SSL Certificate Checker vs SSL检测

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.

SSL评估工具 是面向网站运维、开发者和安全从业者的 SSL/TLS 检测工具。输入域名或 HTTPS URL，即可通过 iPhone 或 iPad 直接检测网站证书与加密配置。 主要功能： • 查看安全等级、域名匹配状态及证书有效期 • 分析证书链、信任状态、SAN、SPKI 指纹与证书扩展 • 检查 OCSP、CRL、证书吊销状态及签名验证结果 • 检测 TLS、SSL、HTTP/2、HTTP/3、QUIC 与密码套件支持 • 评估主流平台和客户端的证书兼容性 • 检查证书透明度及 SCT 日志 • 支持指定 IP + SNI，便于检测特定服务器节点 • 保存检测历史，支持重新检测与结果分享 • 按天或按周监控证书，发现到期、吊销、域名不匹配等异常 • 通过快捷指令执行监控检测并接收异常通知 • 提供 Safari 扩展，可检测当前网页并查看 TLS 证书链 检测由设备直接发起，无需远程评估接口。检测结果与历史记录保存在本机。 适用于证书部署验收、HTTPS 配置排查、证书到期管理及日常网站安全检查。
