SSL Certificate Checker

Inspect any site's TLS/SSL certificate and see the details that matter: who issued it, when it became valid, when it expires, how many days are left and whether it has already lapsed. It is the fastest way to confirm a site's encryption is healthy.

What the SSL checker does

This tool connects to a website and reads the TLS certificate it presents, then reports the essentials in plain language. You get the issuer that signed the certificate, the valid-from date it took effect, the valid-to date it expires, a clear count of the days until expiry, and a direct answer to whether the certificate is expired right now. No guesswork, no digging through browser menus, just the facts about the padlock.

How to use it

  • Enter a domain or full URL, for example example.com.
  • Read the issuer to confirm the certificate comes from a trusted authority.
  • Check the valid-to date and the days remaining to plan renewal.
  • Watch for an expired flag, which means visitors are seeing security warnings.

The check runs live against the site, so the certificate you see is the one being served to real visitors at that moment.

Why it matters

An expired or misconfigured certificate is one of the most damaging problems a website can have. Browsers throw full-page security warnings, visitors bounce, and trust evaporates in seconds. Certificates typically last only a few months, so an unnoticed expiry is a common cause of sudden outages. Checking the days remaining lets you renew ahead of time instead of scrambling after the fact. Confirming the issuer helps you spot certificates that are self-signed or issued by an unexpected authority. At Digzy Technology, our team in Bali, Indonesia monitors certificate expiry on the sites we build so a lapsed certificate never takes a client offline. Whether you run one site or many, a quick check keeps your encryption valid and your visitors confident.

FAQ

Frequently asked questions

How often should I check my SSL certificate?
Since many certificates renew automatically every 90 days, a periodic check is smart to confirm the renewal actually happened. Checking monthly, or right after any hosting change, catches problems early.
What happens when an SSL certificate expires?
Visitors see a browser security warning and many will leave immediately. Search rankings and conversions can suffer, so it is important to renew before the valid-to date passes.
What does the issuer tell me?
The issuer is the certificate authority that signed the certificate. Recognized authorities are trusted by browsers, while a self-signed or unknown issuer will trigger warnings.
Why does my certificate show as valid in the browser but I want to double check?
Browsers cache and sometimes tolerate edge cases. A direct live check reads the certificate as served and gives you an exact days-until-expiry figure so nothing slips by.
