## What is SSL Certificate Checker?

SSL Certificate Checker helps you monitor SSL/TLS certificate health for the websites and services you care about.

Add one or more targets (hostname + port, default 443), run a check instantly, or scan your whole list in one tap. The app is designed for a quick daily workflow: open, scan, review risk, and act.

What you can check:
- Expiry date and days left
- Status classification: OK, Expiring, Expired, Failed
- Issuer and subject
- SAN (Subject Alternative Name)
- Serial number and signature details
- SHA-256 certificate fingerprint
- SHA-256 public key fingerprint
- Negotiated TLS protocol and cipher suite

Key workflows:
- Single target check for immediate troubleshooting
- Full list scan for regular maintenance
- Saved targets and latest results stored locally on device
- Optional periodic background checks (can be turned on/off)

Built for practical certificate operations:
- Quickly identify certificates close to expiration
- Compare protocol/cipher negotiation outcomes
- Keep a simple watchlist for internal or public endpoints
- Generate and review report-style outputs inside the app

Security perspective for connected-device teams:
- Includes TLS protocol and cipher suite visibility to support baseline security reviews
- Helps teams spot weak or unexpected negotiated ciphers during routine checks
- Useful as an evidence aid for internal security discussions and release readiness
- Designed as a practical checker, not a complete legal/compliance assessment tool

Regulatory context note:
- In the EU, RED cybersecurity delegated requirements under Directive 2014/53/EU Article 3(3)(d)(e)(f) apply from August 1, 2025 for covered products
- This app can support early HTTPS/TLS posture checks, but it does not certify compliance with RED-DA, EN 18031, or any other regulation/standard on its own

Privacy and control:
- No account is required to start checking
- Targets and recent check results are kept locally for your routine usage
- Privacy policy and terms are available from within the app

Current release focus:
- Core SSL/TLS checking flow and result parsing are available
- Batch checking and retry flow are available
- iOS background checks are best-effort (system-scheduled)
- Multilingual UI foundation is integrated; some languages are still being refined

This app is suitable for developers, operators, site owners, and anyone who wants a simple way to track certificate validity and TLS configuration from a mobile device.
