Let's Encrypt is a free, automated, and open certificate authority (CA), run by the Internet Security Research Group (ISRG). Let's Encrypt issues certificates for Transport Layer Security (TLS) encryption at no charge. This is an important service because it allows website operators to secure their sites with HTTPS without having to pay for a certificate.
HTTPS is important because it provides a number of security and privacy benefits. When you connect to a site with HTTPS, your connection is encrypted and your data is protected from eavesdroppers. This makes it much harder for someone to intercept your data or impersonate the site you're connecting to.
Let's Encrypt is a CA that issues certificates using the Automatic Certificate Management Environment (ACME) protocol. ACME is a protocol for automatically verifying that a site is correctly configured and for issuing certificates.
To get a certificate from Let's Encrypt, you need to prove to the CA that you control the domain you're requesting a certificate for. There are a number of ways to do this, but the most common is to use the DNS challenge. With the DNS challenge, you create a DNS record that proves you control the domain. Once you've done this, Let's Encrypt will issue you a certificate.
Let's Encrypt certificates are valid for 90 days. To keep your certificate up-to-date, you can renew it automatically using a tool like certbot.

What is Letsencrypt used for?
Letsencrypt is a free, automated, and open Certificate Authority (CA), run by the Internet Security Research Group (ISRG). It provides a way for website owners to obtain valid SSL/TLS certificates without having to go through the traditional, expensive process of verification by a trusted CA.
Letsencrypt issues certificates that are valid for 90 days, after which they can be renewed automatically. This makes it much easier for website owners to keep their sites up-to-date with the latest security best practices.
Letsencrypt is supported by a wide range of web browsers, including all major browsers such as Chrome, Firefox, Safari, and Edge.
Why is let's encrypt only 3 months?
The security of Let's Encrypt certificates relies on the fact that they are short-lived. If a certificate were valid for a year or more, an attacker who obtained control of a domain could issue a new certificate for that domain and use it to intercept traffic or impersonate the site. By renewing certificates frequently, we can reduce the window of opportunity for an attacker.
Let's Encrypt certificates are valid for 90 days. We believe this is a good balance between security and convenience. For most websites, renewing a certificate every 90 days will not be a significant burden. If you need more frequent renewals, you can use our automated certificate management tools. Is Let's encrypt SSL free? Yes, Let's Encrypt SSL is free. There are no setup fees or monthly charges. You can use Let's Encrypt to secure any number of websites or other Internet-accessible resources without spending any money.
Why shouldn't you use lets Encrypt?
There are a few reasons why you might not want to use Let's Encrypt for your website or web application.
First, Let's Encrypt is a relatively new Certificate Authority (CA), and as such, some browsers and devices may not yet trust certificates issued by Let's Encrypt. This means that visitors to your site may see warnings that the site is not secure.
Second, Let's Encrypt certificates are only valid for 90 days. This means that you will need to renew your certificate more often than with other CAs.
Third, Let's Encrypt does not offer wildcard certificates. This means that you will need to have a separate certificate for each subdomain of your site.
Finally, Let's Encrypt is not yet as widely supported as some other CAs. This means that you may have difficulty using some features that require a certificate, such as certain email encryption features.
What happened to Letsencrypt?
Letsencrypt is a free, open source certificate authority (CA) that provides free SSL/TLS certificates. It was created in response to the growing need for web security, and to make it easier for website owners to get and maintain SSL/TLS certificates.
Letsencrypt's certificates are valid for 90 days, and they can be automatically renewed. However, if a website's configuration changes, the certificate may need to be manually renewed.
Letsencrypt has been acquired by Internet Security Research Group (ISRG), a nonprofit organization. ISRG plans to continue to operate Letsencrypt as a free and open CA.
