A short guide to Log Redactor
Turn noisy input into a usable artifact.
Mask tokens, credentials, cookies, and personal data in logs before sharing them. Here is the practical way to prepare the input, read the output, and decide what to check next.
01
When to reach for it
Scans text for the supported bearer, credential-assignment, private-key, JWT-shaped, and email patterns, then replaces matches with redaction markers. It is most useful when you are dealing with shareable logs or credential in output. Start with the smallest example that still shows the behavior.
- Look for shareable logs, credential in output, PII in logs.
- Reduce the example until one observation can change the result.
02
How to prepare the input
Paste a focused example in application or infrastructure logs. Leave out unrelated noise so the result stays easy to verify.
- Use the accepted format: application or infrastructure logs.
- Keep the facts that make the behavior reproducible.
- Do not treat missing context as a reason to invent an answer.
Example input
Safe sample
2026-08-04 INFO Authorization: Bearer [DEMO_TOKEN] user.email=person@example.invalid password=[REDACTED_SECRET] request_id=abc-123
Run this first to see the shape of the result. Then change one meaningful fact and confirm that the output changes with it.
03
How to read the result
Returns the redacted text and the number of supported sensitive patterns found. Read the finding beside the evidence that produced it. The result narrows the next check; it does not claim to have changed your system.
- Separate the observed fact from the suggested next check.
- Prefer the smallest reversible experiment that can confirm or reject the finding.
- Save the output when it belongs in an incident note, review, or handoff.
04
Know the boundary
Cleaning or decoding changes the presentation of the input; it does not repair the underlying system that produced it.
