Log redactor
Mask emails, tokens, IPs, API keys, and Authorization headers before sharing logs.

Regex redaction can miss secrets; review before sharing.
How to use this tool

Log redactor guide
Workflow and limits
Local rules mask Authorization headers, Bearer tokens, emails, valid IPv4 and api_key=, token=, secret=. Output uses [token], [email], [ip] and [secret], with match counts and a download.
For example ada@example.com becomes [email]. password=, payment cards, national IDs, phone numbers and IPv6 are outside detection scope. Review before sharing; this is not complete anonymization or proof of regulatory compliance.
