+# 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
+
+## 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
+```
+
+### 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.
