如何使用Let's Encrypt在WordPress中添加免费SSL

When we first covered how to add SSL in WordPress, a lot of our readers asked for a free SSL solution. Unfortunately nothing existed at that time. However that has changed now thanks to Let’s Encrypt. In this article, we will show you how to add free SSL in WordPress with Let’s Encrypt.

当我们第一次介绍如何在WordPress中添加SSL时 ，许多读者都要求提供免费的SSL解决方案。 不幸的是，当时不存在任何东西。 但是，现在有了改变，这要归功于Let's Encrypt。 在本文中，我们将向您展示如何使用Let's Encrypt在WordPress中添加免费的SSL。

什么是SSL和加密？ (What is SSL and Let’s Encrypt?)

Every internet user shares lots of personal information each day. We do that when shopping online, creating accounts, signing into different websites, etc.

每个互联网用户每天都共享大量个人信息。 我们在网上购物，创建帐户，登录其他网站等时会这样做。

If not properly encrypted, then this information can be spied upon and stolen. This is where SSL comes in. It provides the encryption technology to secure the connection between a user’s browser and the web server.

如果未正确加密，则该信息可能会被窃取和窃取。 这就是SSL的用武之地。它提供了加密技术来保护用户浏览器和Web服务器之间的连接。

Each site is issued a unique SSL certificate for identification purposes. If a server is pretending to be on HTTPS, and it’s certificate doesn’t match, then most modern browsers will warn the user from connecting to the site.

每个站点都会获得一个唯一的SSL证书以用于识别。 如果服务器假装使用HTTPS，并且其证书不匹配，则大多数现代浏览器都会警告用户不要连接到该站点。

Previously, the only way to secure sites with SSL was by using a paid SSL certificate.

以前，使用SSL保护网站的唯一方法是使用付费SSL证书 。

Let’s Encrypt is a free open certificate authority that aims to provide SSL certificate for general public. It is a project of Internet Research Group, a public service corporation. Let’s Encrypt is sponsored by many companies including Google, Facebook, Sucuri, Mozilla, Cisco, etc.

让我们加密是一个免费的开放证书颁发机构，旨在为普通大众提供SSL证书。 它是公共服务公司Internet Research Group的一个项目。 Let's Encrypt由许多公司赞助，包括Google，Facebook， Sucuri ，Mozilla，Cisco等。

Having said that, let’s take a look at how you can add free SSL certificate to your WordPress site with Let’s Encrypt.

https://www.example.com

Without changing the URLs in your WordPress site, you will not be using SSL and your site will not be secure for collecting sensitive data.
