SSL expiry checker
Enter a website address to see when its security certificate expires. An expired certificate makes browsers warn visitors away.
The address you enter is sent to our server to run the check. We only read the public certificate.
What this checks
We connect to the site over HTTPS and read the public certificate it presents. Some certificates renew automatically, but it is still worth knowing the date. See also what happens when your hosting plan expires and the domain expiry checker.
