API Key & Token Redactor: Guide

Scan for secret-looking strings and mask them before sharing (no storage).

What it does

Helps you spot secret-looking strings in logs/config/JSON/curl text (API keys, tokens, Authorization)
Masks risky parts to reduce copy-paste mistakes (manual review still required)
Runs locally in your browser (no server-side storage)

Open the tool 日本語ガイド

Use this when

You want to paste logs to GitHub/Discord/forums and need a quick secrets check
You often forget to remove Authorization: Bearer ... or api_key=...
You need to share parts of .env / config files more safely

Keywords: api key redaction, token masking, secret sanitize, bearer token

How to use

Open the tool
Paste your text
Copy the masked output and share

Tip: quickly scan the final text once before posting.

Notes (limits)

Zero leaks cannot be guaranteed. Always review manually before sharing.
If you exposed a real secret, rotate/revoke the key or token.
This is a detection/masking helper, not a security guarantee.
