Local file sanitization for logs and text
The Log Sanitizer applies deterministic text cleanup rules to logs and structured snippets. It is designed for repeatable review before material is copied, downloaded, or packaged.
What it supports
Sanitization supports pasted text, common log presets, JSON-aware cleaning, reusable local policy packs, custom regex rules, policy import/export, batch text-file sanitization, and safe-share bundle export with SHA-256 package metadata.
How to use it
- Choose a preset or import a baseline policy.
- Paste logs or load supported text files.
- Review the before/after diff and rule impact summary.
- Save or export a policy pack when the rules should be reused.
- Run batch mode for multiple text files or export a safe-share bundle.
Not the same as metadata cleanup
Sanitization rewrites text content. Metadata cleanup reviews file metadata and image/PDF outputs. Redaction is better for one-off sensitive spans that need manual masking control.
Limitations
- Rules operate on text; binary files need another workflow.
- Invalid JSON falls back to plain text rule handling.
- Token detection avoids short strings but may miss uncommon credential formats.
- HMAC metadata verifies policy exports only for parties sharing the same passphrase.
