TLS/SSL Inspector

Fetch live TLS chain details for any host — protocol, cipher, and expiry.

Crypto & Certs
Privacy: Server-Assisted. This tool calls /api/* for CORS proxies or TLS inspection. Payloads are not retained.

Uses a server-side TLS socket via /api/ssl — required because browsers cannot expose peer certificates.

What is TLS/SSL Inspector?

TLS/SSL Inspector is part of the stbox.dev developer sandbox. Fetch live TLS chain details for any host — protocol, cipher, and expiry.

It sits in the Crypto & Certs category and is designed for day-to-day debugging, demos, and learning — without forcing you to paste secrets into opaque third-party SaaS forms whenever client-side execution is enough.

How to use this tool

  1. Open TLS/SSL Inspector at https://stbox.dev/ssl-validator and review the privacy badge for runtime expectations.
  2. Paste or configure your input in the tool interface (tokens, URLs, files, or text depending on the utility).
  3. Copy results locally, or chain them into related stbox tools such as JWT, OAuth, or the REST client.

Frequently asked questions

Is my data sent to a server?

TLS/SSL Inspector is hybrid: browser-first where possible, with short-lived server assistance (for example CORS proxies or TLS inspection) processed in memory and not retained as payload logs.

Is stbox free to use?

Yes. Tools are provided as-is for testing and debugging with no account required for core utilities.

Can I use this for production secrets?

Prefer dedicated KMS/HSM workflows for production key material. stbox is optimized for local debugging and education.
