SSL Lookup
What Is an SSL Lookup Tool?
An SSL Lookup tool helps you inspect the SSL/TLS certificate presented by a website. These certificates help authenticate a website's identity and enable encrypted connections between browsers and servers.
Rankcept's SSL Lookup tool can help you review available certificate information for a domain.
How to Check an SSL Certificate
- Enter the website's domain name.
- Submit the lookup request.
- Review the certificate information returned by the tool.
The results depend on the certificate presented by the server and the information the tool can retrieve.
What Information Can an SSL Lookup Show?
Depending on the lookup service, certificate details may include:
- Issuer: The certificate authority that issued the certificate.
- Validity dates: The certificate's start and expiration dates.
- Subject and domain names: The identity information included in the certificate.
- Certificate status: Available information about whether the certificate is valid or has relevant problems.
- Certificate details: Additional technical information supported by the lookup service.
Why Should You Check an SSL Certificate?
Checking a certificate can help website owners identify expiration dates, review certificate configuration, and investigate browser security warnings.
A certificate lookup alone does not guarantee that a website is completely secure. Website security also depends on server configuration, application security, and other factors.
