About SSL Checker

The SSL check reads the public certificate presented by a domain and reports details such as issuer, validity period and host coverage. It cannot prove that the website itself is trustworthy or free of application vulnerabilities.

Input

What to prepare

The public URL, domain, IP address, record type, or audit option requested by the checker.

Output

What the result represents

A point-in-time observation from the public target and the checks available on this page.

Typical use

A practical example

A practical way to use it is to run a fresh diagnostic after a hosting, DNS, certificate, redirect, content or performance change. Start with a representative input, inspect the first result, then adjust one setting at a time if you need a different outcome.

  • Investigating a public-site problem with SSL Checker.
  • Verifying a recent configuration change with SSL Checker.
  • Collecting a diagnostic snapshot before troubleshooting with SSL Checker.
Verification

Before you use the result

  • Check that the requested hostname appears in the certificate.
  • Renew well before the displayed expiry date.
  • Investigate chain or hostname errors in the server configuration.
Privacy and processing

The checker uses the public target you enter to make a diagnostic request. Do not place credentials or private access tokens in a URL.
