Local-first privacy and security tools
NullID groups browser-based privacy and security workflows into one workbench. Sensitive processing happens in your browser session; the application files are delivered from the NullID origin and can be cached for later PWA use.
Remove supported metadata
Inspect image metadata in the browser and clean supported image/PDF metadata with format-specific warnings.
Redact sensitive text
Mask emails, phones, IDs, likely secrets, tokens, and custom local regex matches before sharing text.
Sanitize logs
Apply reusable local policy packs, diff previews, JSON-aware cleaning, and batch text-file sanitization.
Hash and verify
Compute SHA-256, SHA-512, and legacy SHA-1 digests for text or files and compare expected checksums.
Scan likely secrets
Review logs, config snippets, and headers for pattern-based credential findings without uploading content.
Generate passwords
Generate passwords or passphrases locally and create one-way password storage records.
Prepare safe-share packages
Package reviewed text or files with warnings, transform history, and optional encryption.
Verify packages
Inspect received NullID packages, policy packs, snapshots, and envelopes with honest trust labels.
Encryption & secrets
Use encryption, secret scanning, password generation, and Secure Notes when you need to prepare or protect sensitive material without a backend service.

Redaction & sanitization
Use redaction for sensitive text spans and sanitization for repeatable log cleanup policies, diff review, batch text files, and safe-share bundle preparation.
