About this app

Certificate Viewer helps you inspect a server’s TLS/SSL certificate directly from your Android device. Enter a hostname, URL, or IP address and optional port to retrieve a clear certificate report. Quickly understand whether a certificate is valid, trusted by Android, and matched to the requested hostname.

The report includes:
• Certificate expiration date and days remaining
• Subject and issuer details
• Subject Alternative Names (SANs)
• Hostname-match status
• Android trust result and date validity
• TLS version and negotiated cipher suite
• Public-key and signature algorithms
• Certificate-chain length
• Server IP address
• SHA-256 certificate fingerprint
• Serial number

Use Certificate Viewer to troubleshoot HTTPS connections, verify certificate deployments, compare certificate details, or share a report with your team.

Inspect TLS/SSL certificates: expiry, trust, hostname, fingerprints & more.
