Secret Redactor

Use a copy, not the only evidence

Redaction changes a support artefact. Keep the original in an appropriately restricted location if your incident-handling process needs it. The tool produces a separate result and does not modify the file you selected on disk.

Exact text helps with unusual credentials

A custom credential may not resemble a familiar key format. Add it as an exact literal value to replace every matching occurrence. The optional field is not a regular-expression engine. A short value can also match harmless text, so inspect what changed.

A clean-looking log can still identify a person

Pattern matching cannot recognise every internal hostname, personal identifier, signed URL or encoded secret. It also cannot know whether an ordinary-looking value is confidential in your organisation. Treat the result as a review aid, never proof of anonymisation.

Redacting a leak does not undo it

If a real secret has reached a public issue, shared log or untrusted recipient, remove it where possible and rotate or revoke it through the owning service. A cleaned copy is useful for the next conversation, but it does not invalidate the exposed credential.
