SSL Lookup
SSL Lookup – Check SSL Certificate Details for Any Website
SSL Lookup is a tool for checking and verifying SSL certificates. It is used by a website. It includes critical information such as the certificate type, expiration date, issuer name, etc. With an SSL certificate lookup, you can instantly determine your website's security. That website is safe and secure for visitors.
This utility is sometimes called SSL cert lookup. Also, we can say SSL certificate lookup, or certificate lookup SSL. It is widely used by web developers, IT administrators, and digital security professionals to track and manage SSL data.
What Is an SSL Certificate?
SSL, sometimes known as Secure Sockets Layer, certificates are digital. That encrypts data moving between a website's user and the server. It provides safe communication, particularly in cases when users reveal passwords, credit card information, or private data.
A website using SSL will start with HTTPS instead of HTTP. The address bar of the browser will also show a padlock icon, seen by every visitor.
What Is an SSL Lookup?
An SSL lookup tool provides extensive information on a website's SSL certificate. You simply enter the website URL, and the program returns the certificate data in seconds.
You can use SSL lookup tools to:
- Confirm that a website has a valid certificate
- Check certificate issue and expiry dates
- See which Certificate Authority (CA) issued the certificate
- Identify the type of certificate (DV, OV, EV)
- View the SSL serial number and signature
- Check which domains the certificate is covering
- Detect any security problems like mismatched names or expired certificates
Benefits of Using SSL Certificate Lookup
1. Verify Website Security
You can confirm if a website is properly secured by using an SSL certificate lookup tool. If a certificate is expired or not trusted, it may put visitors at risk.
2. Track SSL Expiry Dates
Using an SSL certificate lookup tool helps website owners keep track of certificate expiry dates. This prevents unexpected downtimes due to expired certificates.
3. Troubleshoot SSL Issues
If your website shows security warnings, a certificate lookup SSL tool can help you find the issue, whether it’s an expired certificate, wrong domain, or untrusted CA.
4. Check for Shared Certificates
You can use SSL cert lookup to check if a certificate is shared across multiple domains. This is common in shared hosting environments.
Lookup SSL Certificate Information in Detail
When you run an SSL lookup, you’ll receive:
| SSL Detail | Description |
|---|---|
| Common Name (CN) | The primary domain the certificate is issued for |
| Subject Alternative Names (SANs) | Other domains/subdomains covered by the certificate |
| Issuer | The Certificate Authority that issued the certificate |
| Issue and Expiry Dates | When the certificate started and when it will expire |
| SSL Certificate Serial Number | A unique identifier for the certificate |
| Signature Algorithm | The method used to digitally sign the certificate |
| SSL Chain Details | Intermediate and root certificates linked to the main certificate |
| Public Key Details | Information used to encrypt and verify data |
| Validation Level | DV (Domain Validation), OV (Organization Validation), or EV (Extended Validation) |
| Revocation Status | Check if the certificate has been revoked by the CA |
SSL Certificate Serial Number Lookup
The Certificate Authority grants every SSL certificate a distinct serial number. SSL certificate serial number lookup, sometimes known as SSL serial number search, lets you find a certain certificate. It authenticates its authenticity and tracks associated information. This is helpful for:
- Detecting duplicate certificates
- Managing large-scale SSL deployments
- Verifying revoked or suspicious certificates
Whois SSL Lookup
A Whois SSL lookup provides additional details about the organization or individual who owns the SSL certificate. This includes:
- Owner or business name
- Certificate registration date
- Technical contact information (if public)
- Organization validation (for OV or EV certificates)
This information is useful when you need to confirm a website’s ownership or legitimacy, especially for business websites.
