What's New

Sensitive Field Masking

Added support for masking sensitive fields in request/response body logs using regex patterns.

Usage:

r.Use(tlog.GinMiddleware(
    tlog.WithMaskPatterns(
        `(?i)password`,      // matches "password", "Password", "PASSWORD"
        `(?i)secret`,        // matches "secret", "Secret", etc.
        `(?i)token`,         // matches "token", "accessToken", etc.
        `(?i)api[_-]?key`,   // matches "api_key", "apiKey", "API-KEY"
    ),
))

Features:

  • Regex patterns for flexible field name matching
  • Recursively masks nested objects and arrays
  • Only applies to JSON bodies (non-JSON unchanged)
  • No performance impact when no patterns configured
  • Applied to both request and response bodies

Example:

// Before
{"username": "john", "password": "secret123", "data": {"api_key": "xyz"}}

// After (logged)
{"username": "john", "password": "******", "data": {"api_key": "******"}}
