SSL Certificate Checker vs Silicon Audit

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.

Silicon Audit shows what your Apple device's chip and kernel report about their security features: in plain language first, and in full technical detail when you want it. WHAT IT CHECKS • Memory tagging hardware (MTE) and Apple's Memory Integrity Enforcement • Pointer authentication and branch target protection • Speculation hardening and constant-time execution • The kernel protections Apple documents for your chip family • On macOS, whether memory tagging is active right now, and whether it is active for this app Every answer says where it came from. Measured means your device's kernel reported it through the public sysctl interface. Documented means Apple published it, and the source and date are shown. The app never guesses: a chip Apple has not documented reads as not documented. LOOK DEEPER Every check opens to the facts behind it, and every fact to its raw reading: the sysctl key, type, length and value. All readings sit on three shelves: security protections, chip and instruction sets, device and system. A measurement screen explains how the report was produced. CHANGE MONITORING The first reading becomes a baseline. Silicon Audit checks again when you open it and periodically in the background, and tells you if anything moved: a protection that was reported on and now reports off, a value that changed, a key that appeared or vanished, a system update. Each change is explained at three depths: a plain sentence, what it could mean, and the technical before and after. Notifications are optional. The monitor sees only what the kernel exposes, and the app says so. EXPORT AND CONTRIBUTE Export a JSON report with provenance on every fact. It contains no serial number, device identifier, hostname or account. Contribute it to the public results database on GitHub to help map which Apple chips report which protections. PRIVACY No network access. No analytics. Readings stay on your device unless you share them. Open source under Apache-2.0. Apple Watch: measure on the watch itself and send the report to your iPhone. Apple TV: export as a QR code.
