How does SSLcat request certificates?

SSLcat uses the ACME (Automated Certificate Management Environment) protocol to automatically request and manage SSL/TLS certificates from Certificate Authorities (CAs) like Let's Encrypt.

ACME Protocol Overview

  1. SSLcat checks the current certificate status upon startup
  2. If needed, it sends a certificate request to Let's Encrypt
  3. Completes the ACME challenge (HTTP-01 or DNS-01)
  4. Let's Encrypt verifies and issues the certificate
  5. SSLcat hot-reloads the certificate
