API Key & Token Redactor

The API Key & Token Redactor automatically identifies and securely redacts sensitive credentials from text content. It supports multiple redaction modes and recognizes a wide range of API keys and tokens from popular services.

API Key & Token Redactor Architecture

Token detection and redaction workflow

Security Notice: Always handle sensitive credentials with care. This tool helps prevent accidental exposure but should be part of a comprehensive security strategy.

Supported Credentials

  • AWS Access Keys
  • GitHub Tokens
  • GitLab Tokens
  • Discord Tokens
  • Slack Tokens
  • OpenAI API Keys
  • Google Cloud Keys
  • Stripe Keys
  • Twitter API Keys
  • Facebook Tokens
  • LinkedIn API Keys
  • JWT Tokens
  • SSH/RSA Keys
  • Database Credentials
  • OAuth Tokens
  • Custom Patterns

Redaction Modes

  • Partial:

    Preserves the first and last few characters while masking the middle portion (e.g., "abc...xyz")

  • Full:

    Replaces the entire credential with a placeholder (e.g., "[REDACTED]")

  • Hash:

    Replaces the credential with its cryptographic hash for tracking

Configuration Options

  • mode: Redaction mode selection
  • patterns: Custom regex patterns
  • placeholder: Custom redaction text
  • hash_function: Hash algorithm selection

Example Output Formats

Original:

API_KEY=sk-1234567890abcdef

Partial Redaction:

API_KEY=sk-12...def

Full Redaction:

API_KEY=[REDACTED]

Hash Redaction:

API_KEY=a1b2c3d4e5f6...

Use Cases

  • Log file sanitization
  • API documentation
  • Error reporting
  • Support ticket systems
  • Code repositories
  • Chat applications

Note: Regular expressions are continuously updated to match new API key formats. Consider implementing automated updates to maintain detection accuracy.

Tip: Test the redactor with sample data containing known patterns to verify detection accuracy. Consider using different redaction modes for different security requirements.
