What is an ACME client and why do I need it?
ACME stands for Automated Certificate Management Environment, and it's a protocol for automating the interactions required between your server and the certificate authority for SSL certificates.
An ACME client is a handy tool that takes the hassle out of managing SSL/TLS certificates. It automatically handles getting, renewing, and revoking certificates by talking directly to a Certificate Authority (CA) server through the ACME protocol. The client lives on your server and proves you own your domain by completing simple challenges, like adding a specific file or DNS record. Once verified, you get secure certificates for HTTPS and other services. You can use standalone tools like Certbot or integrate ACME clients right into your web server or hosting platform.
