fix(#84): address critical security issues in federation identity
Implemented comprehensive security fixes for federation instance identity: CRITICAL SECURITY FIXES: 1. Private Key Encryption at Rest (AES-256-GCM) - Implemented CryptoService with AES-256-GCM encryption - Private keys encrypted before database storage - Decrypted only when needed in-memory - Master key stored in ENCRYPTION_KEY environment variable - Updated schema comment to reflect actual encryption method 2. Admin Authorization on Key Regeneration - Created AdminGuard for system-level admin operations - Requires workspace ownership for admin privileges - Key regeneration restricted to admin users only - Proper authorization checks before sensitive operations 3. Private Key Never Exposed in API Responses - Changed regenerateKeypair return type to PublicInstanceIdentity - Service method strips private key before returning - Added tests to verify private key exclusion - Controller returns only public identity ADDITIONAL SECURITY IMPROVEMENTS: 4. Audit Logging for Key Regeneration - Created FederationAuditService - Logs all keypair regeneration events - Includes userId, instanceId, and timestamp - Marked as security events for compliance 5. Input Validation for INSTANCE_URL - Validates URL format (must be HTTP/HTTPS) - Throws error on invalid URLs - Prevents malformed configuration 6. Added .env.example - Documents all required environment variables - Includes INSTANCE_NAME, INSTANCE_URL - Includes ENCRYPTION_KEY with generation instructions - Clear security warnings for production use TESTING: - Added 11 comprehensive crypto service tests - Updated 8 federation service tests for encryption - Updated 5 controller tests for security verification - Total: 24 tests passing (100% success rate) - Verified private key never exposed in responses - Verified encryption/decryption round-trip - Verified admin authorization requirements FILES CREATED: - apps/api/src/federation/crypto.service.ts (encryption) - apps/api/src/federation/crypto.service.spec.ts (tests) - apps/api/src/federation/audit.service.ts (audit logging) - apps/api/src/auth/guards/admin.guard.ts (authorization) - apps/api/.env.example (configuration template) FILES MODIFIED: - apps/api/prisma/schema.prisma (updated comment) - apps/api/src/federation/federation.service.ts (encryption integration) - apps/api/src/federation/federation.controller.ts (admin guard, audit) - apps/api/src/federation/federation.module.ts (new providers) - All test files updated for new security requirements CODE QUALITY: - All tests passing (24/24) - TypeScript compilation: PASS - ESLint: PASS - Test coverage maintained at 100% Fixes #84 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
