+# Server-Side Encryption with Customer-Provided Keys (SSE-C) Implementation
+
+This document describes the implementation of SSE-C support in SeaweedFS, addressing the feature request from [GitHub Discussion #5361](https://github.com/seaweedfs/seaweedfs/discussions/5361).
+
+## Overview
+
+SSE-C allows clients to provide their own encryption keys for server-side encryption of objects stored in SeaweedFS. The server encrypts the data using the customer-provided AES-256 key but does not store the key itself - only an MD5 hash of the key for validation purposes.
+
+## Implementation Details
+
+### Architecture
+
+The SSE-C implementation follows a transparent encryption/decryption pattern:
+
+1. **Upload (PUT/POST)**: Data is encrypted with the customer key before being stored
+2. **Download (GET/HEAD)**: Encrypted data is decrypted on-the-fly using the customer key
+3. **Metadata Storage**: Only the encryption algorithm and key MD5 are stored as metadata
+
+### Key Components
+
+#### 1. Constants and Headers (`weed/s3api/s3_constants/header.go`)
+- Added AWS-compatible SSE-C header constants
+- Support for both regular and copy-source SSE-C headers
+
+#### 2. Core SSE-C Logic (`weed/s3api/s3_sse_c.go`)
+- **SSECustomerKey**: Structure to hold customer encryption key and metadata
+- **SSECEncryptedReader**: Streaming encryption with AES-256-CTR mode
+- **SSECDecryptedReader**: Streaming decryption with IV extraction
+- **validateAndParseSSECHeaders**: Shared validation logic (DRY principle)
+- **ParseSSECHeaders**: Parse regular SSE-C headers
+- **ParseSSECCopySourceHeaders**: Parse copy-source SSE-C headers
+- Header validation and parsing functions
+- Metadata extraction and response handling
+
+#### 3. Error Handling (`weed/s3api/s3err/s3api_errors.go`)
+- New error codes for SSE-C validation failures
+- AWS-compatible error messages and HTTP status codes
+
+#### 4. S3 API Integration
+- **PUT Object Handler**: Encrypts data streams transparently
+- **GET Object Handler**: Decrypts data streams transparently
+- **HEAD Object Handler**: Validates keys and returns appropriate headers
+- **Metadata Storage**: Integrates with existing `SaveAmzMetaData` function
+
+### Encryption Scheme
+
+- **Algorithm**: AES-256-CTR (Counter mode)
+- **Key Size**: 256 bits (32 bytes)
+- **IV Generation**: Random 16-byte IV per object
+- **Storage Format**: `[IV][EncryptedData]` where IV is prepended to encrypted content
+
+### Metadata Storage
+
+SSE-C metadata is stored in the filer's extended attributes:
+```
+x-amz-server-side-encryption-customer-algorithm: "AES256"
+x-amz-server-side-encryption-customer-key-md5: "<md5-hash-of-key>"
+```
+
+## API Compatibility
+
+### Required Headers for Encryption (PUT/POST)
+```
+x-amz-server-side-encryption-customer-algorithm: AES256
+x-amz-server-side-encryption-customer-key: <base64-encoded-256-bit-key>
+x-amz-server-side-encryption-customer-key-md5: <md5-hash-of-key>
+```
+
+### Required Headers for Decryption (GET/HEAD)
+Same headers as encryption - the server validates the key MD5 matches.
+
+### Copy Operations
+Support for copy-source SSE-C headers:
+```
+x-amz-copy-source-server-side-encryption-customer-algorithm
+x-amz-copy-source-server-side-encryption-customer-key  
+x-amz-copy-source-server-side-encryption-customer-key-md5
+```
+
+## Error Handling
+
+The implementation provides AWS-compatible error responses:
+
+- **InvalidEncryptionAlgorithmError**: Non-AES256 algorithm specified
+- **InvalidArgument**: Invalid key format, size, or MD5 mismatch
+- **Missing customer key**: Object encrypted but no key provided
+- **Unnecessary customer key**: Object not encrypted but key provided
+
+## Security Considerations
+
+1. **Key Management**: Customer keys are never stored - only MD5 hashes for validation
+2. **IV Randomness**: Fresh random IV generated for each object
+3. **Transparent Security**: Volume servers never see unencrypted data
+4. **Key Validation**: Strict validation of key format, size, and MD5
+
+## Testing
+
+Comprehensive test suite covers:
+- Header validation and parsing (regular and copy-source)
+- Encryption/decryption round-trip
+- Error condition handling  
+- Metadata extraction
+- Code reuse validation (DRY principle)
+- AWS S3 compatibility
+
+Run tests with:
+```bash
+go test -v ./weed/s3api
+
+## Usage Example
+
+### Upload with SSE-C
+```bash
+# Generate a 256-bit key
+KEY=$(openssl rand -base64 32)
+KEY_MD5=$(echo -n "$KEY" | base64 -d | openssl dgst -md5 -binary | base64)
+
+# Upload object with SSE-C
+curl -X PUT "http://localhost:8333/bucket/object" \
+  -H "x-amz-server-side-encryption-customer-algorithm: AES256" \
+  -H "x-amz-server-side-encryption-customer-key: $KEY" \
+  -H "x-amz-server-side-encryption-customer-key-md5: $KEY_MD5" \
+  --data-binary @file.txt
+```
+
+### Download with SSE-C
+```bash
+# Download object with SSE-C (same key required)
+curl "http://localhost:8333/bucket/object" \
+  -H "x-amz-server-side-encryption-customer-algorithm: AES256" \
+  -H "x-amz-server-side-encryption-customer-key: $KEY" \
+  -H "x-amz-server-side-encryption-customer-key-md5: $KEY_MD5"
+```
+
+## Integration Points
+
+### Existing SeaweedFS Features
+- **Filer Metadata**: Extends existing metadata storage
+- **Volume Servers**: No changes required - store encrypted data transparently
+- **S3 API**: Integrates seamlessly with existing handlers
+- **Versioning**: Compatible with object versioning
+- **Multipart Upload**: Ready for multipart upload integration
+
+### Future Enhancements
+- **SSE-S3**: Server-managed encryption keys
+- **SSE-KMS**: External key management service integration
+- **Performance Optimization**: Hardware acceleration for encryption
+- **Compliance**: Enhanced audit logging for encrypted objects
+
+## File Changes Summary
+
+1. **`weed/s3api/s3_constants/header.go`** - Added SSE-C header constants
+2. **`weed/s3api/s3_sse_c.go`** - Core SSE-C implementation (NEW)
+3. **`weed/s3api/s3_sse_c_test.go`** - Comprehensive test suite (NEW)
+4. **`weed/s3api/s3err/s3api_errors.go`** - Added SSE-C error codes

+
+- **Encryption Overhead**: Minimal CPU impact with efficient AES-CTR streaming
+- **Memory Usage**: Constant memory usage via streaming encryption/decryption
+- **Storage Overhead**: 16 bytes per object for IV storage
+- **Network**: No additional network overhead

+# 🔐 SeaweedFS KMS Integration Tests
+
+This directory contains comprehensive integration tests for SeaweedFS Server-Side Encryption (SSE) with Key Management Service (KMS) providers. The tests validate the complete encryption/decryption workflow using **OpenBao** (open source fork of HashiCorp Vault) as the KMS provider.
+
+## 🎯 Overview
+
+The KMS integration tests simulate **AWS KMS** functionality using **OpenBao**, providing:
+
+- ✅ **Production-grade KMS testing** with real encryption/decryption operations
+- ✅ **S3 API compatibility testing** with SSE-KMS headers and bucket encryption
+- ✅ **Per-bucket KMS configuration** validation
+- ✅ **Performance benchmarks** for KMS operations
+- ✅ **Error handling and edge case** coverage
+- ✅ **End-to-end workflows** from S3 API to KMS provider
+
+## 🏗️ Architecture

+```
+
+## 🧪 Test Components
+
+### 1. **OpenBao KMS Provider** (`openbao_integration_test.go`)
+
+**What it tests:**
+- KMS provider registration and initialization  
+- Data key generation using Transit engine
+- Encryption/decryption of data keys
+- Key metadata and validation
+- Error handling (invalid tokens, missing keys, etc.)
+- Multiple key scenarios
+- Performance benchmarks
+
+**Key test cases:**

+TestOpenBaoKMSProvider_Integration
+TestOpenBaoKMSProvider_ErrorHandling  
+TestKMSManager_WithOpenBao
+BenchmarkOpenBaoKMS_GenerateDataKey
+BenchmarkOpenBaoKMS_Decrypt
+```
+
+### 2. **S3 API Integration** (`test_s3_kms.sh`)
+
+**What it tests:**
+- Bucket encryption configuration via S3 API
+- Default bucket encryption behavior
+- Explicit SSE-KMS headers in PUT operations
+- Object upload/download with encryption
+- Multipart uploads with KMS encryption
+- Encryption metadata in object headers
+- Cross-bucket KMS provider isolation
+
+**Key scenarios:**
+```bash
+# Bucket encryption setup
+aws s3api put-bucket-encryption --bucket test-openbao \
+  --server-side-encryption-configuration '{
+    "Rules": [{
+      "ApplyServerSideEncryptionByDefault": {
+        "SSEAlgorithm": "aws:kms", 
+        "KMSMasterKeyID": "test-key-1"
+      }
+    }]
+  }'
+
+# Object upload with encryption
+aws s3 cp file.txt s3://test-openbao/encrypted-file.txt \
+  --sse aws:kms --sse-kms-key-id "test-key-2"
+```
+
+### 3. **Docker Environment** (`docker-compose.yml`)
+
+**Services:**
+- **OpenBao** - KMS provider (port 8200)
+- **Vault** - Alternative KMS (port 8201)  
+- **SeaweedFS Master** - Cluster coordination (port 9333)
+- **SeaweedFS Volume** - Data storage (port 8080)
+- **SeaweedFS Filer** - S3 API endpoint (port 8333)
+
+### 4. **Configuration** (`filer.toml`)
+
+**KMS Configuration:**
+```toml
+[kms]
+default_provider = "openbao-test"
+
+[kms.providers.openbao-test]
+type = "openbao"
+address = "http://openbao:8200"
+token = "root-token-for-testing"
+transit_path = "transit"
+
+[kms.buckets.test-openbao]
+provider = "openbao-test"
+```
+
+## 📊 Test Data
+
+### Encryption Keys Created
+
+The setup script creates these test keys in OpenBao:
+
+| Key Name | Type | Purpose |
+|----------|------|---------|
+| `test-key-1` | AES256-GCM96 | Basic operations |  
+| `test-key-2` | AES256-GCM96 | Multi-key scenarios |
+| `seaweedfs-test-key` | AES256-GCM96 | Integration testing |
+| `bucket-default-key` | AES256-GCM96 | Default bucket encryption |
+| `high-security-key` | AES256-GCM96 | Security testing |
+| `performance-key` | AES256-GCM96 | Performance benchmarks |
+| `multipart-key` | AES256-GCM96 | Multipart upload testing |
+
+### Test Buckets
+
+| Bucket Name | KMS Provider | Purpose |
+|-------------|--------------|---------|
+| `test-openbao` | openbao-test | OpenBao integration |
+| `test-vault` | vault-test | Vault compatibility |
+| `test-local` | local-test | Local KMS testing |  
+| `secure-data` | openbao-test | High security scenarios |
+
+## 🔧 Configuration Options
+
+### Environment Variables
+
+```bash
+# OpenBao configuration
+export OPENBAO_ADDR="http://127.0.0.1:8200"
+export OPENBAO_TOKEN="root-token-for-testing"
+
+# SeaweedFS configuration  
+export SEAWEEDFS_S3_ENDPOINT="http://127.0.0.1:8333"
+export ACCESS_KEY="any"
+export SECRET_KEY="any"
+
+# Test configuration
+export TEST_TIMEOUT="5m"
+```
+
+### Makefile Targets
+
+| Target | Description |
+|--------|-------------|
+| `make help` | Show available commands |
+| `make setup` | Set up test environment |
+| `make test` | Run all tests |
+| `make test-unit` | Run unit tests only |
+| `make test-integration` | Run integration tests |
+| `make test-e2e` | Run end-to-end tests |
+| `make clean` | Clean up environment |
+| `make logs` | Show service logs |
+| `make status` | Check service status |
+
+## 🧩 How It Works
+
+### 1. **KMS Provider Registration**
+
+OpenBao provider is automatically registered via `init()`:
+
+```go
+func init() {
+    seaweedkms.RegisterProvider("openbao", NewOpenBaoKMSProvider)
+    seaweedkms.RegisterProvider("vault", NewOpenBaoKMSProvider) // Alias
+}
+```
+
+### 2. **Data Key Generation Flow**
+
+```
+1. S3 PUT with SSE-KMS headers
+2. SeaweedFS extracts KMS key ID  
+3. KMSManager routes to OpenBao provider
+4. OpenBao generates random data key
+5. OpenBao encrypts data key with master key
+6. SeaweedFS encrypts object with data key
+7. Encrypted data key stored in metadata
+```
+
+### 3. **Decryption Flow**
+
+```
+1. S3 GET request for encrypted object
+2. SeaweedFS extracts encrypted data key from metadata
+3. KMSManager routes to OpenBao provider
+4. OpenBao decrypts data key with master key
+5. SeaweedFS decrypts object with data key
+6. Plaintext object returned to client
+```
+
+## 🔍 Troubleshooting
+
+### Common Issues
+
+**OpenBao not starting:**
+```bash
+# Check if port 8200 is in use
+lsof -i :8200
+
+# Check Docker logs
+docker-compose logs openbao
+```
+
+**KMS provider not found:**
+```bash
+# Verify provider registration
+go test -v -run TestProviderRegistration ./test/kms/
+
+# Check imports in filer_kms.go
+grep -n "kms/" weed/command/filer_kms.go
+```
+
+**S3 API connection refused:**
+```bash  
+# Check SeaweedFS services
+make status
+
+# Wait for services to be ready
+./wait_for_services.sh
+```
+
+### Debug Commands
+
+```bash
+# Test OpenBao directly
+curl -H "X-Vault-Token: root-token-for-testing" \
+  http://127.0.0.1:8200/v1/sys/health
+
+# Test transit engine
+curl -X POST \
+  -H "X-Vault-Token: root-token-for-testing" \
+  -d '{"plaintext":"SGVsbG8gV29ybGQ="}' \
+  http://127.0.0.1:8200/v1/transit/encrypt/test-key-1
+
+# Test S3 API
+aws s3 ls --endpoint-url http://127.0.0.1:8333
+```
+
+## 🎯 AWS KMS Integration Testing
+
+This test suite **simulates AWS KMS behavior** using OpenBao, enabling:
+
+### ✅ **Compatibility Validation**
+
+- **S3 API compatibility** - Same headers, same behavior as AWS S3
+- **KMS API patterns** - GenerateDataKey, Decrypt, DescribeKey operations  
+- **Error codes** - AWS-compatible error responses
+- **Encryption context** - Proper context handling and validation
+
+### ✅ **Production Readiness Testing**
+
+- **Key rotation scenarios** - Multiple keys per bucket
+- **Performance characteristics** - Latency and throughput metrics
+- **Error recovery** - Network failures, invalid keys, timeout handling
+- **Security validation** - Encryption/decryption correctness
+
+### ✅ **Integration Patterns**
+
+- **Bucket-level configuration** - Different KMS keys per bucket
+- **Cross-region simulation** - Multiple KMS providers
+- **Caching behavior** - Data key caching validation  
+- **Metadata handling** - Encrypted metadata storage
+
+## 📈 Performance Expectations
+
+**Typical performance metrics** (local testing):
+
+- **Data key generation**: ~50-100ms (including network roundtrip)
+- **Data key decryption**: ~30-50ms (cached provider instance)
+- **Object encryption**: ~1-5ms per MB (AES-256-GCM)
+- **S3 PUT with SSE-KMS**: +100-200ms overhead vs. unencrypted
+
+## 🚀 Production Deployment
+
+After successful integration testing, deploy with real KMS providers:
+
+```toml
+[kms.providers.aws-prod]
+type = "aws"
+region = "us-east-1"
+# IAM roles preferred over access keys
+
+[kms.providers.azure-prod]  
+type = "azure"
+vault_url = "https://prod-vault.vault.azure.net/"
+use_default_creds = true # Managed identity
+
+[kms.providers.gcp-prod]
+type = "gcp" 
+project_id = "prod-project"
+use_default_credentials = true # Service account
+```
+
+## 🎉 Success Criteria
+
+Tests pass when:
+
+- ✅ All KMS providers register successfully
+- ✅ Data key generation/decryption works end-to-end  
+- ✅ S3 API encryption headers are handled correctly
+- ✅ Bucket-level KMS configuration is respected
+- ✅ Multipart uploads maintain encryption consistency
+- ✅ Performance meets acceptable thresholds
+- ✅ Error scenarios are handled gracefully
+
+---

+# SeaweedFS S3 IAM Integration with Docker Compose
+
+This directory contains a complete Docker Compose setup for testing SeaweedFS S3 IAM integration with Keycloak OIDC authentication.
+
+## 🚀 Quick Start
+
+1. **Build local SeaweedFS image:**
+   ```bash
+   make -f Makefile.docker docker-build
+   ```
+
+2. **Start the environment:**
+   ```bash
+   make -f Makefile.docker docker-up
+   ```
+
+3. **Run the tests:**
+   ```bash
+   make -f Makefile.docker docker-test
+   ```
+
+4. **Stop the environment:**
+   ```bash
+   make -f Makefile.docker docker-down
+   ```
+
+## 📋 What's Included
+
+The Docker Compose setup includes:
+
+- **🔐 Keycloak** - Identity provider with OIDC support
+- **🎯 SeaweedFS Master** - Metadata management
+- **💾 SeaweedFS Volume** - Data storage
+- **📁 SeaweedFS Filer** - File system interface
+- **📊 SeaweedFS S3** - S3-compatible API with IAM integration
+- **🔧 Keycloak Setup** - Automated realm and user configuration
+
+## 🌐 Service URLs
+
+After starting with `docker-up`, services are available at:
+
+| Service | URL | Credentials |
+|---------|-----|-------------|
+| 🔐 Keycloak Admin | http://localhost:8080 | admin/admin |
+| 📊 S3 API | http://localhost:8333 | JWT tokens |
+| 📁 Filer | http://localhost:8888 | - |
+| 🎯 Master | http://localhost:9333 | - |
+
+## 👥 Test Users
+
+The setup automatically creates test users in Keycloak:
+
+| Username | Password | Role | Permissions |
+|----------|----------|------|-------------|
+| admin-user | adminuser123 | s3-admin | Full S3 access |
+| read-user | readuser123 | s3-read-only | Read-only access |
+| write-user | writeuser123 | s3-read-write | Read and write |
+| write-only-user | writeonlyuser123 | s3-write-only | Write only |
+
+## 🧪 Running Tests
+
+### All Tests
+```bash
+make -f Makefile.docker docker-test
+```
+
+### Specific Test Categories
+```bash
+# Authentication tests only
+make -f Makefile.docker docker-test-auth
+
+# Role mapping tests only  
+make -f Makefile.docker docker-test-roles
+
+# S3 operations tests only
+make -f Makefile.docker docker-test-s3ops
+```
+
+### Single Test
+```bash
+make -f Makefile.docker docker-test-single TEST_NAME=TestKeycloakAuthentication
+```
+
+## 🔧 Development Workflow
+
+### Complete workflow (recommended)
+```bash
+# Build, start, test, and clean up
+make -f Makefile.docker docker-build
+make -f Makefile.docker docker-dev
+```
+This runs: build → down → up → test
+
+### Using Published Images (Alternative)
+If you want to use published Docker Hub images instead of building locally:
+```bash
+export SEAWEEDFS_IMAGE=chrislusf/seaweedfs:latest
+make -f Makefile.docker docker-up
+```
+
+### Manual steps
+```bash
+# Build image (required first time, or after code changes)
+make -f Makefile.docker docker-build
+
+# Start services
+make -f Makefile.docker docker-up
+
+# Watch logs
+make -f Makefile.docker docker-logs
+
+# Check status
+make -f Makefile.docker docker-status
+
+# Run tests
+make -f Makefile.docker docker-test
+
+# Stop services  
+make -f Makefile.docker docker-down
+```
+
+## 🔍 Debugging
+
+### View logs
+```bash
+# All services
+make -f Makefile.docker docker-logs
+
+# S3 service only (includes role mapping debug)
+make -f Makefile.docker docker-logs-s3  
+
+# Keycloak only
+make -f Makefile.docker docker-logs-keycloak
+```
+
+### Get shell access
+```bash
+# S3 container
+make -f Makefile.docker docker-shell-s3
+
+# Keycloak container
+make -f Makefile.docker docker-shell-keycloak
+```
+

+├── docker-compose.yml          # Main Docker Compose configuration
+├── Makefile.docker             # Docker-specific Makefile

+```
+
+## 🔄 Configuration
+
+### IAM Configuration
+The `setup_keycloak_docker.sh` script automatically generates `iam_config.json` with:
+
+- **OIDC Provider**: Keycloak configuration with proper container networking
+- **Role Mapping**: Maps Keycloak roles to SeaweedFS IAM roles
+- **Policies**: Defines S3 permissions for each role
+- **Trust Relationships**: Allows Keycloak users to assume SeaweedFS roles
+
+### Role Mapping Rules
+```json
+{
+  "claim": "roles",
+  "value": "s3-admin", 
+  "role": "arn:seaweed:iam::role/KeycloakAdminRole"
+}
+```
+
+## 🐛 Troubleshooting
+
+### Services not starting
+```bash
+# Check service status
+make -f Makefile.docker docker-status
+
+# View logs for specific service
+docker-compose -p seaweedfs-iam-test logs <service-name>
+```
+
+### Keycloak setup issues
+```bash  
+# Re-run Keycloak setup manually
+make -f Makefile.docker docker-keycloak-setup
+
+# Check Keycloak logs
+make -f Makefile.docker docker-logs-keycloak
+```
+
+### Role mapping not working
+```bash
+# Check S3 logs for role mapping debug messages
+make -f Makefile.docker docker-logs-s3 | grep -i "role\|claim\|mapping"
+```
+
+### Port conflicts
+If ports are already in use, modify `docker-compose.yml`:
+```yaml
+ports:
+  - "8081:8080"  # Change external port
+```
+
+## 🧹 Cleanup
+
+```bash
+# Stop containers and remove volumes
+make -f Makefile.docker docker-down
+
+# Complete cleanup (containers, volumes, images)
+make -f Makefile.docker docker-clean
+```
+
+## 🎯 Key Features
+
+- **Local Code Testing**: Uses locally built SeaweedFS images to test current code
+- **Isolated Environment**: No conflicts with local services
+- **Consistent Networking**: Services communicate via Docker network
+- **Automated Setup**: Keycloak realm and users created automatically
+- **Debug Logging**: Verbose logging enabled for troubleshooting  
+- **Health Checks**: Proper service dependency management
+- **Volume Persistence**: Data persists between restarts (until docker-down)
+
+## 🚦 CI/CD Integration
+
+For automated testing:
+
+```bash
+# Build image, run tests with proper cleanup
+make -f Makefile.docker docker-build
+make -f Makefile.docker docker-up
+make -f Makefile.docker docker-wait-healthy  
+make -f Makefile.docker docker-test
+make -f Makefile.docker docker-down
+```

+This directory contains comprehensive integration tests for the SeaweedFS S3 API with Advanced IAM (Identity and Access Management) system integration.
+
+## Overview

+- **JWT Authentication**: OIDC token-based authentication with S3 API
+- **Policy Enforcement**: Fine-grained access control for S3 operations
+- **Stateless Session Management**: JWT-based session token validation and expiration (no external storage)
+- **Role-Based Access Control (RBAC)**: IAM roles with different permission levels
+- **Bucket Policies**: Resource-based access control integration
+- **Multipart Upload IAM**: Policy enforcement for multipart operations
+- **Contextual Policies**: IP-based, time-based, and conditional access control
+- **Presigned URLs**: IAM-integrated temporary access URL generation
+
+## Test Architecture
+
+### Components Tested
+
+1. **S3 API Gateway** - SeaweedFS S3-compatible API server with IAM integration
+2. **IAM Manager** - Core IAM orchestration and policy evaluation
+3. **STS Service** - Security Token Service for temporary credentials
+4. **Policy Engine** - AWS IAM-compatible policy evaluation
+5. **Identity Providers** - OIDC and LDAP authentication providers
+6. **Policy Store** - Persistent policy storage using SeaweedFS filer
+
+### Test Framework
+
+- **S3IAMTestFramework**: Comprehensive test utilities and setup
+- **Mock OIDC Provider**: In-memory OIDC server with JWT signing

+```
+
+## Extending Tests
+
+### Adding New Test Scenarios
+
+1. **Create Test Function**:
+   ```go
+   func TestS3IAMNewFeature(t *testing.T) {
+       framework := NewS3IAMTestFramework(t)
+       defer framework.Cleanup()
+       
+       // Test implementation
+   }
+   ```
+
+2. **Use Test Framework**:
+   ```go
+   // Create authenticated S3 client
+   s3Client, err := framework.CreateS3ClientWithJWT("user", "TestRole")
+   require.NoError(t, err)
+   
+   // Test S3 operations
+   err = framework.CreateBucket(s3Client, "test-bucket")
+   require.NoError(t, err)
+   ```
+
+3. **Add to Makefile**:
+   ```makefile
+   test-new-feature: ## Test new feature
+   	go test -v -run TestS3IAMNewFeature ./...
+   ```
+
+### Creating Custom Policies
+
+Add policies to `test_config.json`:
+
+```json
+{
+  "policies": {
+    "CustomPolicy": {
+      "Version": "2012-10-17",
+      "Statement": [
+        {
+          "Effect": "Allow",
+          "Action": ["s3:GetObject"],
+          "Resource": ["arn:seaweed:s3:::specific-bucket/*"],
+          "Condition": {
+            "StringEquals": {
+              "s3:prefix": ["allowed-prefix/"]
+            }
+          }
+        }
+      ]
+    }
+  }
+}
+```
+
+### Adding Identity Providers
+
+1. **Mock Provider Setup**:
+   ```go
+   // In test framework
+   func (f *S3IAMTestFramework) setupCustomProvider() {
+       provider := custom.NewCustomProvider("test-custom")
+       // Configure and register
+   }
+   ```
+
+2. **Configuration**:
+   ```json
+   {
+     "providers": {
+       "custom": {
+         "test-custom": {
+           "endpoint": "http://localhost:8080",
+           "clientId": "custom-client"
+         }
+       }
+     }
+   }
+   ```
+
+## Troubleshooting
+
+### Common Issues
+
+#### 1. Services Not Starting
+```bash
+# Check if ports are available
+netstat -an | grep -E "(8333|8888|9333|8080)"
+
+# Check service logs
+make logs
+
+# Try different ports
+export S3_PORT=18333
+make start-services
+```
+
+#### 2. JWT Token Issues
+```bash
+# Verify OIDC mock server
+curl http://localhost:8080/.well-known/openid_configuration
+
+# Check JWT token format in logs
+make logs | grep -i jwt
+```
+
+#### 3. Permission Denied Errors
+```bash
+# Verify IAM configuration
+cat test_config.json | jq '.policies'
+
+# Check policy evaluation in logs  
+export LOG_LEVEL=4
+make start-services
+```
+
+#### 4. Test Timeouts
+```bash
+# Increase timeout
+export TEST_TIMEOUT=60m
+make test
+
+# Run individual tests
+make test-auth
+```
+
+### Debug Mode
+
+Start services in debug mode to inspect manually:
+
+```bash
+# Start and keep running
+make debug
+
+# In another terminal, run specific operations
+aws s3 ls --endpoint-url http://localhost:8333
+
+# Stop when done (Ctrl+C in debug terminal)
+```
+
+### Log Analysis
+
+```bash
+# Service-specific logs
+tail -f weed-s3.log       # S3 API server
+tail -f weed-filer.log    # Filer (IAM storage)  
+tail -f weed-master.log   # Master server
+tail -f weed-volume.log   # Volume server
+
+# Filter for IAM-related logs
+make logs | grep -i iam
+make logs | grep -i jwt
+make logs | grep -i policy
+```
+
+## Performance Testing
+
+### Benchmarks
+
+```bash
+# Run performance benchmarks
+make benchmark
+
+# Profile memory usage  
+go test -bench=. -memprofile=mem.prof
+go tool pprof mem.prof
+```
+
+### Load Testing
+
+For load testing with IAM:
+
+1. **Create Multiple Clients**:
+   ```go
+   // Generate multiple JWT tokens
+   tokens := framework.GenerateMultipleJWTTokens(100)
+   
+   // Create concurrent clients
+   var wg sync.WaitGroup
+   for _, token := range tokens {
+       wg.Add(1)
+       go func(token string) {
+           defer wg.Done()
+           // Perform S3 operations
+       }(token)
+   }
+   wg.Wait()
+   ```
+
+2. **Measure Performance**:
+   ```bash
+   # Run with verbose output
+   go test -v -bench=BenchmarkS3IAMOperations
+   ```
+

+# Distributed STS Service for SeaweedFS S3 Gateway
+
+This document explains how to configure and deploy the STS (Security Token Service) for distributed SeaweedFS S3 Gateway deployments with consistent identity provider configurations.
+
+## Problem Solved
+
+Previously, identity providers had to be **manually registered** on each S3 gateway instance, leading to:
+
+- ❌ **Inconsistent authentication**: Different instances might have different providers
+- ❌ **Manual synchronization**: No guarantee all instances have same provider configs
+- ❌ **Authentication failures**: Users getting different responses from different instances
+- ❌ **Operational complexity**: Difficult to manage provider configurations at scale
+
+## Solution: Configuration-Driven Providers
+
+The STS service now supports **automatic provider loading** from configuration files, ensuring:
+
+- ✅ **Consistent providers**: All instances load identical providers from config
+- ✅ **Automatic synchronization**: Configuration-driven, no manual registration needed
+- ✅ **Reliable authentication**: Same behavior from all instances
+- ✅ **Easy management**: Update config file, restart services
+
+## Configuration Schema
+
+### Basic STS Configuration
+
+```json
+{
+  "sts": {
+    "tokenDuration": "1h",
+    "maxSessionLength": "12h", 
+    "issuer": "seaweedfs-sts",
+    "signingKey": "base64-encoded-signing-key-32-chars-min"
+  }
+}
+```
+
+**Note**: The STS service uses a **stateless JWT design** where all session information is embedded directly in the JWT token. No external session storage is required.
+
+### Configuration-Driven Providers
+
+```json
+{
+  "sts": {
+    "tokenDuration": "1h",
+    "maxSessionLength": "12h",
+    "issuer": "seaweedfs-sts",
+    "signingKey": "base64-encoded-signing-key",
+    "providers": [
+      {
+        "name": "keycloak-oidc",
+        "type": "oidc", 
+        "enabled": true,
+        "config": {
+          "issuer": "https://keycloak.company.com/realms/seaweedfs",
+          "clientId": "seaweedfs-s3",
+          "clientSecret": "super-secret-key",
+          "jwksUri": "https://keycloak.company.com/realms/seaweedfs/protocol/openid-connect/certs",
+          "scopes": ["openid", "profile", "email", "roles"],
+          "claimsMapping": {
+            "usernameClaim": "preferred_username",
+            "groupsClaim": "roles"
+          }
+        }
+      },
+      {
+        "name": "backup-oidc",
+        "type": "oidc",
+        "enabled": false,
+        "config": {
+          "issuer": "https://backup-oidc.company.com",
+          "clientId": "seaweedfs-backup"
+        }
+      },
+      {
+        "name": "dev-mock-provider",
+        "type": "mock",
+        "enabled": true,
+        "config": {
+          "issuer": "http://localhost:9999",
+          "clientId": "mock-client"
+        }
+      }
+    ]
+  }
+}
+```
+
+## Supported Provider Types
+
+### 1. OIDC Provider (`"type": "oidc"`)
+
+For production authentication with OpenID Connect providers like Keycloak, Auth0, Google, etc.
+
+**Required Configuration:**
+- `issuer`: OIDC issuer URL
+- `clientId`: OAuth2 client ID
+
+**Optional Configuration:**
+- `clientSecret`: OAuth2 client secret (for confidential clients)
+- `jwksUri`: JSON Web Key Set URI (auto-discovered if not provided)
+- `userInfoUri`: UserInfo endpoint URI (auto-discovered if not provided)
+- `scopes`: OAuth2 scopes to request (default: `["openid"]`)
+- `claimsMapping`: Map OIDC claims to identity attributes
+
+**Example:**
+```json
+{
+  "name": "corporate-keycloak",
+  "type": "oidc",
+  "enabled": true,
+  "config": {
+    "issuer": "https://sso.company.com/realms/production",
+    "clientId": "seaweedfs-prod",
+    "clientSecret": "confidential-secret", 
+    "scopes": ["openid", "profile", "email", "groups"],
+    "claimsMapping": {
+      "usernameClaim": "preferred_username",
+      "groupsClaim": "groups",
+      "emailClaim": "email"
+    }
+  }
+}
+```
+
+### 2. Mock Provider (`"type": "mock"`)
+
+For development, testing, and staging environments.
+
+**Configuration:**
+- `issuer`: Mock issuer URL (default: `http://localhost:9999`)
+- `clientId`: Mock client ID
+
+**Example:**
+```json
+{
+  "name": "dev-mock",
+  "type": "mock", 
+  "enabled": true,
+  "config": {
+    "issuer": "http://dev-mock:9999",
+    "clientId": "dev-client"
+  }
+}
+```
+
+**Built-in Test Tokens:**
+- `valid_test_token`: Returns test user with developer groups
+- `valid-oidc-token`: Compatible with integration tests
+- `expired_token`: Returns token expired error
+- `invalid_token`: Returns invalid token error
+
+### 3. Future Provider Types
+
+The factory pattern supports easy addition of new provider types:
+
+- `"type": "ldap"`: LDAP/Active Directory authentication
+- `"type": "saml"`: SAML 2.0 authentication  
+- `"type": "oauth2"`: Generic OAuth2 providers
+- `"type": "custom"`: Custom authentication backends
+
+## Deployment Patterns
+
+### Single Instance (Development)
+
+```bash
+# Standard deployment with config-driven providers
+weed s3 -filer=localhost:8888 -port=8333 -iam.config=/path/to/sts_config.json
+```
+
+### Multiple Instances (Production)
+
+```bash
+# Instance 1 
+weed s3 -filer=prod-filer:8888 -port=8333 -iam.config=/shared/sts_distributed.json
+
+# Instance 2
+weed s3 -filer=prod-filer:8888 -port=8334 -iam.config=/shared/sts_distributed.json
+
+# Instance N
+weed s3 -filer=prod-filer:8888 -port=833N -iam.config=/shared/sts_distributed.json
+```
+
+**Critical Requirements for Distributed Deployment:**
+
+1. **Identical Configuration Files**: All instances must use the exact same configuration file
+2. **Same Signing Keys**: All instances must have identical `signingKey` values
+3. **Same Issuer**: All instances must use the same `issuer` value
+
+**Note**: STS now uses stateless JWT tokens, eliminating the need for shared session storage.
+
+### High Availability Setup
+
+```yaml
+# docker-compose.yml for production deployment
+services:
+  filer:
+    image: seaweedfs/seaweedfs:latest
+    command: "filer -master=master:9333"
+    volumes:
+      - filer-data:/data
+    
+  s3-gateway-1:
+    image: seaweedfs/seaweedfs:latest
+    command: "s3 -filer=filer:8888 -port=8333 -iam.config=/config/sts_distributed.json"
+    ports:
+      - "8333:8333"
+    volumes:
+      - ./sts_distributed.json:/config/sts_distributed.json:ro
+    depends_on: [filer]
+    
+  s3-gateway-2:
+    image: seaweedfs/seaweedfs:latest 
+    command: "s3 -filer=filer:8888 -port=8333 -iam.config=/config/sts_distributed.json"
+    ports:
+      - "8334:8333"
+    volumes:
+      - ./sts_distributed.json:/config/sts_distributed.json:ro
+    depends_on: [filer]
+    
+  s3-gateway-3:
+    image: seaweedfs/seaweedfs:latest
+    command: "s3 -filer=filer:8888 -port=8333 -iam.config=/config/sts_distributed.json"
+    ports:
+      - "8335:8333"
+    volumes:
+      - ./sts_distributed.json:/config/sts_distributed.json:ro
+    depends_on: [filer]
+    
+  load-balancer:
+    image: nginx:alpine
+    ports:
+      - "80:80"
+    volumes:
+      - ./nginx.conf:/etc/nginx/nginx.conf:ro
+    depends_on: [s3-gateway-1, s3-gateway-2, s3-gateway-3]
+```
+
+## Authentication Flow
+
+### 1. OIDC Authentication Flow
+
+```
+1. User authenticates with OIDC provider (Keycloak, Auth0, etc.)
+   ↓
+2. User receives OIDC JWT token from provider
+   ↓  
+3. User calls SeaweedFS STS AssumeRoleWithWebIdentity
+   POST /sts/assume-role-with-web-identity
+   {
+     "RoleArn": "arn:seaweed:iam::role/S3AdminRole",
+     "WebIdentityToken": "eyJ0eXAiOiJKV1QiLCJhbGc...",
+     "RoleSessionName": "user-session"
+   }
+   ↓
+4. STS validates OIDC token with configured provider
+   - Verifies JWT signature using provider's JWKS
+   - Validates issuer, audience, expiration
+   - Extracts user identity and groups
+   ↓
+5. STS checks role trust policy
+   - Verifies user/groups can assume the requested role
+   - Validates conditions in trust policy
+   ↓
+6. STS generates temporary credentials
+   - Creates temporary access key, secret key, session token
+   - Session token is signed JWT with all session information embedded (stateless)
+   ↓
+7. User receives temporary credentials
+   {
+     "Credentials": {
+       "AccessKeyId": "AKIA...",
+       "SecretAccessKey": "base64-secret",
+       "SessionToken": "eyJ0eXAiOiJKV1QiLCJhbGc...",
+       "Expiration": "2024-01-01T12:00:00Z"
+     }
+   }
+   ↓

+
+## Operational Best Practices
+
+### 1. Configuration Management
+
+- **Version Control**: Store configurations in Git with proper versioning
+- **Environment Separation**: Use separate configs for dev/staging/production
+- **Secret Management**: Use environment variable substitution for secrets
+- **Configuration Validation**: Test configurations before deployment
+
+### 2. Security Considerations
+
+- **Signing Key Security**: Use strong, randomly generated signing keys (32+ bytes)
+- **Key Rotation**: Implement signing key rotation procedures
+- **Secret Storage**: Store client secrets in secure secret management systems
+- **TLS Encryption**: Always use HTTPS for OIDC providers in production
+
+### 3. Monitoring and Troubleshooting
+
+- **Provider Health**: Monitor OIDC provider availability and response times
+- **Session Metrics**: Track active sessions, token validation errors
+- **Configuration Drift**: Alert on configuration inconsistencies between instances
+- **Authentication Logs**: Log authentication attempts for security auditing
+
+### 4. Capacity Planning
+
+- **Provider Performance**: Monitor OIDC provider response times and rate limits
+- **Token Validation**: Monitor JWT validation performance and caching
+- **Memory Usage**: Monitor JWT token validation caching and provider metadata
+
+## Migration Guide
+
+### From Manual Provider Registration
+
+**Before (Manual Registration):**
+```go
+// Each instance needs this code
+keycloakProvider := oidc.NewOIDCProvider("keycloak-oidc")
+keycloakProvider.Initialize(keycloakConfig)
+stsService.RegisterProvider(keycloakProvider)
+```
+
+**After (Configuration-Driven):**
+```json
+{
+  "sts": {
+    "providers": [
+      {
+        "name": "keycloak-oidc",
+        "type": "oidc",
+        "enabled": true,
+        "config": {
+          "issuer": "https://keycloak.company.com/realms/seaweedfs",
+          "clientId": "seaweedfs-s3"
+        }
+      }
+    ]
+  }
+}
+```
+
+### Migration Steps
+
+1. **Create Configuration File**: Convert manual provider registrations to JSON config
+2. **Test Single Instance**: Deploy config to one instance and verify functionality
+3. **Validate Consistency**: Ensure all instances load identical providers
+4. **Rolling Deployment**: Update instances one by one with new configuration
+5. **Remove Manual Code**: Clean up manual provider registration code
+
+## Troubleshooting
+
+### Common Issues
+
+#### 1. Provider Inconsistency
+
+**Symptoms**: Authentication works on some instances but not others
+**Diagnosis**: 
+```bash
+# Check provider counts on each instance
+curl http://instance1:8333/sts/providers | jq '.providers | length'
+curl http://instance2:8334/sts/providers | jq '.providers | length'
+```
+**Solution**: Ensure all instances use identical configuration files
+
+#### 2. Token Validation Failures
+
+**Symptoms**: "Invalid signature" or "Invalid issuer" errors
+**Diagnosis**: Check signing key and issuer consistency
+**Solution**: Verify `signingKey` and `issuer` are identical across all instances
+
+#### 3. Provider Loading Failures
+
+**Symptoms**: Providers not loaded at startup
+**Diagnosis**: Check logs for provider initialization errors
+**Solution**: Validate provider configuration against schema
+
+#### 4. OIDC Provider Connectivity
+
+**Symptoms**: "Failed to fetch JWKS" errors
+**Diagnosis**: Test OIDC provider connectivity from all instances
+**Solution**: Check network connectivity, DNS resolution, certificates
+
+### Debug Commands
+
+```bash
+# Test configuration loading
+weed s3 -iam.config=/path/to/config.json -test.config
+
+# Validate JWT tokens
+curl -X POST http://localhost:8333/sts/validate-token \
+  -H "Content-Type: application/json" \
+  -d '{"sessionToken": "eyJ0eXAiOiJKV1QiLCJhbGc..."}'
+
+# List loaded providers
+curl http://localhost:8333/sts/providers
+
+# Check session store
+curl http://localhost:8333/sts/sessions/count
+```
+
+## Performance Considerations
+
+### Token Validation Performance
+
+- **JWT Validation**: ~1-5ms per token validation
+- **JWKS Caching**: Cache JWKS responses to reduce OIDC provider load
+- **Session Lookup**: Filer session lookup adds ~10-20ms latency
+- **Concurrent Requests**: Each instance can handle 1000+ concurrent validations
+
+### Scaling Recommendations
+
+- **Horizontal Scaling**: Add more S3 gateway instances behind load balancer
+- **Session Store Optimization**: Use SSD storage for filer session store
+- **Provider Caching**: Implement JWKS caching to reduce provider load
+- **Connection Pooling**: Use connection pooling for filer communication
+
+## Summary
+
+The configuration-driven provider system solves critical distributed deployment issues:
+
+- ✅ **Automatic Provider Loading**: No manual registration code required
+- ✅ **Configuration Consistency**: All instances load identical providers from config
+- ✅ **Easy Management**: Update config file, restart services
+- ✅ **Production Ready**: Supports OIDC, proper session management, distributed storage
+- ✅ **Backwards Compatible**: Existing manual registration still works
+
+This enables SeaweedFS S3 Gateway to **scale horizontally** with **consistent authentication** across all instances, making it truly **production-ready for enterprise deployments**.

+# S3 Server-Side Encryption (SSE) Integration Tests
+
+This directory contains comprehensive integration tests for SeaweedFS S3 API Server-Side Encryption functionality. These tests validate the complete end-to-end encryption/decryption pipeline from S3 API requests through filer metadata storage.
+
+## Overview
+
+The SSE integration tests cover three main encryption methods:
+
+- **SSE-C (Customer-Provided Keys)**: Client provides encryption keys via request headers
+- **SSE-KMS (Key Management Service)**: Server manages encryption keys through a KMS provider
+- **SSE-S3 (Server-Managed Keys)**: Server automatically manages encryption keys
+
+### 🆕 Real KMS Integration
+
+The tests now include **real KMS integration** with OpenBao, providing:
+- ✅ Actual encryption/decryption operations (not mock keys)
+- ✅ Multiple KMS keys for different security levels
+- ✅ Per-bucket KMS configuration testing
+- ✅ Performance benchmarking with real KMS operations
+
+See [README_KMS.md](README_KMS.md) for detailed KMS integration documentation.
+
+## Why Integration Tests Matter
+
+These integration tests were created to address a **critical gap in test coverage** that previously existed. While the SeaweedFS codebase had comprehensive unit tests for SSE components, it lacked integration tests that validated the complete request flow:
+
+```
+Client Request → S3 API → Filer Storage → Metadata Persistence → Retrieval → Decryption
+```
+
+### The Bug These Tests Would Have Caught
+
+A critical bug was discovered where:
+- ✅ S3 API correctly encrypted data and sent metadata headers to the filer
+- ❌ **Filer did not process SSE metadata headers**, losing all encryption metadata
+- ❌ Objects could be encrypted but **never decrypted** (metadata was lost)
+
+**Unit tests passed** because they tested components in isolation, but the **integration was broken**. These integration tests specifically validate that:
+
+1. Encryption metadata is correctly sent to the filer
+2. Filer properly processes and stores the metadata
+3. Objects can be successfully retrieved and decrypted
+4. Copy operations preserve encryption metadata
+5. Multipart uploads maintain encryption consistency
+
+## Test Structure
+
+### Core Integration Tests
+
+#### Basic Functionality
+- `TestSSECIntegrationBasic` - Basic SSE-C PUT/GET cycle
+- `TestSSEKMSIntegrationBasic` - Basic SSE-KMS PUT/GET cycle
+
+#### Data Size Validation
+- `TestSSECIntegrationVariousDataSizes` - SSE-C with various data sizes (0B to 1MB)
+- `TestSSEKMSIntegrationVariousDataSizes` - SSE-KMS with various data sizes
+
+#### Object Copy Operations
+- `TestSSECObjectCopyIntegration` - SSE-C object copying (key rotation, encryption changes)
+- `TestSSEKMSObjectCopyIntegration` - SSE-KMS object copying
+
+#### Multipart Uploads
+- `TestSSEMultipartUploadIntegration` - SSE multipart uploads for large objects
+
+#### Error Conditions
+- `TestSSEErrorConditions` - Invalid keys, malformed requests, error handling
+
+### Performance Tests
+- `BenchmarkSSECThroughput` - SSE-C performance benchmarking
+- `BenchmarkSSEKMSThroughput` - SSE-KMS performance benchmarking
+
+## Running Tests
+
+### Prerequisites
+
+1. **Build SeaweedFS**: Ensure the `weed` binary is built and available in PATH
+   ```bash
+   cd /path/to/seaweedfs
+   make
+   ```
+
+2. **Dependencies**: Tests use AWS SDK Go v2 and testify - these are handled by Go modules
+
+### Quick Test
+
+Run basic SSE integration tests:
+```bash
+make test-basic
+```
+
+### Comprehensive Testing
+
+Run all SSE integration tests:
+```bash
+make test
+```
+
+### Specific Test Categories
+
+```bash
+make test-ssec      # SSE-C tests only
+make test-ssekms    # SSE-KMS tests only  
+make test-copy      # Copy operation tests
+make test-multipart # Multipart upload tests
+make test-errors    # Error condition tests
+```
+
+### Performance Testing
+
+```bash
+make benchmark      # Performance benchmarks
+make perf          # Various data size performance tests
+```
+
+### KMS Integration Testing
+
+```bash
+make setup-openbao          # Set up OpenBao KMS
+make test-with-kms          # Run all SSE tests with real KMS
+make test-ssekms-integration # Run SSE-KMS with OpenBao only
+make clean-kms             # Clean up KMS environment
+```
+
+### Development Testing
+
+```bash
+make manual-start   # Start SeaweedFS for manual testing
+# ... run manual tests ...
+make manual-stop    # Stop and cleanup
+```
+
+## Test Configuration
+
+### Default Configuration
+
+The tests use these default settings:
+- **S3 Endpoint**: `http://127.0.0.1:8333`
+- **Access Key**: `some_access_key1`
+- **Secret Key**: `some_secret_key1`
+- **Region**: `us-east-1`
+- **Bucket Prefix**: `test-sse-`
+
+### Custom Configuration
+
+Override defaults via environment variables:
+```bash
+S3_PORT=8444 FILER_PORT=8889 make test
+```
+
+### Test Environment
+
+Each test run:
+1. Starts a complete SeaweedFS cluster (master, volume, filer, s3)
+2. Configures KMS support for SSE-KMS tests
+3. Creates temporary buckets with unique names
+4. Runs tests with real HTTP requests
+5. Cleans up all test artifacts
+
+## Test Data Coverage
+
+### Data Sizes Tested
+- **0 bytes**: Empty files (edge case)
+- **1 byte**: Minimal data
+- **16 bytes**: Single AES block
+- **31 bytes**: Just under two blocks
+- **32 bytes**: Exactly two blocks
+- **100 bytes**: Small file
+- **1 KB**: Small text file
+- **8 KB**: Medium file
+- **64 KB**: Large file
+- **1 MB**: Very large file
+
+### Encryption Key Scenarios
+- **SSE-C**: Random 256-bit keys, key rotation, wrong keys
+- **SSE-KMS**: Various key IDs, encryption contexts, bucket keys
+- **Copy Operations**: Same key, different keys, encryption transitions
+
+## Critical Test Scenarios
+
+### Metadata Persistence Validation
+
+The integration tests specifically validate scenarios that would catch metadata storage bugs:
+
+```go
+// 1. Upload with SSE-C
+client.PutObject(..., SSECustomerKey: key)  // ← Metadata sent to filer
+
+// 2. Retrieve with SSE-C  
+client.GetObject(..., SSECustomerKey: key)  // ← Metadata retrieved from filer
+
+// 3. Verify decryption works
+assert.Equal(originalData, decryptedData)    // ← Would fail if metadata lost
+```
+
+### Content-Length Validation
+
+Tests verify that Content-Length headers are correct, which would catch bugs related to IV handling:
+
+```go
+assert.Equal(int64(originalSize), resp.ContentLength)  // ← Would catch IV-in-stream bugs
+```
+
+## Debugging
+
+### View Logs
+```bash
+make debug-logs     # Show recent log entries
+make debug-status   # Show process and port status
+```
+
+### Manual Testing
+```bash
+make manual-start   # Start SeaweedFS
+# Test with S3 clients, curl, etc.
+make manual-stop    # Cleanup
+```
+
+## Integration Test Benefits
+
+These integration tests provide:
+
+1. **End-to-End Validation**: Complete request pipeline testing
+2. **Metadata Persistence**: Validates filer storage/retrieval of encryption metadata
+3. **Real Network Communication**: Uses actual HTTP requests and responses
+4. **Production-Like Environment**: Full SeaweedFS cluster with all components
+5. **Regression Protection**: Prevents critical integration bugs
+6. **Performance Baselines**: Benchmarking for performance monitoring
+
+## Continuous Integration
+
+For CI/CD pipelines, use:
+```bash
+make ci-test        # Quick tests suitable for CI
+make stress         # Stress testing for stability validation
+```
+
+## Key Differences from Unit Tests
+
+| Aspect | Unit Tests | Integration Tests |
+|--------|------------|------------------|
+| **Scope** | Individual functions | Complete request pipeline |
+| **Dependencies** | Mocked/simulated | Real SeaweedFS cluster |
+| **Network** | None | Real HTTP requests |
+| **Storage** | In-memory | Real filer database |
+| **Metadata** | Manual simulation | Actual storage/retrieval |
+| **Speed** | Fast (milliseconds) | Slower (seconds) |
+| **Coverage** | Component logic | System integration |
+
+## Conclusion
+
+These integration tests ensure that SeaweedFS SSE functionality works correctly in production-like environments. They complement the existing unit tests by validating that all components work together properly, providing confidence that encryption/decryption operations will succeed for real users.
+
+**Most importantly**, these tests would have immediately caught the critical filer metadata storage bug that was previously undetected, demonstrating the crucial importance of integration testing for distributed systems.
