# Let's Encrypt
|
|
|
|
ACME (Automatic Certificate Management Environment) is an open source protocol
|
|
that automates the process of obtaining and renewing SSL/TLS certificates.
|
|
|
|
Let's Encrypt (LE) created this protocol and uses it to issue certificates.
|
|
|
|
Certbot is a popular ACME client that communicates with the LE servers to
|
|
|
|
- validate domain ownership
|
|
- request certificates
|
|
- install the certificates on the web server
|
|
- handle automatic renewals
|
|
|
|
Let's Encrypt was founded by the
|
|
[Internet Security Research Group](https://www.abetterinternet.org/). Certbot
|
|
was created independently by the EFF and is maintained by them.
