How to Safely Redact API Keys and Sensitive PII from Server Logs
Developers frequently copy-paste stack traces, crash dumps, and HTTP debug logs into ChatGPT, Claude, GitHub Issues, or Slack. Unfortunately, those logs often contain live API keys, Bearer JWT tokens, user email addresses, and internal IP addresses.
Why does this problem happen?
Debug loggers and environment dumps serialize HTTP headers, database connection strings, and request payloads verbatim. Manually hunting for every sk- key, ghp_ token, or email address in a 500-line log file is slow and error-prone.
Once a secret is pasted into a third-party cloud tool or public issue, it can be stored in prompt history or indexed, forcing emergency key rotation.
How to solve it?
Paste your raw log or JSON payload into the editor above with Sensitive Data Masking enabled. DataPurge scans for common secret patterns (OpenAI keys, GitHub tokens, AWS access keys, Bearer JWTs, emails, and IPv4s) and replaces them with safe [REDACTED_*] placeholders.
You can then safely copy the sanitized log for debugging, AI prompting, or incident reports.
Why use 100% Client-Side (Zero-Telemetry)?
Uploading unredacted logs containing live API keys to a server-side redaction website defeats the entire purpose of redacting them.
DataPurge runs every regex scan exclusively inside your browser tab with zero network requests, keeping your secrets strictly on your machine.
