What does an SSL checker do?
It connects to a website over HTTPS and reads its certificate, to make sure it is trusted, matches the domain and has not expired.
Website Tools
SSL Checker
Check any website SSL certificate: expiry date, issuer, domains covered and chain.
How it works
1
Enter a domain
Type the domain, like example.com.
2
Run the check
Craftora connects to the site over HTTPS, the same way a browser does.
3
Read the result
See whether it is trusted, the days left, the issuer, the domains covered and the chain.
SSL Checker features
- Valid or not, with the exact reason browsers would complain.
- Days left before the certificate expires.
- Issuer, like Let's Encrypt, Google or DigiCert.
- All domain names the certificate covers.
- TLS version, cipher and key type.
- Full certificate chain.
SSL Checker FAQ
Why does my site show "not secure"?
The certificate may be expired, issued for a different name, or missing a middle (intermediate) certificate. The checker shows which one.
How often should I renew?
Most certificates last 90 days to a year. Free Let's Encrypt certificates renew every 90 days, usually by themselves.
Is the check safe?
Yes. It only reads the public certificate the site sends to every visitor.
