What is Let’s Encrypt?

Let’s Encrypt is a non-profit certificate authority that provides free SSL/TLS certificates to website owners. These certificates enable secure communication by encrypting data transmitted between a user’s browser and the web server, ensuring privacy and protecting against malicious attacks.

Website security is crucial in today’s digital world. An SSL/TLS certificate plays a vital role by encrypting communication between servers and browsers. Let’s Encrypt revolutionized certificate authorities with its free, automated SSL/TLS certificates. In this blog post, we’ll explore Let’s Encrypt certificates, their purpose, functionality, and impact on website security.

How does Let’s Encrypt Certificates Work?

Let’s Encrypt employs an automated certificate management protocol called ACME (Automatic Certificate Management Environment). ACME streamlines the process of obtaining, renewing, and revoking SSL/TLS certificates. With ACME, the certificate issuance and renewal process becomes seamless and hassle-free. Here, some step-by-step explanation of how Let’s Encrypt works:

  • Requesting a Certificate:

The website owner begins by requesting a certificate from Let’s Encrypt. They provide information about the domain name and other required details to initiate the process.
