History and Evolution
Let’s Encrypt emerged from a collaboration among major technology organizations committed to making encrypted web traffic the default rather than the exception. The Electronic Frontier Foundation, Mozilla Foundation, OVH, Cisco Systems, Facebook, and Google Chrome joined as major sponsors, alongside the Internet Society, AWS, NGINX, and the Bill and Melinda Gates Foundation.
The certificate authority IdenTrust served as a crucial early partner, providing the trust anchor that allowed Let’s Encrypt certificates to be recognized by all major browsers. The University of Michigan and Linux Foundation provided additional institutional support, creating a robust foundation for a service that would fundamentally change how the internet handles encryption.
