HAR Network Archive Sanitizer — Scrub authorization tokens, cookies & API keys from Chrome DevTools .har files
Sanitize network archives before sending to support teams or third parties. Strips Bearer tokens, Cookie headers, and sensitive query parameters 100% locally in browser memory.
Step-by-Step Client-Side Workflow
1. In-Memory JSON Parsing: Your .har file is parsed directly in browser RAM without uploading megabytes of network logs to external servers.
2. Heuristic Header & Cookie Scrubbing: Replaces sensitive Authorization (Bearer/Basic), Cookie, Set-Cookie, and API token headers with [REDACTED_BY_VAULTTOOLS].
3. Instant Download: Download the clean, scrubbed .har file ready to submit to customer support or bug tracking tickets.
Why Use VaultTools Zero-Upload Architecture
Prevent Account Hijacking: Unscrubbed HAR files contain active session cookies and bearer tokens that allow attackers to impersonate your account.
Safe for Third-Party Vendors: Confidently attach network traces to Zendesk, Jira, or GitHub issues without leaking client credentials.
Zero File Size Limits: Process large 50MB+ network recordings smoothly using streaming browser memory.
Frequently Asked Questions
What is a HAR file and why does it contain sensitive data?
A HAR (HTTP Archive) records all network requests made by your browser, including full request headers, response headers, cookies, and authentication tokens. Sharing raw HAR files can expose your login credentials.
Does this tool inspect or alter the response timing data?
No. Latency, HTTP status codes, and timing metrics remain 100% intact so engineers can still diagnose slow API calls and network bottlenecks.
