This service is provided by the Internet Security Research Group (ISRG). The objective of Let’s Encrypt is to set up a HTTPS server and make it obtain a browser-trusted certificate automatically, without any human intervention.

Let’s Encrypt certificate authority provides SSL certificates for Transport Layer Security (TLS) encryption by an automated process.

How an SSL secures an e-commerce transaction works?

Whenever a visitor shares his/her information and credit card details with a website, the visitor’s browser asks the website to provide its SSL certificate for establishing a secure connection.

When the server provides it to the browser, it identifies the Certificate Authority(CA) who issues the SSL certificate and confirms if the certificate is valid. With SSL, the information is encrypted and shared in case of a valid certificate, thereby securing the customer crucial details during transaction.

How does Let’s Encrypt work?

Let’s Encrypt recognizes the server admin by public key. A key pair is generated when the agent software interacts with Let’s Encrypt for the first time. The agent needs to sign up with key pair to prove that it controls the key pair. If the agent successfully signs up, a file is created on a specified path on the site. The agent must sign the provided nonce with its private key. When these steps are completed, the Certificate Authority is notified that it is ready to complete validation.

The CA than verifies the signature on the nonce and downloads the file from web server and checks it if it has the expected content and the request is authorized. Let’s Encrypt is compatible with most of the web browsers.

The Let’s Encrypt certificate can be obtained by anyone at zero cost who owns a domain name. If you are looking for making your online presence, you can get a domain name along with web or cloud hosting services by any reliable web hosting provider.
