The Automated Certificate Management Environment (ACME) protocol enables automated issuance, renewal, and revocation of SSL/TLS certificates, streamlining certificate lifecycle management. eMudhra’s CERTInext platform supports ACME clients to integrate with web servers, cloud services, and load balancers, ensuring secure and efficient certificate management. This article explores how to use ACME clients with CERTInext, drawing on industry-standard practices and recent advancements in automation.
ACME clients simplify certificate management by automating interactions with Certificate Authorities (CAs) like eMudhra. Benefits include:
Automation: Eliminates manual certificate tasks, reducing errors.
Scalability: Supports high-volume certificate deployments across diverse environments.
Compliance: Ensures certificates meet CA/Browser Forum (CABF) requirements.
Efficiency: Minimizes downtime with seamless renewals, critical for high-traffic systems.
CERTInext is compatible with popular ACME clients, including:
Certbot: Widely used for web servers like Apache and Nginx, offering simple setup and renewal automation.
acme.sh: A lightweight, shell-based client ideal for Linux environments and custom integrations.
Win-ACME: Designed for Windows IIS, integrating with the Windows Certificate Store.
Caddy: A web server with built-in ACME support for automatic HTTPS.
Install the Client: Install your chosen ACME client (e.g., sudo apt install certbot for Certbot on Ubuntu).
Configure CERTInext: Register with eMudhra’s ACME server via the CERTInext dashboard, obtaining an External Account Binding (EAB) key if required.
Issue Certificates: Run a command like certbot certonly --standalone -d example.com or acme.sh --issue -d example.com --webroot /var/www/html to request a certificate, specifying CERTInext’s ACME endpoint (e.g., https://acme.emsign.com/directory).
Automate Renewal: Configure cron jobs or systemd timers (e.g., certbot renew) to check and renew certificates automatically.
Deploy Certificates: Use CERTInext’s integration with Apache, Nginx, or cloud services like AWS Certificate Manager to deploy certificates.
Secure EAB Keys: Store EAB keys securely to prevent unauthorized access.
Monitor Renewals: Use CERTInext’s dashboard to track certificate status and renewal failures.
Test Configurations: Validate ACME workflows in a staging environment to avoid disruptions.
Leverage HTTP-01 or DNS-01: Choose HTTP-01 for web servers or DNS-01 for wildcard certificates, depending on your needs.
ACME clients, combined with CERTInext, enable automated, secure, and scalable certificate management. By integrating clients like Certbot or acme.sh, organizations can streamline SSL/TLS operations.
