Engineered a robust automation solution to overcome the limitations of manual SSL maintenance on Namecheap shared hosting. Implemented a "set-and-forget" infrastructure using shell scripting and API hooks to guarantee continuous security compliance and 100% HTTPS uptime. Technical Execution & Key Features Shell Scripting & SSH: Accessed the remote server environment via a restricted shell to install and configure the acme.sh protocol client. API-Driven Deployment: Leveraged the cPanel UAPI deployment hook (cpanel_uapi) to bridge the gap between the certificate authority and the hosting backend. This allows the system to programmatically inject new keys into the server configuration, bypassing manual GUI interactions. Zero-Touch Automation: Established a persistent background schedule (cron) that autonomously performs domain validation, certificate re-issuance, and deployment without human intervention. Multi-Domain Security: Configured webroot authentication to verify and secure both root domains and subdomains (www) simultaneously. Technologies Used: Bash/Shell Scripting, SSH, cPanel API (UAPI), acme.sh, SSL/TLS, Linux Administration.
