What is an Online Text Redactor?

A text redactor is an essential tool for developers, system administrators, and security professionals who need to share logs, configuration files, or code snippets without exposing sensitive information. Our free online text redactor automatically scans your text for common secrets like API keys, passwords, email addresses, credit card numbers, and IP addresses, replacing them with safe placeholder values or cryptographic hashes.

Why Sanitize Log Files?

When debugging complex systems, engineers often need to post log files to public forums like Stack Overflow, GitHub issues, or send them to third-party support teams. These raw logs frequently contain PII (Personally Identifiable Information) or sensitive authentication tokens:

• Authentication Tokens: Exposed JWTs or Bearer tokens can allow attackers to hijack user sessions.
• Cloud Credentials: Accidentally pushing AWS Access Keys or GCP JSON keys can lead to massive financial damage.
• User PII: Leaking customer email addresses, phone numbers, or credit card digits violates GDPR, CCPA, and PCI-DSS compliance.

Failing to redact this data can lead to immediate security breaches. Using our online log redaction tool ensures your diagnostic data is safe to share publicly.

Custom RegEx Pattern Matching

While our tool includes built-in auto-detectors for common secrets (Emails, IPs, Credit Cards, Bearer Tokens), every application has unique data formats. Our free online redactor supports custom Regular Expressions (RegEx), allowing you to define exact patterns for your proprietary user IDs, custom session identifiers, or specialized logging formats. Simply input your regex rule, and the tool will instantly find and mask those specific strings throughout your entire document.
