Certificate expiry calendar
Drop as many certificates as you like. PKIScope sorts them by expiry date, shows which have expired or expire soon, and builds a calendar file (.ics) with reminders before each one, ready for Google Calendar, Outlook or Apple Calendar. Nothing is uploaded.
What you can do
- Timeline of expiry dates, soonest first
- Expired and expiring-soon certificates highlighted
- Calendar file (.ics) with reminders 30, 7 and 1 days before expiry
- Works with PEM bundles, DER files and PFX files
- Import into Google Calendar, Outlook or Apple Calendar
Frequently asked questions
How do I add the reminders to my calendar?
Download the .ics file and import it into Google Calendar, Outlook or Apple Calendar. Each certificate becomes an event on its expiry date, with reminders 30, 7 and 1 days before.
Does the calendar update when I renew a certificate?
No. The .ics file is a one-time export of the certificates you dropped. After a renewal, drop the new certificates and import a fresh file.
How do I check one certificate's expiry date with OpenSSL?
Run openssl x509 -enddate -noout -in cert.pem. To see many at once, drop them all here instead.
