# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Project Overview
This is an API Key Management Service (KMS) built with Go backend and React TypeScript frontend. The system manages API keys, user authentication, permissions, and provides both static tokens and user JWT tokens with hierarchical permission scopes.
**Key Technologies:**
- **Backend**: Go 1.23+ with Gin/Gorilla Mux, PostgreSQL, JWT tokens
- **Frontend**: React 19+ with TypeScript, Ant Design 5.27+
- **Infrastructure**: Podman/Docker Compose, Nginx, Redis (optional)
- **Security**: HMAC token signing, RBAC permissions, rate limiting
## Architecture
The project follows clean architecture principles with clear separation:
```
cmd/server/ - Application entry point
internal/ - Go backend core logic
├── domain/ - Domain models and business logic
├── repository/ - Data access interfaces and PostgreSQL implementations
├── services/ - Business logic layer
├── handlers/ - HTTP request handlers (Gin-based)
├── middleware/ - Authentication, logging, security, CSRF middleware
├── config/ - Configuration management with validation
├── auth/ - JWT, OAuth2, SAML, header-based auth providers
├── cache/ - Redis caching layer (optional)
├── metrics/ - Prometheus metrics collection
└── database/ - Database connection and migrations
kms-frontend/ - React TypeScript frontend with Ant Design
migrations/ - PostgreSQL database migration files
test/ - Integration and E2E tests (both Go and bash)
docs/ - Comprehensive technical documentation
nginx/ - Nginx configuration for reverse proxy
```
## Development Commands
### Go Backend
```bash
# Run the server locally (requires environment variables)
INTERNAL_HMAC_KEY=test-hmac-key JWT_SECRET=test-jwt-secret AUTH_SIGNING_KEY=test-signing-key go run cmd/server/main.go
# Build the binary
go build -o api-key-service ./cmd/server
# Run tests (uses kms_test database)
go test -v ./test/...
# Run tests with coverage
go test -v -coverprofile=coverage.out ./test/...
go tool cover -html=coverage.out -o coverage.html
# Run specific test suites
go test -v ./test/ -run TestHealthEndpoints
go test -v ./test/ -run TestApplicationCRUD
go test -v ./test/ -run TestStaticTokenWorkflow
go test -v ./test/ -run TestConcurrentRequests
```
### React Frontend
```bash
# Navigate to frontend directory
cd kms-frontend
# Install dependencies (Node 24+, npm 11+)
npm install
# Start development server
npm start
# Build for production
npm run build
# Run tests
npm test
```
### Podman Compose & Development Environment
**CRITICAL**: This project uses `podman-compose`, not `docker-compose`.
```bash
# Start all services (PostgreSQL, API, Nginx, Frontend)
podman-compose up -d
# Check service health
curl http://localhost:8081/health
# View logs
podman-compose logs -f
# View specific service logs
podman-compose logs -f api-service
podman-compose logs -f postgres
# Stop services
podman-compose down
# Rebuild services after code changes
podman-compose up -d --build
```
## Database Operations
**CRITICAL**: All database operations use `podman exec` commands. Never use direct `psql` commands.
### Database Access
```bash
# Access database shell (container name: kms-postgres)
podman exec -it kms-postgres psql -U postgres -d kms
# Run SQL commands via exec
podman exec -it kms-postgres psql -U postgres -c "SELECT * FROM applications LIMIT 5;"
# Check specific tables
podman exec -it kms-postgres psql -U postgres -d kms -c "\dt"
podman exec -it kms-postgres psql -U postgres -d kms -c "SELECT token_id, app_id, user_id FROM static_tokens LIMIT 5;"
# Apply migrations manually if needed
podman exec -it kms-postgres psql -U postgres -d kms -f /docker-entrypoint-initdb.d/001_initial_schema.up.sql
```
### Database Testing
```bash
# Create test database (if needed)
podman exec -it kms-postgres psql -U postgres -c "CREATE DATABASE kms_test;"
# Reset test database
podman exec -it kms-postgres psql -U postgres -c "DROP DATABASE IF EXISTS kms_test; CREATE DATABASE kms_test;"
# Check test data
podman exec -it kms-postgres psql -U postgres -d kms -c "SELECT * FROM applications WHERE name LIKE 'test-%';"
```
## Testing
The project uses podman-compose for all testing environments and database operations.
### End-to-End Testing
```bash
# Start test environment with podman-compose, guaranteeing that it updates with --build
podman-compose up -d --build
# Wait for services to be ready
sleep 10
# Run comprehensive E2E tests with curl
./test/e2e_test.sh
# Test against specific server and user
BASE_URL=http://localhost:8080 USER_EMAIL=admin@example.com ./test/e2e_test.sh
# Clean up test environment
podman-compose down
```
### Go Integration Tests
```bash
# Run Go integration tests (uses kms_test database)
go test -v ./test/...
# With podman-compose environment
podman-compose up -d
sleep 10
go test -v ./test/...
podman-compose down
```

## API Structure
### Core Endpoints
- **Health**: `/health`, `/ready`
- **Authentication**: `/api/login`, `/api/verify`, `/api/renew`
- **Applications**: `/api/applications` (CRUD operations)
- **Tokens**: `/api/applications/{id}/tokens` (Static token management)
- **Audit**: `/api/audit/events`, `/api/audit/events/:id`, `/api/audit/stats` (Audit log management)
- **Metrics**: `:9090/metrics` (Prometheus format, if enabled)
### Permission System
Hierarchical permission scopes (parent permissions include child permissions):
- `internal.*` - System operations (highest level)
- `app.*` - Application management
- `token.*` - Token operations
- `repo.*` - Repository access (example domain)
- `permission.*` - Permission management
Example: `repo` permission includes `repo.read` and `repo.write`.
## Database Schema
### Key Tables
- `applications` - Application definitions with HMAC keys
- `static_tokens` - Static API tokens with prefixes
- `available_permissions` - Permission catalog
- `granted_permissions` - Token-permission relationships
- `user_sessions` - User session tracking with JWT
- `audit_events` - Comprehensive audit logging with fields:
- `id`, `type`, `severity`, `status`, `timestamp`
- `actor_id`, `actor_type`, `actor_ip`, `user_agent`
- `resource_id`, `resource_type`, `action`, `description`
- `details` (JSON), `request_id`, `session_id`
### Migration System
- Auto-runs on startup
- Located in `/migrations/`
- Uses `golang-migrate/migrate/v4`
- Supports both up and down migrations
## Code Patterns & Architecture
### Backend Patterns
- **Repository Pattern**: Data access via interfaces (`internal/repository/interfaces.go`)
- **Dependency Injection**: Services receive dependencies via constructors
- **Middleware Chain**: Security, auth, logging, rate limiting
- **Structured Errors**: Custom error types with proper HTTP status codes
- **Structured Logging**: Zap logger with JSON output
- **Configuration Provider**: Interface-based config with validation
- **Multiple Auth Providers**: Header, OAuth2, SAML support
### Frontend Patterns
- **React 19** with TypeScript
- **Ant Design 5.27+** component library
- **Context API** for authentication state (`AuthContext.tsx`)
- **Axios** for API communication with interceptors
- **React Router 7+** for navigation
- **Component Structure**: Organized by feature (Applications, Tokens, Users, Audit)
- **Audit Integration**: Real-time audit log viewing with filtering, statistics, and timeline views
### Security Patterns
- **HMAC Token Signing**: All tokens cryptographically signed
- **JWT with Rotation**: User tokens with refresh capability
- **Rate Limiting**: Per-endpoint and per-user limits
- **CSRF Protection**: Token-based CSRF protection
- **Audit Logging**: All operations logged with user attribution
- **Input Validation**: Comprehensive validation at all layers
### Audit System Architecture
- **Handler**: `internal/handlers/audit.go` - HTTP endpoints for audit data
- **Logger**: `internal/audit/audit.go` - Core audit logging functionality
- **Repository**: `internal/repository/postgres/audit_repository.go` - Data persistence
- **Frontend**: `kms-frontend/src/components/Audit.tsx` - Real-time audit viewing
- **API Service**: `kms-frontend/src/services/apiService.ts` - Frontend-backend integration
- **Event Types**: Hierarchical (e.g., `auth.login`, `app.created`, `token.validated`)
- **Filtering**: Support for date ranges, event types, statuses, users, resource types
- **Statistics**: Aggregated metrics by type, severity, status, and time
## Development Notes
### Critical Information
- **Go Version**: Requires Go 1.23+ (currently using 1.24.4)
- **Node Version**: Requires Node 24+ and npm 11+
- **Database**: Auto-migrations run on startup
- **Container Names**: Use `kms-postgres`, `kms-api-service`, `kms-frontend`, `kms-nginx`
- **Default Ports**: API:8080, Nginx:8081, Frontend:3000, DB:5432, Metrics:9090
- **Test Database**: `kms_test` (separate from `kms`)
### Important Files
- `internal/config/config.go` - Complete configuration management
- `docker-compose.yml` - Service definitions and environment variables
- `test/e2e_test.sh` - Comprehensive curl-based E2E tests
- `test/README.md` - Detailed testing guide
- `docs/` - Technical documentation (Architecture, Security, API docs)
### Development Workflow
1. Always use `podman-compose` (not `docker-compose`)
2. Database operations via `podman exec` only
3. Required environment variables for local dev (HMAC, JWT, AUTH keys)
4. Run tests after changes: `go test -v ./test/...`
5. Use E2E tests to verify end-to-end functionality
6. Frontend dev server connects to containerized backend
### Build & Deployment Notes
- **Cache Issues**: When code changes don't appear, use `podman-compose build --no-cache`
- **Route Registration**: New API routes require full rebuild to appear in Gin debug logs
- **Error Handlers**: Use `HandleInternalError`, `HandleValidationError`, `HandleAuthenticationError`
- **API Integration**: Frontend components should use real API calls, not mock data
- **Field Mapping**: Ensure frontend matches backend field names (e.g., `actor_id` vs `user_id`)
### Security Considerations
- Never commit secrets to repository
- All tokens use HMAC signing with secure keys
- Rate limiting prevents abuse
- Comprehensive audit logging for compliance
- Input validation at all layers
- CORS and security headers properly configured

## Permission Scopes
The following permission scopes are available:
### System Permissions
- `internal` - Full access to internal system operations (system only)
- `internal.read` - Read access to internal system data (system only)
- `internal.write` - Write access to internal system data (system only)
- `internal.admin` - Administrative access to internal system (system only)
### Application Management
- `app` - Access to application management
- `app.read` - Read application information
- `app.write` - Create and update applications
- `app.delete` - Delete applications
### Token Management
- `token` - Access to token management
- `token.read` - Read token information
- `token.create` - Create new tokens
- `token.revoke` - Revoke existing tokens
### Permission Management
- `permission` - Access to permission management
- `permission.read` - Read permission information
- `permission.write` - Create and update permissions
- `permission.grant` - Grant permissions to tokens

### Repository Access (Example)
- `repo` - Access to repository operations
- `repo.read` - Read repository data
- `repo.write` - Write to repositories
- `repo.admin` - Administrative access to repositories
## Rate Limiting
The API implements rate limiting with the following limits:
- **General API endpoints**: 100 requests per minute with burst of 20
- **Authentication endpoints** (`/login`, `/verify`, `/renew`): 10 requests per minute with burst of 5
Rate limit headers are included in responses:
- `X-RateLimit-Limit`: Request limit per window
- `X-RateLimit-Remaining`: Remaining requests in current window
- `X-RateLimit-Reset`: Unix timestamp when the window resets
When rate limited:
```json
{
"error": "Rate limit exceeded",
"message": "Too many requests. Please try again later."
}
```
## Testing Endpoints
For testing purposes, different user scenarios are available through different ports:
- **Port 80**: Regular user (`test@example.com`)
- **Port 8081**: Admin user (`admin@example.com`) with higher rate limits
- **Port 8082**: Limited user (`limited@example.com`) with lower rate limits
## Example Workflows
### Creating an Application and Static Token
1. **Create Application:**
```bash
curl -X POST http://localhost/api/applications \
-H "Content-Type: application/json" \
-H "X-User-Email: admin@example.com" \
-d '{
"app_id": "com.mycompany.api",
"app_link": "https://api.mycompany.com",
"type": ["static", "user"],
"callback_url": "https://api.mycompany.com/callback",
"token_renewal_duration": "168h",
"max_token_duration": "720h",
"owner": {
"type": "team",
"name": "API Team",
"owner": "api-team@mycompany.com"
}
}'
```
2. **Create Static Token:**
```bash
curl -X POST http://localhost/api/applications/com.mycompany.api/tokens \
-H "Content-Type: application/json" \
-H "X-User-Email: admin@example.com" \
-d '{
"owner": {
"type": "individual",
"name": "Service Account",
"owner": "service@mycompany.com"
},
"permissions": ["repo.read", "repo.write"]
}'
```
3. **Verify Token:**
```bash
curl -X POST http://localhost/api/verify \
-H "Content-Type: application/json" \
-d '{
"app_id": "com.mycompany.api",
"type": "static",
"token": "static-token-abc123xyz789",
"permissions": ["repo.read"]
}'
```
### User Authentication Flow
1. **Initiate Login:**
```bash
curl -X POST http://localhost/api/login \
-H "Content-Type: application/json" \
-H "X-User-Email: user@example.com" \
-d '{
"app_id": "com.mycompany.api",
"permissions": ["repo.read"],
"redirect_uri": "https://myapp.com/callback"
}'
```
2. **Verify User Token:**
```bash
curl -X POST http://localhost/api/verify \
-H "Content-Type: application/json" \
-d '{
"app_id": "com.mycompany.api",
"type": "user",
"user_id": "user@example.com",
"token": "user-token-from-login",
"permissions": ["repo.read"]
}'
```
3. **Renew Token Before Expiry:**
```bash
curl -X POST http://localhost/api/renew \
-H "Content-Type: application/json" \
-d '{
"app_id": "com.mycompany.api",
"user_id": "user@example.com",
"token": "current-user-token"
}'
```
## Security Considerations
- All tokens should be transmitted over HTTPS in production
- Static tokens are returned only once during creation - store them securely
- User tokens have both renewal and maximum validity periods
- HMAC keys are used for token signing and should be rotated regularly
- Rate limiting helps prevent abuse
- Permission scopes follow hierarchical structure
- All operations are logged with user attribution
## Development and Testing
The service includes comprehensive health checks, detailed logging, and metrics collection. When running with `LOG_LEVEL=debug`, additional debugging information is available in the logs.
For local development, the service can be started with:
```bash
docker-compose up -d
```
This starts PostgreSQL, the API service, and Nginx proxy with test user headers configured.

## System Overview
The API Key Management Service (KMS) is a secure, scalable platform for managing API authentication tokens across applications. Built with Go backend and React TypeScript frontend, it provides centralized token lifecycle management with enterprise-grade security features.
### Key Capabilities
- **Multi-Provider Authentication**: Header, JWT, OAuth2, SAML support
- **Dual Token System**: Static HMAC tokens and renewable JWT user tokens
- **Hierarchical Permissions**: Role-based access control with inheritance
- **Enterprise Security**: Rate limiting, brute force protection, audit logging
- **High Availability**: Containerized deployment with load balancing
### Core Features
- **Token Lifecycle Management**: Create, verify, renew, and revoke tokens
- **Application Management**: Multi-tenant application configuration
- **User Session Tracking**: Comprehensive session management
- **Audit Logging**: Complete audit trail of all operations
- **Health Monitoring**: Built-in health checks and metrics
---
## Architecture Principles
### Clean Architecture
The system follows clean architecture principles with clear separation of concerns:
```
┌─────────────────┐
│ Handlers │ ← HTTP request handling
├─────────────────┤
│ Services │ ← Business logic
├─────────────────┤
│ Repositories │ ← Data access
├─────────────────┤
│ Database │ ← Data persistence
└─────────────────┘
```
### Design Principles
- **Dependency Injection**: All services receive dependencies through constructors
- **Interface Segregation**: Repository interfaces enable testing and flexibility
- **Single Responsibility**: Each component has one clear purpose
- **Fail-Safe Defaults**: Security-first configuration with safe fallbacks
- **Immutable Operations**: Database transactions and audit logging
- **Defense in Depth**: Multiple security layers throughout the stack

## 📝 Implementation Notes for Future Development
### Code Organization Principles
1. **Maintain Clean Architecture**: Keep clear separation between domain, service, and infrastructure layers
2. **Interface-First Design**: Always define interfaces before implementations for better testability
3. **Error Handling**: Use the established error framework (`internal/errors`) for consistent error handling
4. **Logging**: Use structured logging with zap throughout the application
5. **Configuration**: Add new config options to `internal/config/config.go` with proper validation
### Security Guidelines
1. **Input Validation**: Always validate inputs using the validation middleware (`internal/middleware/validation.go`)
2. **Token Security**: Use the crypto utilities (`internal/crypto/token.go`) for all token operations
3. **Permission Checks**: Always validate permissions using the repository layer before operations
4. **Audit Logging**: Log all security-relevant operations with user context
5. **Secrets**: Never hardcode secrets; use environment variables or secret management systems
### Database Guidelines
1. **Migrations**: Always create both up and down migrations for schema changes
2. **Transactions**: Use database transactions for multi-step operations
3. **Indexing**: Add appropriate indexes for query performance
4. **Connection Management**: Use the existing connection pool configuration
5. **Error Handling**: Wrap database errors with the application error framework
### Testing Guidelines
1. **Test Structure**: Follow the existing test structure in `test/` directory
2. **Mock Dependencies**: Use interfaces for easy mocking in tests
3. **Test Data**: Use the test helpers for consistent test data creation
4. **Integration Tests**: Test against real database instances when possible
5. **Coverage**: Aim for >80% test coverage for critical paths
### Performance Guidelines
1. **Metrics**: Use the metrics system (`internal/metrics`) to track performance
2. **Caching**: Implement caching at the service layer, not repository layer
3. **Database Queries**: Optimize queries and use appropriate indexes
4. **Memory Management**: Be mindful of memory allocations in hot paths
5. **Concurrency**: Use proper synchronization for shared resources
### Deployment Guidelines
1. **Environment Variables**: Use environment-based configuration for all deployments
2. **Health Checks**: Ensure health endpoints are properly configured
3. **Graceful Shutdown**: Implement proper shutdown procedures for all services
4. **Resource Limits**: Set appropriate CPU and memory limits
5. **Monitoring**: Ensure metrics and logging are properly configured
### Code Quality Standards
1. **Go Standards**: Follow standard Go conventions and best practices
2. **Documentation**: Document all public APIs and complex business logic
3. **Error Messages**: Provide clear, actionable error messages
4. **Code Reviews**: Require code reviews for all changes
5. **Static Analysis**: Use tools like golangci-lint for code quality
### Security Best Practices
1. **Principle of Least Privilege**: Grant minimum necessary permissions
2. **Defense in Depth**: Implement multiple layers of security
3. **Regular Updates**: Keep dependencies updated for security patches
4. **Secure Defaults**: Use secure configurations by default
5. **Security Testing**: Include security testing in the development process
### Operational Considerations
1. **Monitoring**: Implement comprehensive monitoring and alerting
2. **Backup Strategy**: Ensure regular backups and test restore procedures
3. **Disaster Recovery**: Have documented disaster recovery procedures
4. **Capacity Planning**: Monitor resource usage and plan for growth

```go
// HMAC signature validation with constant-time comparison
func (hv *HeaderValidator) validateSignature(userEmail, timestamp, signature string) bool {
mac := hmac.New(sha256.New, []byte(signingKey))
mac.Write([]byte(signingString))
expectedSignature := hex.EncodeToString(mac.Sum(nil))
return hmac.Equal([]byte(signature), []byte(expectedSignature))
}
```

## Token Security Models
### Static Token Security (HMAC-based)
```mermaid
stateDiagram-v2
[*] --> TokenRequest: Client requests token
state TokenRequest {
[*] --> ValidateApp: Validate app_id
ValidateApp --> ValidatePerms: Check permissions
ValidatePerms --> GenerateToken: Create token
GenerateToken --> [*]
}
TokenRequest --> StaticToken: type=static
state StaticToken {
[*] --> GenerateHMAC: Generate HMAC key
GenerateHMAC --> HashKey: BCrypt hash (cost 14)
HashKey --> StoreDB: Store in static_tokens table
StoreDB --> GrantPerms: Assign permissions
GrantPerms --> Active: Token ready
Active --> Verify: Incoming request
Verify --> ValidateHMAC: Check HMAC signature
ValidateHMAC --> CheckTimestamp: Replay protection
CheckTimestamp --> CheckPerms: Validate permissions
CheckPerms --> Authorized: Permission check
CheckPerms --> Denied: Permission denied
Active --> Revoke: Admin action
Revoke --> Revoked: Update granted_permissions.revoked=true
}
Authorized --> TokenResponse: Success response
Denied --> ErrorResponse: Error response
Revoked --> [*]: Token lifecycle end
note right of StaticToken
Static tokens use HMAC signatures
- Timestamp-based replay protection
- BCrypt hashed storage
- Permission-based access control
- No expiration (until revoked)
end note
```
#### **Token Format**
```
Format: {PREFIX}_{BASE64_DATA}
Example: ABC_xyz123base64encodeddata...
Validation: HMAC-SHA256(request_data, hmac_key)
Storage: BCrypt hash (cost 14)
Lifetime: No expiration (until revoked)
```
#### **Security Implementation**
```go
// File: internal/crypto/token.go:95
func (tg *TokenGenerator) HashToken(token string) (string, error) {
hash, err := bcrypt.GenerateFromPassword([]byte(token), tg.bcryptCost)
if err != nil {
return "", fmt.Errorf("failed to hash token with bcrypt cost %d: %w", tg.bcryptCost, err)
}
return string(hash), nil
}
```
### User Token Security (JWT-based)
```mermaid
stateDiagram-v2
[*] --> UserTokenRequest: User requests token
state UserTokenRequest {
[*] --> AuthUser: Authenticate user
AuthUser --> GenerateJWT: Create JWT with claims
GenerateJWT --> SetExpiry: Set expires_at, max_valid_at
SetExpiry --> StoreSession: Store user session
StoreSession --> Active: JWT issued
}
UserTokenRequest --> UserToken: type=user
state UserToken {
Active --> Verify: Incoming request
Verify --> ValidateJWT: Check JWT signature
ValidateJWT --> CheckExpiry: Verify expiration
CheckExpiry --> CheckRevoked: Check revocation list
CheckRevoked --> Authorized: Valid token
CheckRevoked --> Denied: Token invalid
CheckExpiry --> Expired: Token expired
Active --> Renew: Renewal request
Renew --> CheckRenewal: Within renewal window?
CheckRenewal --> GenerateNew: Issue new JWT
CheckRenewal --> Denied: Renewal denied
GenerateNew --> Active: New token active
Active --> Logout: User logout
Logout --> Revoked: Add to revocation list
Expired --> Renew: Attempt renewal
}
Authorized --> TokenResponse: Success response
Denied --> ErrorResponse: Error response
Revoked --> [*]: Token lifecycle end
note right of UserToken
User tokens are JWT-based
- Configurable expiration
- Renewable within limits
- Session tracking
- Hierarchical permissions
end note
```
#### **Token Format**
```
Format: {CUSTOM_PREFIX}UT-{JWT_TOKEN}
Example: ABC123UT-eyJhbGciOiJSUzI1NiIs...
Validation: RSA signature + claims validation
Storage: Revocation list in Redis
Lifetime: Configurable with renewal window
```
#### **Security Features**
- **RSA-256 Signatures**: Strong cryptographic validation
- **Token Revocation**: Redis blacklist with TTL
- **Renewal Controls**: Limited renewal window
- **Session Tracking**: Database session management

## Authorization Framework
### Role-Based Access Control (RBAC)
The KMS implements a hierarchical permission system with role-based access control:
#### **Permission Hierarchy**
```
admin
├── app.admin
│ ├── app.read
│ ├── app.write
│ │ ├── app.create
│ │ ├── app.update
│ │ └── app.delete
├── token.admin
│ ├── token.read
│ │ └── token.verify
│ ├── token.write
│ │ ├── token.create
│ │ └── token.revoke
├── permission.admin
│ ├── permission.read
│ ├── permission.write
│ │ ├── permission.grant
│ │ └── permission.revoke
└── user.admin
├── user.read
└── user.write
```
#### **Role Definitions**
```go
// File: internal/auth/permissions.go:151
func (h *PermissionHierarchy) initializeDefaultRoles() {
defaultRoles := []*Role{
{
Name: "super_admin",
Description: "Super administrator with full access",
Permissions: []string{"admin"},
Metadata: map[string]string{"level": "system"},
},
{
Name: "app_admin",
Description: "Application administrator",
Permissions: []string{"app.admin", "token.admin", "user.read"},
Metadata: map[string]string{"level": "application"},
},
// Additional roles...
}
}
```
#### **Permission Evaluation**
```go
// File: internal/auth/permissions.go:201
func (pm *PermissionManager) HasPermission(ctx context.Context, userID, appID, permission string) (*PermissionEvaluation, error) {
// Cache lookup first
cacheKey := cache.CacheKey(cache.KeyPrefixPermission, fmt.Sprintf("%s:%s:%s", userID, appID, permission))
// Evaluate permission with hierarchy
evaluation := pm.evaluatePermission(ctx, userID, appID, permission)
// Cache result for 5 minutes
pm.cacheManager.SetJSON(ctx, cacheKey, evaluation, 5*time.Minute)
return evaluation, nil
}
```
### Authorization Controls
#### **Resource Ownership**
```go
// File: internal/authorization/rbac.go:100
func (a *AuthorizationService) AuthorizeApplicationOwnership(userID string, app *domain.Application) error {
// System admins can access any application
if a.isSystemAdmin(userID) {
return nil
}
// Check if user is the owner
if a.isOwner(userID, &app.Owner) {
return nil
}
return errors.NewForbiddenError("You do not have permission to access this application")
}
```
#### **Token Scoping**
```go
// File: internal/services/token_service.go:400
func (s *tokenService) verifyStaticToken(ctx context.Context, req *domain.VerifyRequest, app *domain.Application) (*domain.VerifyResponse, error) {
// Get granted permissions for this token
permissions, err := s.grantRepo.GetGrantedPermissionScopes(ctx, domain.TokenTypeStatic, matchedToken.ID)
// Check specific permissions if requested
if len(req.Permissions) > 0 {
permissionResults, err := s.grantRepo.HasAnyPermission(ctx, domain.TokenTypeStatic, matchedToken.ID, req.Permissions)
// Validate all requested permissions are granted
}
}
```
---
## Data Protection
### Encryption at Rest
#### **Database Encryption**
```sql
-- Sensitive data encryption in PostgreSQL
CREATE TABLE applications (
app_id VARCHAR(100) PRIMARY KEY,
hmac_key TEXT, -- Encrypted with application-level encryption
created_at TIMESTAMP DEFAULT NOW()
);
CREATE TABLE static_tokens (
id UUID PRIMARY KEY,
key_hash TEXT NOT NULL, -- BCrypt hashed with cost 14
created_at TIMESTAMP DEFAULT NOW()
);
```
#### **BCrypt Hashing**
```go
// File: internal/crypto/token.go:22
const BcryptCost = 14 // 2025 security standards (minimum 14)
func (tg *TokenGenerator) HashToken(token string) (string, error) {
hash, err := bcrypt.GenerateFromPassword([]byte(token), tg.bcryptCost)
if err != nil {
return "", fmt.Errorf("failed to hash token with bcrypt cost %d: %w", tg.bcryptCost, err)
}
return string(hash), nil
}
```
### Encryption in Transit
#### **TLS Configuration**
```go
// TLS 1.3 configuration for all communications
tlsConfig := &tls.Config{
MinVersion: tls.VersionTLS13,
CipherSuites: []uint16{
tls.TLS_AES_256_GCM_SHA384,
tls.TLS_CHACHA20_POLY1305_SHA256,
tls.TLS_AES_128_GCM_SHA256,
},
}
```
#### **Certificate Pinning**
```go
// OAuth2/SAML provider certificate pinning
func (o *OAuth2Provider) validateCertificate(cert *x509.Certificate) error {
expectedFingerprints := o.config.GetStringSlice("OAUTH2_CERT_FINGERPRINTS")
fingerprint := sha256.Sum256(cert.Raw)
fingerprintHex := hex.EncodeToString(fingerprint[:])
for _, expected := range expectedFingerprints {
if fingerprintHex == expected {
return nil
}
}
return fmt.Errorf("certificate fingerprint mismatch")
}
```
---
## Security Middleware Chain
### Middleware Processing Order
1. **Request Logger**: Structured logging with security context
2. **Security Headers**: XSS, clickjacking, MIME-type protection
3. **CORS Handler**: Cross-origin request validation
4. **CSRF Protection**: Double-submit token validation
5. **Rate Limiter**: DDoS and abuse protection
6. **Authentication**: Multi-provider authentication
7. **Authorization**: Permission validation
8. **Input Validation**: Request sanitization and validation
### Rate Limiting Implementation
```go
// File: internal/middleware/security.go:48
func (s *SecurityMiddleware) RateLimitMiddleware(next http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
clientIP := s.getClientIP(r)
limiter := s.getRateLimiter(clientIP)
if !limiter.Allow() {
s.logger.Warn("Rate limit exceeded",
zap.String("client_ip", clientIP),
zap.String("path", r.URL.Path))
s.trackRateLimitViolation(clientIP)
http.Error(w, `{"error":"rate_limit_exceeded"}`, http.StatusTooManyRequests)
return
}
next.ServeHTTP(w, r)
})
}
```
### Brute Force Protection
```go
// File: internal/middleware/security.go:365
func (s *SecurityMiddleware) checkAndBlockIP(clientIP string) {
var count int
err := s.cacheManager.GetJSON(ctx, key, &count)
maxFailures := s.config.GetInt("MAX_AUTH_FAILURES")
if maxFailures <= 0 {
maxFailures = 5 // Default
}
if count >= maxFailures {
// Block the IP for 1 hour
blockInfo := map[string]interface{}{
"blocked_at": time.Now().Unix(),
"failure_count": count,
"reason": "excessive_auth_failures",
}
s.cacheManager.SetJSON(ctx, blockKey, blockInfo, blockDuration)
}
}
```

## Documentation Consistency Analysis
### Current State Assessment
The existing documentation is comprehensive but has some minor inconsistencies with the actual codebase:
#### ✅ Accurate Documentation Areas:
- **API endpoints** match the implementation in handlers
- **Database schema** aligns with migrations (especially the new audit_events table)
- **Authentication flows** are correctly documented
- **Docker compose setup** matches actual configuration
- **Security architecture** accurately reflects implementation
- **Permission system** documentation is consistent with code
#### ⚠️ Minor Inconsistencies Found:
1. **Port references**: Some docs mention port 80 but actual nginx runs on 8081
2. **Container names**: Documentation uses generic names, actual compose uses specific names like `kms-postgres`
3. **Rate limiting values**: Docs show different values than actual middleware implementation
4. **Frontend build process**: React version mentioned as 18, but package.json shows 19+
#### ✨ Recently Added Features (Not in Original Docs):
- **Audit system** with comprehensive event logging
- **Multi-tenancy support** in database schema
- **Advanced caching layer** with Redis integration
- **SAML authentication** implementation
- **Advanced security middleware** with brute force protection
---
## Audit System Implementation

```
#### Database Schema
```sql
-- File: migrations/004_add_audit_events.up.sql
CREATE TABLE audit_events (
id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
type VARCHAR(50) NOT NULL,
severity VARCHAR(20) NOT NULL CHECK (severity IN ('info', 'warning', 'error', 'critical')),
status VARCHAR(20) NOT NULL CHECK (status IN ('success', 'failure', 'pending')),
timestamp TIMESTAMP WITH TIME ZONE NOT NULL DEFAULT NOW(),
-- Actor information
actor_id VARCHAR(255),
actor_type VARCHAR(50) CHECK (actor_type IN ('user', 'system', 'service')),
actor_ip INET,
user_agent TEXT,
-- Multi-tenancy
tenant_id UUID,
-- Resource tracking
resource_id VARCHAR(255),
resource_type VARCHAR(100),
action VARCHAR(100) NOT NULL,
description TEXT NOT NULL,
details JSONB DEFAULT '{}',
-- Request context
request_id VARCHAR(100),
session_id VARCHAR(255),
-- Metadata
tags TEXT[],
metadata JSONB DEFAULT '{}'
);
```
#### Frontend Integration
```typescript
// File: kms-frontend/src/components/Audit.tsx
interface AuditEvent {
id: string;
type: string;
severity: 'info' | 'warning' | 'error' | 'critical';
status: 'success' | 'failure' | 'pending';
timestamp: string;
actor_id: string;
actor_type: string;
resource_type: string;
action: string;
description: string;
}
const Audit: React.FC = () => {
// Real-time audit log viewing with filtering
// Timeline view for event sequences
// Statistics dashboard for audit metrics
};
```
### Implementation Guidelines
#### Logging Best Practices
1. **Log all security-relevant events**
2. **Include sufficient context** for forensic analysis
3. **Use structured logging** with consistent fields
4. **Implement log retention policies**
5. **Ensure tamper-evident logging**
#### Performance Considerations
1. **Asynchronous logging** to avoid blocking operations
2. **Batch inserts** for high-volume events
3. **Proper indexing** on commonly queried fields
4. **Archival strategy** for historical data
---
## Multi-Tenancy Support
### Architecture
The KMS implements a multi-tenant architecture where each tenant has isolated data and permissions while sharing the same application instance.
### Database Design
#### Tenant Model
```go
// File: internal/domain/tenant.go
type Tenant struct {
ID uuid.UUID `json:"id" db:"id"`
Name string `json:"name" db:"name"`
Slug string `json:"slug" db:"slug"`
Status TenantStatus `json:"status" db:"status"`
Settings TenantSettings `json:"settings" db:"settings"`
Metadata map[string]interface{} `json:"metadata" db:"metadata"`
CreatedAt time.Time `json:"created_at" db:"created_at"`
UpdatedAt time.Time `json:"updated_at" db:"updated_at"`
}
type TenantStatus string
const (
TenantStatusActive TenantStatus = "active"
TenantStatusSuspended TenantStatus = "suspended"
TenantStatusPending TenantStatus = "pending"
)
```
#### Data Isolation Strategy
```sql
-- All tenant-specific tables include tenant_id
ALTER TABLE applications ADD COLUMN tenant_id UUID REFERENCES tenants(id);
ALTER TABLE static_tokens ADD COLUMN tenant_id UUID REFERENCES tenants(id);
ALTER TABLE user_sessions ADD COLUMN tenant_id UUID REFERENCES tenants(id);
ALTER TABLE audit_events ADD COLUMN tenant_id UUID;
-- Row-level security policies
ALTER TABLE applications ENABLE ROW LEVEL SECURITY;
CREATE POLICY tenant_isolation ON applications
FOR ALL TO kms_user
USING (tenant_id = current_setting('app.current_tenant')::UUID);
```
### Implementation Pattern
#### Tenant Context Middleware
```go
// File: internal/middleware/tenant.go
func TenantMiddleware() gin.HandlerFunc {
return func(c *gin.Context) {
tenantID := extractTenantID(c)
if tenantID == "" {
c.AbortWithStatusJSON(400, gin.H{"error": "tenant_required"})
return
}
// Set tenant context
c.Set("tenant_id", tenantID)
// Set database session variable
db := c.MustGet("db").(*sql.DB)
_, err := db.Exec("SELECT set_config('app.current_tenant', $1, true)", tenantID)
if err != nil {
c.AbortWithStatusJSON(500, gin.H{"error": "tenant_setup_failed"})
return
}
c.Next()
}
}
```
### Usage Guidelines
1. **Always include tenant_id** in database queries
2. **Validate tenant access** in middleware
3. **Implement tenant-aware caching**
4. **Audit cross-tenant operations**
5. **Test tenant isolation thoroughly**
---
## Cache Implementation Details
### Architecture
The KMS implements a layered caching system with multiple providers and configurable TTL policies.
### Cache Interface
```go
// File: internal/cache/cache.go
type CacheManager interface {
Get(ctx context.Context, key string) ([]byte, error)
Set(ctx context.Context, key string, value []byte, ttl time.Duration) error
GetJSON(ctx context.Context, key string, dest interface{}) error
SetJSON(ctx context.Context, key string, value interface{}, ttl time.Duration) error
Delete(ctx context.Context, key string) error
Clear(ctx context.Context) error
Exists(ctx context.Context, key string) (bool, error)
}
```
### Redis Implementation
```go
// File: internal/cache/redis.go
type RedisCacheManager struct {
client redis.Client
keyPrefix string
serializer JSONSerializer
logger *zap.Logger
}
func (r *RedisCacheManager) GetJSON(ctx context.Context, key string, dest interface{}) error {
prefixedKey := r.keyPrefix + key
data, err := r.client.Get(ctx, prefixedKey).Bytes()
if err != nil {
if err == redis.Nil {
return ErrCacheMiss
}
return fmt.Errorf("failed to get key %s: %w", prefixedKey, err)
}
return r.serializer.Deserialize(data, dest)
}
```
### Cache Key Management
```go
type CacheKey string
const (
KeyPrefixAuth = "auth:"
KeyPrefixToken = "token:"
KeyPrefixPermission = "perm:"
KeyPrefixSession = "sess:"
KeyPrefixApp = "app:"
)
func CacheKey(prefix, suffix string) string {
return fmt.Sprintf("%s%s", prefix, suffix)
}
```
### Usage Patterns
#### Authentication Caching
```go
// Cache authentication results for 5 minutes
cacheKey := cache.CacheKey(cache.KeyPrefixAuth, fmt.Sprintf("%s:%s", userID, appID))
err := cacheManager.SetJSON(ctx, cacheKey, authResult, 5*time.Minute)
```
#### Token Revocation List
```go
// Cache revoked tokens until their expiration
revokedKey := cache.CacheKey(cache.KeyPrefixToken, "revoked:"+tokenID)
err := cacheManager.Set(ctx, revokedKey, []byte("1"), tokenExpiry.Sub(time.Now()))
```
### Configuration
```bash
# Cache configuration
CACHE_ENABLED=true
CACHE_PROVIDER=redis # or memory
REDIS_ADDR=localhost:6379
REDIS_PASSWORD=
REDIS_DB=0
CACHE_DEFAULT_TTL=5m
```
---
## Error Handling Framework
### Error Type Hierarchy
```go
// File: internal/errors/errors.go
type ErrorCode string
const (
ErrorCodeValidation ErrorCode = "validation_error"
ErrorCodeAuthentication ErrorCode = "authentication_error"
ErrorCodeAuthorization ErrorCode = "authorization_error"
ErrorCodeNotFound ErrorCode = "not_found"
ErrorCodeConflict ErrorCode = "conflict"
ErrorCodeInternal ErrorCode = "internal_error"
ErrorCodeRateLimit ErrorCode = "rate_limit_exceeded"
ErrorCodeBadRequest ErrorCode = "bad_request"
)
type APIError struct {
Code ErrorCode `json:"code"`
Message string `json:"message"`
Details interface{} `json:"details,omitempty"`
HTTPStatus int `json:"-"`
Cause error `json:"-"`
}
```
### Error Factory Functions
```go
func NewValidationError(message string, details interface{}) *APIError {
return &APIError{
Code: ErrorCodeValidation,
Message: message,
Details: details,
HTTPStatus: http.StatusBadRequest,
}
}
func NewAuthenticationError(message string) *APIError {
return &APIError{
Code: ErrorCodeAuthentication,
Message: message,
HTTPStatus: http.StatusUnauthorized,
}
}
```
### Error Handler Middleware
```go
// File: internal/errors/secure_responses.go
func (e *ErrorHandler) HandleError(c *gin.Context, err error) {
var apiErr *APIError
if errors.As(err, &apiErr) {
// Log error with context
e.logger.Error("API error",
zap.String("error_code", string(apiErr.Code)),
zap.String("message", apiErr.Message),
zap.Int("http_status", apiErr.HTTPStatus),
zap.Error(apiErr.Cause))
c.JSON(apiErr.HTTPStatus, gin.H{
"error": apiErr.Code,
"message": apiErr.Message,
"details": apiErr.Details,
})
return
}
// Handle unexpected errors
e.logger.Error("Unexpected error", zap.Error(err))
c.JSON(http.StatusInternalServerError, gin.H{
"error": ErrorCodeInternal,
"message": "An internal error occurred",
})
}
```
---
## Validation System
### Validator Implementation
```go
// File: internal/validation/validator.go
type Validator struct {
validator *validator.Validate
logger *zap.Logger
}
func NewValidator(logger *zap.Logger) *Validator {
v := validator.New()
// Register custom validators
v.RegisterValidation("app_id", validateAppID)
v.RegisterValidation("token_type", validateTokenType)
v.RegisterValidation("permission_scope", validatePermissionScope)
return &Validator{
validator: v,
logger: logger,
}
}
```
### Custom Validation Rules
```go
func validateAppID(fl validator.FieldLevel) bool {
appID := fl.Field().String()
// App ID format: domain.app (e.g., com.example.app)
pattern := `^[a-z0-9]+(\.[a-z0-9]+)*\.[a-z0-9]+$`
match, _ := regexp.MatchString(pattern, appID)
return match && len(appID) >= 3 && len(appID) <= 100
}
func validatePermissionScope(fl validator.FieldLevel) bool {
scope := fl.Field().String()
// Permission format: domain.action (e.g., app.read)
pattern := `^[a-z_]+(\.[a-z_]+)*$`
match, _ := regexp.MatchString(pattern, scope)
return match && len(scope) >= 1 && len(scope) <= 50
}
```
### Middleware Integration
```go
// File: internal/middleware/validation.go
func (v *ValidationMiddleware) ValidateJSON(schema interface{}) gin.HandlerFunc {
return gin.HandlerFunc(func(c *gin.Context) {
if err := c.ShouldBindJSON(schema); err != nil {
var validationErrors []ValidationError
if errs, ok := err.(validator.ValidationErrors); ok {
for _, e := range errs {
validationErrors = append(validationErrors, ValidationError{
Field: e.Field(),
Message: e.Tag(),
Value: e.Value(),
})
}
}
apiErr := errors.NewValidationError("Request validation failed", validationErrors)
v.errorHandler.HandleError(c, apiErr)
return
}
c.Next()
})
}
```
---
## Metrics and Monitoring
### Prometheus Integration
```go
// File: internal/metrics/metrics.go
type Metrics struct {
// HTTP metrics
httpRequestsTotal *prometheus.CounterVec
httpRequestDuration *prometheus.HistogramVec
httpRequestsInFlight prometheus.Gauge
// Auth metrics
authAttemptsTotal *prometheus.CounterVec
authSuccessTotal *prometheus.CounterVec
authFailuresTotal *prometheus.CounterVec
// Token metrics
tokensIssuedTotal *prometheus.CounterVec
tokenValidationsTotal *prometheus.CounterVec
// Business metrics
applicationsTotal prometheus.Gauge
activeSessionsTotal prometheus.Gauge
}
```
### Metrics Collection
```go

## Database Migration System
### Migration Structure
```
migrations/
├── 001_initial_schema.up.sql
├── 001_initial_schema.down.sql
├── 002_user_sessions.up.sql
├── 002_user_sessions.down.sql
├── 003_add_token_prefix.up.sql
├── 003_add_token_prefix.down.sql
├── 004_add_audit_events.up.sql
└── 004_add_audit_events.down.sql
```
### Migration Runner
```go
// File: internal/database/postgres.go
func RunMigrations(db *sql.DB, migrationPath string) error {
driver, err := postgres.WithInstance(db, &postgres.Config{})
if err != nil {
return fmt.Errorf("failed to create migration driver: %w", err)
}
m, err := migrate.NewWithDatabaseInstance(
fmt.Sprintf("file://%s", migrationPath),
"postgres", driver)
if err != nil {
return fmt.Errorf("failed to create migration instance: %w", err)
}
if err := m.Up(); err != nil && err != migrate.ErrNoChange {
return fmt.Errorf("failed to run migrations: %w", err)
}
return nil
}
```
### Migration Best Practices
1. **Always create both up and down migrations**
2. **Test migrations on copy of production data**
3. **Make migrations idempotent**
4. **Add proper indexes for performance**
5. **Include rollback procedures**
### Example Migration
```sql
-- 005_add_oauth_providers.up.sql
CREATE TABLE IF NOT EXISTS oauth_providers (
id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
name VARCHAR(100) NOT NULL UNIQUE,
client_id VARCHAR(255) NOT NULL,
client_secret_encrypted TEXT NOT NULL,
authorization_url TEXT NOT NULL,
token_url TEXT NOT NULL,
user_info_url TEXT NOT NULL,
scopes TEXT[] DEFAULT ARRAY['openid', 'profile', 'email'],
enabled BOOLEAN DEFAULT true,
created_at TIMESTAMP DEFAULT NOW(),
updated_at TIMESTAMP DEFAULT NOW()
);
CREATE INDEX idx_oauth_providers_name ON oauth_providers(name);
CREATE INDEX idx_oauth_providers_enabled ON oauth_providers(enabled) WHERE enabled = true;
```

### API Service Implementation
```typescript
// File: kms-frontend/src/services/apiService.ts
class APIService {
private baseURL: string;
private token: string | null = null;
constructor(baseURL: string) {
this.baseURL = baseURL;
}
async request<T>(endpoint: string, options: RequestInit = {}): Promise<T> {
const url = `${this.baseURL}${endpoint}`;

'X-User-Email': this.getUserEmail(),
...options.headers,
};
const response = await fetch(url, {
...options,
headers,
});
if (!response.ok) {
const error = await response.json().catch(() => ({}));
throw new APIError(error.message || 'Request failed', response.status);
}
return response.json();
}
// Application management
async getApplications(): Promise<Application[]> {

}
// Audit log access
async getAuditEvents(params: AuditQueryParams): Promise<AuditEvent[]> {
const queryString = new URLSearchParams(params).toString();
return this.request<AuditEvent[]>(`/api/audit/events?${queryString}`);
}
}
```
### Authentication Context
```typescript
// File: kms-frontend/src/contexts/AuthContext.tsx
interface AuthContextType {
user: User | null;
login: (email: string) => Promise<void>;
logout: () => void;
isAuthenticated: boolean;
isLoading: boolean;
}
export const AuthContext = React.createContext<AuthContextType | null>(null);
export const AuthProvider: React.FC<{ children: React.ReactNode }> = ({ children }) => {
const [user, setUser] = useState<User | null>(null);
const [isLoading, setIsLoading] = useState(true);
const login = async (email: string) => {
try {
setIsLoading(true);
const response = await apiService.login(email);
setUser({ email, token: response.token });
localStorage.setItem('kms_user', JSON.stringify({ email }));
} catch (error) {
throw error;
} finally {
setIsLoading(false);
}
};
// ... rest of implementation
};
```
---
## Configuration Management
### Configuration Interface
```go
// File: internal/config/config.go
type ConfigProvider interface {
GetString(key string) string
GetInt(key string) int
GetBool(key string) bool
GetDuration(key string) time.Duration
GetStringSlice(key string) []string
IsSet(key string) bool
Validate() error
GetDatabaseDSN() string
GetServerAddress() string
IsDevelopment() bool
IsProduction() bool
}
```
### Configuration Validation
```go
func (c *Config) Validate() error {
var errors []string
// Required configuration
required := []string{
"INTERNAL_HMAC_KEY",
"JWT_SECRET",
"AUTH_SIGNING_KEY",
"DB_HOST",
"DB_NAME",
}
for _, key := range required {
if !c.IsSet(key) {
errors = append(errors, fmt.Sprintf("required configuration %s is not set", key))
}
}
// Validate key lengths
if len(c.GetString("INTERNAL_HMAC_KEY")) < 32 {
errors = append(errors, "INTERNAL_HMAC_KEY must be at least 32 characters")
}
if len(errors) > 0 {
return fmt.Errorf("configuration validation failed: %s", strings.Join(errors, ", "))
}
return nil
}
```
### Environment Configuration
```bash
# Security Configuration
INTERNAL_HMAC_KEY=3924f352b7ea63b27db02bf4b0014f2961a5d2f7c27643853a4581bb3a5457cb
JWT_SECRET=7f5e11d55e957988b00ce002418680af384219ef98c50d08cbbbdd541978450c
AUTH_SIGNING_KEY=484f921b39c383e6b3e0cc5a7cef3c2cec3d7c8d474ab5102891dc4c2bf63a68
# Database Configuration
DB_HOST=postgres
DB_PORT=5432
DB_NAME=kms
DB_USER=postgres
DB_PASSWORD=postgres
# Feature Flags
RATE_LIMIT_ENABLED=true
CACHE_ENABLED=false
METRICS_ENABLED=true
SAML_ENABLED=false
```

## Implementation Best Practices
### Code Organization
1. **Follow clean architecture principles**
2. **Use dependency injection throughout**
3. **Implement comprehensive error handling**
4. **Add structured logging to all components**
5. **Write unit tests for business logic**
### Security Guidelines
1. **Always validate input at API boundaries**
2. **Use parameterized database queries**
3. **Implement proper authentication and authorization**
4. **Log all security-relevant events**
5. **Follow principle of least privilege**
### Performance Considerations
1. **Implement caching for frequently accessed data**
2. **Use database indexes appropriately**
3. **Monitor and optimize slow queries**
4. **Implement proper connection pooling**
5. **Use asynchronous operations where beneficial**
### Testing Strategy
1. **Unit tests for business logic**
2. **Integration tests for API endpoints**
3. **End-to-end tests for critical workflows**
4. **Load testing for performance validation**
5. **Security testing for vulnerability assessment**

# KMS Frontend - Key Management System
A modern React frontend for the Key Management System (KMS) API, built with TypeScript and Ant Design.
## Features
- **Dashboard**: System overview with health status and statistics
- **Application Management**: Create, view, edit, and delete applications
- **Token Management**: Create and manage static tokens with permissions
- **User Management**: Handle user authentication and token operations
- **Audit Logging**: Monitor system activities and security events
- **Responsive Design**: Mobile-friendly interface with Ant Design components
## Technology Stack
- **React 18** with TypeScript
- **Ant Design** for UI components
- **Axios** for API communication
- **React Router** for navigation
- **Day.js** for date handling
## Getting Started
### Prerequisites
- Node.js (v14 or higher)
- npm or yarn
- KMS API server running on `http://localhost:8080`
### Installation
1. Clone the repository:
```bash
git clone <repository-url>
cd kms-frontend
```
2. Install dependencies:
```bash
npm install
```
3. Configure environment variables:
```bash
cp .env.example .env
```
Edit `.env` to match your API configuration:
```
REACT_APP_API_URL=http://localhost:8080
REACT_APP_APP_NAME=KMS Frontend
REACT_APP_VERSION=1.0.0
```
4. Start the development server:
```bash
npm start
```
The application will be available at `http://localhost:3000`.
## Project Structure
```
src/
├── components/ # React components
│ ├── Applications.tsx # Application management
│ ├── Audit.tsx # Audit logging
│ ├── Dashboard.tsx # Main dashboard
│ ├── Login.tsx # Authentication
│ ├── Tokens.tsx # Token management
│ └── Users.tsx # User management
├── contexts/ # React contexts
│ └── AuthContext.tsx # Authentication context
├── services/ # API services
│ └── apiService.ts # KMS API client
├── App.tsx # Main application component
├── App.css # Custom styles
└── index.tsx # Application entry point
```
## API Integration
The frontend integrates with the KMS API and supports:
- **Health Checks**: Monitor API availability
- **Application CRUD**: Full application lifecycle management
- **Token Operations**: Create, verify, and manage tokens
- **User Authentication**: Login and token renewal flows
- **Audit Trails**: View system activity logs
## Authentication
The application uses a demo authentication system for development:
1. Enter any valid email address on the login screen
2. The system will simulate authentication and grant permissions
3. In production, integrate with your identity provider (OAuth2, SAML, etc.)
## Available Scripts
- `npm start` - Start development server
- `npm run build` - Build for production
- `npm test` - Run tests
- `npm run eject` - Eject from Create React App
## Configuration
### Environment Variables
- `REACT_APP_API_URL` - KMS API base URL
- `REACT_APP_APP_NAME` - Application name
- `REACT_APP_VERSION` - Application version
### API Configuration
The API service automatically includes the `X-User-Email` header for authentication. Configure your KMS API to accept this header for demo purposes.
## Features Overview
### Dashboard
- System health monitoring
- Application and token statistics
- Quick action shortcuts
### Applications
- Create new applications with configuration
- View application details and security settings
- Edit application properties
- Delete applications and associated tokens
### Tokens
- Create static tokens with specific permissions
- View token details and metadata
- Verify token validity and permissions
- Delete tokens when no longer needed
### Users
- Current user information display
- Initiate user authentication flows
- Renew user tokens
- Authentication method documentation
### Audit Log
- Comprehensive activity tracking
- Filter by date, user, action, and status
- Detailed event information
- Timeline view of recent activities
## Security Considerations
- All API communications should use HTTPS in production
- Tokens are displayed only once during creation
- Sensitive information is masked in the UI
- Audit logging tracks all user actions
## Development
### Adding New Features
1. Create new components in `src/components/`
2. Add API methods to `src/services/apiService.ts`
3. Update routing in `src/App.tsx`
4. Add navigation items to the sidebar menu
### Styling
The application uses Ant Design's theming system with custom CSS overrides in `App.css`. Follow Ant Design's design principles for consistency.
### Testing
Run the test suite with:
```bash
npm test
```
## Production Deployment
1. Build the application:
```bash
npm run build
```
2. Deploy the `build/` directory to your web server
3. Configure your web server to serve the React app
4. Ensure the KMS API is accessible from your production domain
5. Update environment variables for production
## Browser Support
- Chrome (latest)
- Firefox (latest)
- Safari (latest)
- Edge (latest)
