Frequently Asked Questions
Are generated passphrases sent over the network?
Never. Passphrases are generated locally using cryptographically secure pseudorandom number generators (CSPRNG).
How does the PII Redactor anonymize text?
It detects credit cards, emails, IP addresses, and phone numbers using local regular expressions and replaces them with clean masks.
Can I print barcodes generated with this tool?
Yes. Barcodes export as crisp vector SVGs or high-resolution PNGs ready for inventory labels and scanners.
