  • Zero-Dependency Solution: No external packages required - uses OS commands directly
  • Graceful Fallback: Automatic fallback to environment variables for compatibility
  • Seamless Migration: One-time migration from environment variables to secure storage
  • Cross-Platform Support: Consistent API across macOS, Windows, and Linux

Files Created:

  • packages/core/src/utils/credentialManager.ts - Core secure credential management system with platform-specific storage implementations
  • packages/core/src/utils/credentialMigration.ts - Migration utilities and status reporting for existing users
  • packages/core/src/utils/credentialManager.test.ts - Comprehensive test suite with 30 security test cases

Files Enhanced:

  • packages/cli/src/config/auth.ts - Updated to use secure credential storage with async validation and new credential setters
  • packages/core/src/index.ts - Added credential manager exports for public API

Security Implementation Details:

  • ✅ macOS Keychain: Uses security command for encrypted storage in system keychain

  • Configuration URLs: Base URLs and model names remain in environment variables (non-sensitive)
  • Hybrid Approach: Secure storage first, environment variables as fallback
  • Migration Path: Seamless upgrade from environment-only to secure storage

Enhanced Auth Configuration:

  • Async Validation: All validation functions now properly check secure storage
  • New Credential Setters: API key setters for all providers (OpenAI, Gemini, Anthropic, Grok, RunPod)
