用的 ACME 客户端软件。

下列 ACME 客户端由第三方提供。 Let’s Encrypt 不控制或审查第三方客户端，也不能保证其安全性或可靠性。

您也可以使用某些浏览器（网页版）ACME 客户端，但我们不会在此列出这些客户端，因为它们会鼓励您手动进行续期，从而导致用户体验不佳并增加错过续期的风险。

推荐客户端：Certbot

我们建议大多数人从 Certbot 客户端开始。它既可以只为您获取证书，也可以帮助您获取并安装证书。它易于使用，适用于许多操作系统，并且具有出色的文档。

如果 Certbot 不能满足您的需求，或者您只是想尝试其他软件，那么下面有更多的客户端可供选择，这些客户端按照编写所用的语言或是使用环境排序。

其他客户端

下列客户端均支持 ACMEv2 API (RFC 8555)。 2021 年 6 月起我们已彻底废除 ACMEv1。如果您使用的客户端在该列表中，请确保您将其升级到最新版本。如果下面没有列出您正在使用的客户端，则该客户端有几率不支持ACMEv2 API，请与项目维护者联系或更换其他客户端。

集成了 Let’s Encrypt 的项目

添加客户端/项目

如果您发现某些 ACME 客户端或项目已经集成了 Let’s Encrypt 的 ACMEv2 接口，但本页面尚未列出，请在我们网站的 GitHub 代码仓库中更新 data/clients.json 文件，并发起 Pull Request。

在发起 Pull Request 之前，请确保：

该客户端尊重 Let’s Encrypt 商标政策。
该客户端不是基于浏览器使用的，并且支持自动续期。
该客户端的自动续期时间点是随机的，或鼓励按这种方式配置。
您的提交把该软件加至相关列表的末尾（如果该软件支持 ACMEv2 协议，请不要忘记添加“acme_v2”）。
您的提交更新了 clients.json 顶部的 lastmod 日期戳。
