Generate browser-trusted SSL certificates for any domain you own with Personal SSL Certificate — a Let's Encrypt ACME client that runs entirely on your Windows PC. No public IP needed, no port forwarding, one DNS TXT record, and you hold a valid X.509 certificate for your domain — complete with a 90-day validity window and one-click renewals. Everything runs locally on your device with no external cloud dependencies. ONE DOMAIN, ONE CERTIFICATE Every site you host requires trusted HTTPS encryption: yourdomain.com, accepted across all modern web browsers and mobile operating systems. Personal SSL Certificate streamlines the ACME protocol and automated DNS-01 validation into a clean, guided 3-step setup flow. HOW IT WORKS 1. Enter your domain and contact email — the app manages your ACME account registration directly with Let's Encrypt. 2. The app initiates the certificate order and generates the exact DNS TXT record required for validation. 3. Add the TXT record at your DNS provider (compatible with Cloudflare, Namecheap, GoDaddy, Route 53, and all standard DNS registrars). 4. The built-in DNS propagation monitor detects when the record is live, completes the challenge, and retrieves your issued certificate. 5. Save your certificate and private key in universal PEM format, ready for immediate deployment to your server or proxy.
