What is a Free SSL Certificate? Secure Sockets Layer (SSL) is a security protocol that creates an encrypted link between a web server and a web browser. It ensures that all transferred data remains confidential. You’ve seen a lock icon next to the URL in your address bar when you go to certain sites, right? That means the site is protected by SSL. Most Web providers charge for an SSL certificate but there are a few free sources.
Let’s Encrypt is a free, automated, and open certificate authority brought to you by the nonprofit Internet Security Research Group (ISRG).
Free digital certificates are issued in order to enable HTTPS (SSL/TLS) for websites, for free, to create a more secure and privacy-respecting Web.
The key principles behind Let’s Encrypt are:
- Free: Anyone who owns a domain name can use Let’s Encrypt to obtain a trusted certificate at zero cost.
- Automatic: Software running on a web server can interact with Let’s Encrypt to painlessly obtain a certificate, securely configure it for use, and automatically take care of renewal.
- Secure: Let’s Encrypt will serve as a platform for advancing TLS security best practices, both on the CA side and by helping site operators properly secure their servers.
- Transparent: All certificates issued or revoked will be publicly recorded and available for anyone to inspect.
- Open: The automatic issuance and renewal protocol will be published as an open standard that others can adopt.
- Cooperative: Much like the underlying Internet protocols themselves, Let’s Encrypt is a joint effort to benefit the community, beyond the control of anyone organization.

How It Works
Let’s Encrypt is the first free and open CA. They generate certificates using their ACME server by using domain validation. Private Keys are generated in your browser and never transmitted.
For browsers that support Web Cryptography (all modern browsers) they generate a private key in your browser using the Web Cryptography API and the private key is never transmitted. The private key also gets deleted off your browser after the certificate is generated. If your browser does not support the Web Cryptography API then the keys will be generated on the server using the latest version of OpenSSL and outputted over SSL and never stored. For the best security, you are recommended to use a supported browser for client generation. You can also provide your own CSR when using manual verification in which case the private key is handled completely on your end.
