Monitor PKI Certificates & CRLs for Expiration with Telegram & SMS Alerts

About

PKI Certificate & CRL Monitor - Auto Expiration Alert System Overview This n8n workflow provides automated monitoring of Public Key Infrastructure (PKI) components including CA certificates, Certificate Revocation Lists (CRLs), and associated web services. It extracts certificate information from the TSL (Trusted Service List) -- the Hungarian is the example list as default in the workflow -- , monitors expiration dates, and sends alerts via Telegram and SMS when critical thresholds are reached
