  -H "X-Total-Size: 1024" \
  -H "X-Signature: $(echo -n '/upload/chunked' | openssl dgst -sha256 -hmac 'your-secret' | cut -d' ' -f2)" \
  http://localhost:8080/upload/chunked
 ```
 ### 3. Run Go Tests
 ```bash
 # Run existing tests
 go test ./test/...
 # Run with verbose output
 go test -v ./test/...
 # Run specific tests
 go test -run TestUpload ./test/
 ```
 ## Docker Build (Alternative)

 ```
 ## Troubleshooting
 ### Build Issues
 #### Missing Dependencies
 ```bash
 # Clean module cache and re-download
 go clean -modcache
 go mod download
 ```
 #### Go Version Issues
 ```bash
 # Check Go version
 go version
 # Update Go if needed (Ubuntu/Debian)
 sudo snap install go --classic
 # Or download from https://golang.org/dl/
 ```
 #### Network Resilience Files Missing
 ```bash
 # Check if files exist
 ls -la cmd/server/upload_session.go
 ls -la cmd/server/network_resilience.go
 ls -la cmd/server/chunked_upload_handler.go
 ls -la cmd/server/integration.go
 # If missing, the build will work but without network resilience features
 # Core functionality remains unchanged
 ```
 ### Runtime Issues
 #### Port Already in Use
 ```bash
 # Check what's using port 8080
 sudo netstat -tlnp | grep :8080
 # Kill process if needed
 sudo kill $(sudo lsof -t -i:8080)
 ```
 #### Permission Issues
 ```bash
 # Make binary executable
 chmod +x hmac-file-server
 # For system service installation
 sudo chown root:root hmac-file-server
 sudo chmod 755 hmac-file-server
 ```
 #### Config File Issues
 ```bash
 # Validate config syntax
 ./hmac-file-server --config config.toml --validate
 # Use example config as starting point
 cp config-example-xmpp.toml config.toml
 ```
 ## Build Performance
 ### Faster Builds
 ```bash
 # Use build cache
 export GOCACHE=$(go env GOCACHE)
 # Parallel builds
 go build -p 4 cmd/server/*.go
 # Skip tests during development
 go build -a cmd/server/*.go
 ```
 ### Smaller Binaries
 ```bash
 # Strip debug info and symbol table
 go build -ldflags="-s -w" cmd/server/*.go
 # Use UPX compression (if installed)
 upx --best hmac-file-server
 ```
 ## Deployment
 ### System Service
 ```bash
 # Copy binary to system location
 sudo cp hmac-file-server /usr/local/bin/
 # Create systemd service
 sudo cp hmac-file-server.service /etc/systemd/system/
 sudo systemctl enable hmac-file-server
 sudo systemctl start hmac-file-server
 ```
 ### Reverse Proxy Setup
 ```bash
 # Nginx configuration
 sudo cp nginx-hmac-file-server.conf /etc/nginx/sites-available/
 sudo ln -s /etc/nginx/sites-available/hmac-file-server.conf /etc/nginx/sites-enabled/
 sudo nginx -t && sudo systemctl reload nginx
 ```
 This build process ensures that:
 - ✅ **Backward Compatibility**: Works with or without network resilience files
 - ✅ **Feature Detection**: Automatically includes available network resilience features  
 - ✅ **Zero Downtime**: Existing deployments continue working unchanged
 - ✅ **Mobile Optimized**: New features specifically address network switching issues

 ## 🎯 **TECHNICAL IMPLEMENTATION**
 ### Core Function: `GetContentType(filename string) string`
 ```go
 // Enhanced MIME type detection with fallback support
 func GetContentType(filename string) string {
    ext := strings.ToLower(filepath.Ext(filename))
    // First try Go's built-in MIME detection  
    if mimeType := mime.TypeByExtension(ext); mimeType != "" {
        return mimeType
    }
    // Try enhanced mappings
    if mimeType, found := enhancedMimeTypes[ext]; found {
        return mimeType
    }
    // Fallback to generic binary type
    return "application/octet-stream"
 }
 ```
 ### Integration Points
 1. **HMAC Authentication** (`validateHMAC`): Uses `GetContentType()` for v2/token protocols

 2. XMPP Server → HTTP Upload Server: Generate slot with HMAC
 3. HTTP Upload Server → Client: PUT URL + HMAC headers
 4. Client → HTTP Upload Server: PUT file with HMAC authentication
 5. HTTP Upload Server: Validates HMAC → 201 Created
 ```
 ### 🔐 HMAC Authentication Flow (IMMUTABLE)
 Our server supports the **standard XEP-0363 authentication methods**:
 #### Method 1: Authorization Header (Most Common)
 ```http
 PUT /upload/file.jpg
 Authorization: Basic base64(hmac_signature)
 Content-Length: 12345
 ```
 #### Method 2: Cookie Header
 ```http
 PUT /upload/file.jpg
 Cookie: auth=hmac_signature
 Content-Length: 12345
 ```
 #### Method 3: Custom Headers (Extended)
 ```http
 PUT /upload/file.jpg
 X-HMAC-Signature: sha256=hmac_value
 X-HMAC-Timestamp: 1234567890
 Content-Length: 12345

 ```go
 // Our server correctly implements these headers for ALL clients
 allowedHeaders := []string{
    "Authorization",  // Most common - HMAC signature
    "Cookie",        // Alternative authentication
    "Expires",       // Upload timeout
 }
 ```
 ### 3. ✅ CORS Configuration (Web Client Support)
 ```toml
 [http]
 cors_enabled = true
 cors_origins = ["*"]
 cors_methods = ["OPTIONS", "HEAD", "GET", "PUT"]
 cors_headers = ["Authorization", "Content-Type", "Content-Length"]

 # HMAC File Server - Podman Configuration Examples
 This directory contains Podman-specific deployment files for HMAC File Server 3.3.0 "Nexus Infinitum".
 ## 🚀 Quick Start
 ```bash
 # Clone repository
 git clone https://git.uuxo.net/uuxo/hmac-file-server.git
 cd hmac-file-server/dockerenv/podman
 # Deploy with single command
 ./deploy-podman.sh
 # Check status
 ./deploy-podman.sh status
 # View logs
 ./deploy-podman.sh logs
 ```
 ## 📁 Files Overview
 ### `Dockerfile.podman`
 - **Purpose**: Optimized Dockerfile for Podman deployment
 - **Features**: 
  - Security-hardened Alpine-based image
  - Non-root user (UID 1011)
  - Health checks included
  - Static binary compilation
  - Minimal attack surface
 ### `deploy-podman.sh`
 - **Purpose**: Complete deployment automation script
 - **Features**:
  - Interactive deployment with colored output
  - Automatic configuration generation with random secrets
  - Security-hardened container settings
  - Pod management for XMPP integration
  - Health monitoring and status reporting
 ### `hmac-file-server.service`
 - **Purpose**: Systemd service unit for service management
 - **Usage**: Place in `~/.config/systemd/user/` (rootless) or `/etc/systemd/system/` (system-wide)
 ## 🛠️ Deployment Commands
 ### Basic Deployment
 ```bash
 # Full deployment (directories, config, build, start)
 ./deploy-podman.sh deploy
 # Start services only
 ./deploy-podman.sh start
 # Stop all services
 ./deploy-podman.sh stop
 # Restart services
 ./deploy-podman.sh restart
 ```
 ### Management Commands
 ```bash
 # Check status and health
 ./deploy-podman.sh status
 # View real-time logs
 ./deploy-podman.sh logs
 # Show current configuration
 ./deploy-podman.sh config
 # Build image only
 ./deploy-podman.sh build
 # Create networking pod only
 ./deploy-podman.sh pod
 # Complete cleanup (keeps data)
 ./deploy-podman.sh clean
 ```
 ## 🔧 Configuration
 ### Environment Variables
 ```bash
 # Custom data directory
 export APP_DATA="/custom/path/hmac-file-server"
 # Custom ports
 export LISTEN_PORT="9999"
 export METRICS_PORT="9998"
 # Deploy with custom settings
 ./deploy-podman.sh
 ```
 ### Generated Configuration
 The deployment script generates a production-ready configuration with:
 - ✅ **XMPP-compatible file extensions**
 - ✅ **Random HMAC and JWT secrets**
 - ✅ **Optimized performance settings**
 - ✅ **Security hardening enabled**
 - ✅ **Comprehensive logging**
 ## 🔒 Security Features
 ### Container Security
 - **Rootless operation**: Runs as non-root user (UID 1011)
 - **Capability dropping**: `--cap-drop=ALL`
 - **No new privileges**: `--security-opt no-new-privileges`
 - **Read-only filesystem**: `--read-only` with tmpfs for /tmp
 - **SELinux labels**: Volume mounts with `:Z` labels
 ### Network Security
 - **Pod isolation**: Containers run in isolated pods
 - **Port binding**: Only necessary ports exposed
 - **Health monitoring**: Built-in health checks
 ## 🔄 Systemd Integration
 ### User Service (Rootless - Recommended)
 ```bash
 # Copy service file
 cp hmac-file-server.service ~/.config/systemd/user/
 # Enable and start
 systemctl --user daemon-reload
 systemctl --user enable hmac-file-server.service
 systemctl --user start hmac-file-server.service
 # Check status
 systemctl --user status hmac-file-server.service
 ```
 ### System Service (Root)
 ```bash
 # Copy service file
 sudo cp hmac-file-server.service /etc/systemd/system/
 # Enable and start
 sudo systemctl daemon-reload
 sudo systemctl enable hmac-file-server.service
 sudo systemctl start hmac-file-server.service
 # Check status
 sudo systemctl status hmac-file-server.service
 ```
 ## 🎯 XMPP Integration
 ### Pod-based XMPP Deployment
 ```bash
 # Create XMPP services pod
 podman pod create --name xmpp-services \
  --publish 5222:5222 \
  --publish 5269:5269 \
  --publish 5443:5443 \
  --publish 8888:8888
 # Add Prosody XMPP server
 podman run -d --pod xmpp-services --name prosody \
  -v ./prosody-config:/etc/prosody:ro \
  -v ./prosody-data:/var/lib/prosody:rw \
  docker.io/prosody/prosody:latest
 # Add HMAC File Server
 podman run -d --pod xmpp-services --name hmac-file-server \
  -v ./config.toml:/app/config.toml:ro \
  -v ./data:/data:rw \
  localhost/hmac-file-server:latest -config /app/config.toml
 ```
 ## 📊 Monitoring and Health
 ### Health Checks
 ```bash
 # Manual health check
 curl -f http://localhost:8888/health
 # Container health status
 podman healthcheck run hmac-file-server
 # Continuous monitoring
 watch -n 5 'curl -s http://localhost:8888/health && echo " - $(date)"'
 ```
 ### Metrics
 ```bash
 # Prometheus metrics
 curl http://localhost:9090/metrics
 # Pod statistics
 podman pod stats xmpp-pod
 # Container logs
 podman logs -f hmac-file-server
 ```
 ## 🚨 Troubleshooting
 ### Common Issues
 #### Permission Errors
 ```bash
 # Fix SELinux contexts
 restorecon -R /opt/podman/hmac-file-server
 # Check volume permissions
 podman unshare ls -la /opt/podman/hmac-file-server
 ```
 #### Container Won't Start
 ```bash
 # Check image exists
 podman images | grep hmac-file-server
 # Validate configuration
 ./deploy-podman.sh config
 # Debug with interactive container
 podman run -it --rm localhost/hmac-file-server:latest /bin/sh
 ```
 #### Network Issues
 ```bash
 # Check pod networking
 podman pod ps
 podman port hmac-file-server
 # Test connectivity
 nc -zv localhost 8888
 ```
 ### Log Analysis
 ```bash
 # Container logs
 podman logs hmac-file-server
 # Application logs
 tail -f /opt/podman/hmac-file-server/logs/hmac-file-server.log
 # System journal
 journalctl --user -u hmac-file-server.service -f
 ```
 ## 🎉 Success Verification
 After deployment, verify everything works:
 1. **Health Check**: `curl -f http://localhost:8888/health`
 2. **Metrics**: `curl http://localhost:9090/metrics`
 3. **Container Status**: `podman ps`
 4. **Pod Status**: `podman pod ps`
 5. **Logs**: `./deploy-podman.sh logs`

 # 🎉 Ejabberd HMAC File Server Integration - COMPLETE!
 ## ✅ What We've Built
 ### 1. **Ejabberd Module** (`mod_http_upload_hmac.erl`)
 - **Full XEP-0363 implementation** with HMAC File Server integration
 - **Automatic Bearer token generation** using XMPP user authentication
 - **Seamless client experience** - zero configuration required
 - **Enterprise features**: user quotas, audit logging, file extension filtering
 ### 2. **Enhanced HMAC File Server** 
 - **Bearer token authentication** added alongside existing HMAC/JWT
 - **User context tracking** for XMPP authentication 
 - **Backward compatibility** maintained for all existing clients
 - **Audit headers** for tracking authentication method
 ### 3. **Complete Installation Ecosystem**
 - **`install.sh`** - Automated installation and configuration
 - **`Makefile`** - Development and maintenance commands
 - **`test.sh`** - Comprehensive integration testing
 - **`README.md`** - Complete documentation and troubleshooting
 ## 🚀 Key Benefits Achieved
 ### For XMPP Users
 - ❌ **NO MORE HMAC CONFIGURATION** in clients!
 - ✅ **Works with ALL XEP-0363 clients** (Conversations, Dino, Gajim, Monal)

 # Ejabberd HMAC File Server Integration Module Proposal
 ## Problem Analysis
 ### Current Issues
 - **Authentication Complexity**: XMPP clients need manual HMAC secret configuration
 - **Re-authentication Failures**: Clients lose connection during network switches  
 - **Secret Management**: Shared secrets must be distributed to all clients
 - **404 Upload Errors**: Direct HTTP upload authentication failures
 - **Configuration Burden**: Each client needs individual HMAC setup
 ## Proposed Solution: `mod_http_upload_hmac`
 ### Architecture Overview
 ```
 XMPP Client → Ejabberd → mod_http_upload_hmac → HMAC File Server
     ↓           ↓              ↓                    ↓
  XEP-0363    Auth Check    Generate Token       Store File
  Request     & Quotas      & Upload URL         & Validate
 ```
 ### Module Features
 #### 1. Seamless Authentication
 ```erlang
 % User authentication via existing XMPP session
 authenticate_user(User, Server) ->
    case ejabberd_auth:check_password(User, Server, undefined) of
        true -> {ok, generate_upload_token(User, Server)};
        false -> {error, unauthorized}
    end.
 ```
 #### 2. Dynamic Token Generation
 ```erlang
 % Generate time-limited upload tokens
 generate_upload_token(User, Filename, Size) ->
    Timestamp = unix_timestamp(),
    Payload = iolist_to_binary([User, $\0, Filename, $\0, integer_to_binary(Size)]),
    Token = crypto:mac(hmac, sha256, get_hmac_secret(), Payload),
    {ok, base64:encode(Token), Timestamp + 3600}. % 1 hour expiry
 ```
 #### 3. XEP-0363 Response Generation
 ```erlang
 % Generate XEP-0363 compliant slot response
 generate_slot_response(User, Filename, Size, ContentType) ->
    {ok, Token, Expiry} = generate_upload_token(User, Filename, Size),
    UUID = uuid:generate(),
    PutURL = iolist_to_binary([get_upload_base_url(), "/", UUID, "/", Filename,
                               "?token=", Token, "&user=", User]),
    GetURL = iolist_to_binary([get_download_base_url(), "/", UUID, "/", Filename]),
    #xmlel{name = <<"slot">>,
           attrs = [{<<"xmlns">>, ?NS_HTTP_UPLOAD}],
           children = [
               #xmlel{name = <<"put">>,
                      attrs = [{<<"url">>, PutURL}],
                      children = [
                          #xmlel{name = <<"header">>,
                                 attrs = [{<<"name">>, <<"Authorization">>}],
                                 children = [{xmlcdata, <<"Bearer ", Token/binary>>}]}
                      ]},
               #xmlel{name = <<"get">>,
                      attrs = [{<<"url">>, GetURL}]}
           ]}.
 ```
 ## Integration Benefits
 ### For XMPP Clients
 - ✅ **Zero Configuration**: No HMAC secrets needed
 - ✅ **Automatic Authentication**: Uses existing XMPP session
 - ✅ **Standard XEP-0363**: Full compliance with all clients
 - ✅ **Error Reduction**: No more 404/authentication failures
 ### For Administrators  
 - ✅ **Centralized Management**: All configuration in ejabberd
 - ✅ **User Quotas**: Per-user upload limits
 - ✅ **Audit Logging**: Complete upload tracking
 - ✅ **Security**: Temporary tokens, no shared secrets
 ### For HMAC File Server
 - ✅ **Token Validation**: Simple Bearer token authentication
 - ✅ **User Context**: Know which XMPP user uploaded files
 - ✅ **Quota Integration**: Enforce limits from ejabberd
 - ✅ **Simplified Auth**: No complex HMAC verification needed
 ## Implementation Plan
 ### Phase 1: Core Module
 ```erlang
 -module(mod_http_upload_hmac).
 -behaviour(gen_mod).
 -export([start/2, stop/1, process_iq/1, mod_options/1]).
 % XEP-0363 IQ handler
 process_iq(#iq{type = get, sub_el = #xmlel{name = <<"request">>}} = IQ) ->
    User = jid:user(IQ#iq.from),
    Server = jid:server(IQ#iq.from),
    % Extract file info from request
    {Filename, Size, ContentType} = extract_file_info(IQ#iq.sub_el),
    % Check quotas and permissions
    case check_upload_permission(User, Server, Size) of
        ok ->
            % Generate upload slot
            SlotResponse = generate_slot_response(User, Filename, Size, ContentType),
            IQ#iq{type = result, sub_el = SlotResponse};
        {error, Reason} ->
            IQ#iq{type = error, sub_el = generate_error(Reason)}
    end.
 ```
 ### Phase 2: HMAC Server Integration
 ```go
 // Enhanced token validation in HMAC File Server
 func validateBearerToken(token, user, filename string, size int64) error {
    // Verify token with ejabberd shared secret
    payload := fmt.Sprintf("%s\x00%s\x00%d", user, filename, size)
    expectedToken := generateHMAC(payload, ejabberdSecret)
    if !hmac.Equal([]byte(token), []byte(expectedToken)) {
        return errors.New("invalid token")
    }
    // Check token expiry and user permissions
    return validateTokenExpiry(token)
 }
 ```
 ### Phase 3: Configuration Integration
 ```yaml
 # ejabberd.yml
 modules:
  mod_http_upload_hmac:
    hmac_server_url: "http://localhost:8080"
    hmac_shared_secret: "your-secure-secret"
    max_size: 104857600  # 100MB
    quota_per_user: 1073741824  # 1GB
    token_expiry: 3600  # 1 hour
    allowed_extensions: [".jpg", ".png", ".pdf", ".mp4"]
 ```
 ## Migration Path
 ### Current Setup → Module Integration
 1. **Install Module**: Deploy `mod_http_upload_hmac` to ejabberd
 2. **Configure Integration**: Set HMAC server URL and shared secret  
 3. **Update HMAC Server**: Add Bearer token authentication support
 4. **Test Integration**: Verify XMPP clients work seamlessly
 5. **Migrate Users**: Remove client-side HMAC configuration
 ### Backward Compatibility
 - ✅ **Dual Authentication**: Support both Bearer tokens and legacy HMAC
 - ✅ **Gradual Migration**: Clients can migrate one by one
 - ✅ **Fallback Support**: Legacy mode for non-integrated setups
 ## Technical Specifications
 ### Token Format
 ```
 Bearer <base64(hmac-sha256(user + filename + size + timestamp, secret))>
 ```
 ### API Enhancement
 ```http
 PUT /upload/uuid/filename.ext?token=bearer_token&user=username
 Authorization: Bearer <token>
 Content-Length: 12345
 [file content]
 ```
 ### Response Format (Success)
 ```http
 HTTP/1.1 201 Created
 Content-Type: application/json
 ```
 ## Development Priority
 ### High Priority Benefits
 1. **Eliminate 404 Errors**: Solves current XMPP client issues
 2. **Simplify Deployment**: No more client-side HMAC configuration
 3. **Enhance Security**: Temporary tokens instead of shared secrets
 4. **Improve UX**: Seamless file uploads for all XMPP clients
 ### Implementation Effort
 - **Ejabberd Module**: ~2-3 days development
 - **HMAC Server Updates**: ~1 day integration

 ## 👤 USER GUIDE
 ### What This Enables
 - **Automatic file uploads** in XMPP clients (Conversations, Dino, Gajim, etc.)
 - **No manual configuration** required in clients
 - **Secure authentication** using your XMPP credentials
 - **Large file support** up to configured limits
 ### Supported XMPP Clients
 ✅ **Conversations** (Android)  
 ✅ **Dino** (Linux/Desktop)  
 ✅ **Gajim** (Cross-platform)  
 ✅ **ChatSecure** (iOS)  
 ✅ **Monal** (iOS/macOS)  
 ✅ **Movim** (Web)  
 ✅ **Any XEP-0363 compatible client**
 ### How to Use
 1. **No setup required** - your XMPP client will automatically discover the upload service
 2. **Send files normally** - use your client's attachment/file sharing feature
 3. **Files upload automatically** - authentication handled transparently
 4. **Recipients get download links** - works across different clients and servers
 ### File Limits (Default Configuration)
 - **Maximum file size**: 100MB per file
 - **Storage quota**: 1GB per user
 - **File retention**: 30 days
 - **Supported types**: Images, videos, audio, documents
 ### Troubleshooting for Users
 **Problem**: File uploads fail  
 **Solution**: Check with your server administrator - the service may be temporarily unavailable
 **Problem**: Files too large  
 **Solution**: Compress files or ask administrator about size limits
 **Problem**: Client doesn't show upload option  
 **Solution**: Ensure your client supports XEP-0363 HTTP File Upload

 SECRET="YOUR-SECURE-SECRET-HERE"
 # Test upload endpoint
 curl -X POST "http://localhost:8080/upload/test-uuid/test.txt" \
     -H "Authorization: Bearer $(echo -n "$USER\0$FILENAME\0$(date +%s)" | openssl dgst -sha256 -hmac "$SECRET" -binary | base64)" \
     -H "Content-Type: text/plain" \
     -d "Test upload content"
 ```
 ---
 ## 🔒 SECURITY CONSIDERATIONS
 ### For Administrators
 - **Use strong shared secrets** (minimum 32 characters)
 - **Enable HTTPS** for production deployments  
 - **Configure appropriate file size limits**
 - **Set up log monitoring** for upload activities
 - **Regular security updates** for both ejabberd and HMAC server
 - **Network isolation** - HMAC server doesn't need internet access
 ### Network Security
 ```bash
 # Firewall configuration example
 sudo ufw allow from [ejabberd-ip] to any port 8080  # HMAC server
 sudo ufw allow 5222/tcp  # XMPP client connections
 sudo ufw allow 5269/tcp  # XMPP server-to-server
 sudo ufw allow 443/tcp   # HTTPS file uploads (if using reverse proxy)
 ```
 ---
 ## 📊 MONITORING AND MAINTENANCE
 ### Log Monitoring
 ```bash
 # HMAC server logs
 sudo tail -f /var/log/hmac-file-server.log
 # ejabberd logs  
 sudo tail -f /var/log/ejabberd/ejabberd.log
 # nginx logs (if using reverse proxy)
 sudo tail -f /var/log/nginx/access.log
 ```
 ### Performance Monitoring
 - Monitor disk usage in upload directory
 - Check memory usage of HMAC server process
 - Monitor ejabberd performance impact
 - Track upload/download statistics
 ### Backup Recommendations
 - **Configuration files**: `/etc/ejabberd/`, `/etc/hmac-file-server/`
 - **Upload data**: `/var/lib/hmac-uploads/` (optional, based on retention policy)
 - **ejabberd database**: Standard ejabberd backup procedures
 ---

 # Ejabberd HMAC File Server Integration Module
 This directory contains `mod_http_upload_hmac`, an ejabberd module that provides seamless integration between XMPP clients and the HMAC File Server, implementing XEP-0363 HTTP File Upload with automatic authentication.
 ## 🎯 Problem Solved
 **Before**: XMPP clients needed manual HMAC secret configuration, suffered from re-authentication failures, and experienced 404 upload errors.
 **After**: Zero client configuration, automatic authentication via existing XMPP session, and seamless file uploads for all XEP-0363 compatible clients.
 ## ✨ Features
 - 🔐 **Seamless Authentication** - Uses existing XMPP user session
 - 🎫 **Bearer Token Generation** - Temporary, secure upload tokens
 - 📱 **Universal Client Support** - Works with Conversations, Dino, Gajim, Monal
 - 👥 **User Management** - Per-user quotas and permissions
 - 📊 **Audit Logging** - Complete upload tracking
 - 🔒 **Enhanced Security** - No shared secrets in clients
 - ⚡ **XEP-0363 Compliant** - Standard HTTP File Upload protocol
 ## 🏗️ Architecture
 ```
 XMPP Client → Ejabberd → mod_http_upload_hmac → HMAC File Server
     ↓           ↓              ↓                    ↓
  XEP-0363    Auth Check    Generate Token       Store File
  Request     & Quotas      & Upload URL         & Validate
 ```
 ## 📦 Installation
 ### Quick Install
 ```bash
 cd ejabberd-module
 sudo ./install.sh
 ```
 ### Manual Installation
 1. **Compile the module:**
 ```bash
 erlc -I /opt/ejabberd/lib/ejabberd-*/include -o . mod_http_upload_hmac.erl
 ```
 2. **Install to ejabberd:**
 ```bash
 sudo cp mod_http_upload_hmac.beam /opt/ejabberd/lib/ejabberd-*/ebin/
 sudo chown ejabberd:ejabberd /opt/ejabberd/lib/ejabberd-*/ebin/mod_http_upload_hmac.beam
 ```
 3. **Configure ejabberd.yml:**
 ```yaml
 modules:
  mod_http_upload_hmac:
    hmac_server_url: "http://localhost:8080"
    hmac_shared_secret: "your-secure-secret"
    max_size: 104857600  # 100MB
    quota_per_user: 1073741824  # 1GB  
    token_expiry: 3600  # 1 hour
    allowed_extensions: 
      - ".jpg"
      - ".png"
      - ".pdf"
      - ".mp4"
      - ".mp3"
    iqdisc: one_queue
 # Disable default mod_http_upload
 # mod_http_upload: []
 ```
 4. **Update HMAC File Server:**
 ```toml
 [ejabberd_integration]
 enabled = true
 bearer_token_auth = true
 shared_secret = "your-secure-secret"  # Same as ejabberd
 ```
 5. **Restart services:**
 ```bash
 sudo systemctl restart ejabberd
 sudo systemctl restart hmac-file-server
 ```
 ## 🔧 Configuration Options
 | Option | Type | Default | Description |
 |--------|------|---------|-------------|
 | `hmac_server_url` | string | `"http://localhost:8080"` | HMAC File Server base URL |
 | `hmac_shared_secret` | string | `"default-secret-change-me"` | Shared secret for token generation |
 | `max_size` | integer | `104857600` | Maximum file size in bytes (100MB) |
 | `quota_per_user` | integer | `1073741824` | User storage quota in bytes (1GB) |
 | `token_expiry` | integer | `3600` | Token validity in seconds (1 hour) |
 | `allowed_extensions` | list | `[]` | Allowed file extensions (empty = all) |
 | `iqdisc` | atom | `one_queue` | IQ processing discipline |
 ## 🚀 Usage
 ### For XMPP Clients
 **No configuration required!** Just use your XMPP client as normal:
 1. Open any XEP-0363 compatible client (Conversations, Dino, Gajim)
 2. Send a file in any chat
 3. File uploads automatically using your XMPP credentials
 4. No HMAC secrets or special configuration needed
 ### For Administrators
 Monitor uploads and manage users:
 ```bash
 # Check ejabberd logs
 journalctl -u ejabberd -f
 # Check HMAC server logs  
 journalctl -u hmac-file-server -f
 # View user quotas (if implemented)
 ejabberdctl get_user_quota username@domain.tld
 ```
 ## 🔐 Security
 ### Authentication Flow
 1. **XMPP Client** requests upload slot via XEP-0363
 2. **Ejabberd** validates user via existing XMPP session
 3. **Module** generates time-limited Bearer token with HMAC
 4. **Client** uploads file with Bearer token to HMAC server
 5. **HMAC Server** validates token and stores file
 ### Token Format
 ```
 Bearer <base64(hmac-sha256(user + filename + size + timestamp, secret))>
 ```
 ### Security Benefits
 - ✅ **No shared secrets** in XMPP clients
 - ✅ **Time-limited tokens** (default 1 hour)
 - ✅ **User-based authentication** via XMPP session
 - ✅ **Per-user quotas** and permissions
 - ✅ **Audit trail** for all uploads
 ## 🧪 Testing
 ### Test Installation
 ```bash
 # Check module loading
 sudo ejabberdctl module_check mod_http_upload_hmac
 # Test with XMPP client
 # 1. Connect to your ejabberd server
 # 2. Try uploading a file
 # 3. Check logs for Bearer token authentication
 ```
 ### Debug Mode
 ```yaml
 # In ejabberd.yml
 log_level: debug
 # Check detailed logs
 journalctl -u ejabberd -f | grep "mod_http_upload_hmac"
 ```
 ## 📱 Client Compatibility
 | Client | Platform | Status | Notes |
 |--------|----------|--------|-------|
 | **Conversations** | Android | ✅ Full Support | Native XEP-0363 |

 ## 🔄 Migration from Manual HMAC
 ### Gradual Migration
 1. **Install module** alongside existing setup
 2. **Test with one client** to verify functionality  
 3. **Remove HMAC config** from clients one by one
 4. **Monitor logs** to ensure all clients switch over
 5. **Disable legacy HMAC** when all clients migrated
 ### Backward Compatibility
 The HMAC File Server supports both authentication methods simultaneously:
 - ✅ **Bearer tokens** (ejabberd module)
 - ✅ **Legacy HMAC** (manual client configuration)
 - ✅ **JWT tokens** (if enabled)
 ## 🐛 Troubleshooting
 ### Common Issues
 **"Module compilation failed"**
 ```bash
 # Install Erlang development tools
 sudo apt-get install erlang-dev erlang-tools
 ```
 **"Authentication failed"**
 ```bash
 # Check shared secret matches
 grep "hmac_shared_secret" /opt/ejabberd/conf/ejabberd.yml
 grep "shared_secret" /etc/hmac-file-server/config.toml
 ```
 **"404 Upload errors"**
 ```bash
 # Verify HMAC server is running
 systemctl status hmac-file-server
 # Check URLs are correct
 curl -I http://localhost:8080/health
 ```
 ### Debug Steps
 1. **Check module loading:**
 ```bash
 sudo ejabberdctl modules | grep http_upload
 ```
 2. **Verify configuration:**
 ```bash
 sudo ejabberdctl get_option modules
 ```
 3. **Test token generation:**
 ```bash
 # Enable debug logging in ejabberd.yml
 log_level: debug
 ```
 4. **Monitor both services:**
 ```bash
 # Terminal 1
 journalctl -u ejabberd -f
 # Terminal 2  
 journalctl -u hmac-file-server -f
 ```

 # HMAC File Server 3.2.2 Test Suite
 This directory contains comprehensive testing tools for the HMAC File Server 3.3.0 "Nexus Infinitum".
 ## 🚀 Quick Start
 Run the complete test suite:
 ```bash
 ./comprehensive_test_suite.sh
 ```
 ## 📋 Test Coverage
 The comprehensive test suite covers:
 ### ✅ Core Functionality
 - **HMAC Validation**: Ensures proper authentication
 - **File Extensions**: Tests allowed/blocked file types
 - **Upload Mechanics**: Validates upload process
 - **Server Health**: Checks service availability
 ### 🎥 XMPP Integration
 - **MP4 Upload**: Tests video file sharing for XMPP clients
 - **Image Upload**: Tests image sharing (PNG, JPEG)
 - **File Size Limits**: Validates large file handling
 ### 🌐 Network Resilience (3.2.2 Features)
 - **Health Monitoring**: Tests network resilience endpoints
 - **Metrics Collection**: Validates monitoring capabilities
 - **Mobile Switching**: Supports seamless network transitions
 ### 🚫 Security Testing
 - **Invalid HMAC**: Ensures rejected authentication fails
 - **Unsupported Extensions**: Confirms blocked file types
 - **Path Validation**: Tests file path sanitization
 ## 🔧 Commands
 ```bash
 # Run all tests
 ./comprehensive_test_suite.sh
 # Setup test files only
 ./comprehensive_test_suite.sh setup
 # Clean up test files
 ./comprehensive_test_suite.sh clean
 # Show help
 ./comprehensive_test_suite.sh help
 ```
 ## 📊 Test Results
 Tests generate detailed logs with:
 - ✅ **Pass/Fail status** for each test
 - 🕒 **Timestamps** for performance tracking
 - 📝 **Detailed output** saved to `/tmp/hmac_test_results_*.log`
 - 📈 **Summary statistics** (passed/failed counts)
 ## 🎯 Expected Results
 When all systems are working correctly:
 - **✅ PASS**: HMAC validation
 - **✅ PASS**: MP4 upload (XMPP)
 - **✅ PASS**: Image upload  
 - **✅ PASS**: Large file upload
 - **✅ PASS**: Server health check
 - **❌ FAIL**: Invalid HMAC (should fail)
 - **❌ FAIL**: Unsupported extension (should fail)
 ## 🔍 Troubleshooting
 ### Common Issues
 1. **Connection refused**: Check if server is running
 2. **403 Forbidden**: Verify HMAC key configuration
 3. **400 Bad Request**: Check file extension configuration
 4. **Timeout**: Large files may need adjusted timeouts
 ### Debug Mode
 For detailed debugging, check server logs:
 ```bash
 sudo journalctl -u hmac-file-server -f
 ```
 ## 📁 File Cleanup
 The test suite automatically cleans up temporary files, but if needed:
 ```bash
 rm -f /tmp/test_*.{txt,mp4,bin,png,xyz}
 rm -f /tmp/hmac_test_results_*.log
 ```
 ## 🔧 Configuration
 Tests use these defaults (modify in script if needed):
 - **Base URL**: `https://xmpp.uuxo.net`
 - **Test User**: `c184288b79f8b7a6f7d87ac7f1fb1ce6dcf49a80`
 - **HMAC Key**: Configured in script
 ## 📝 Legacy Test Files
 This comprehensive suite replaces these scattered root-level test files:
 - `test-hmac-fixed.sh` → Integrated into comprehensive suite
 - `test-upload.sh` → Covered by upload tests
 - `debug-uploads.sh` → Debug logging integrated
 - `comprehensive_upload_test.sh` → Replaced by this suite
 - Various monitor scripts → Health checks integrated
 ## 🎉 3.3.0 "Nexus Infinitum" Features Tested
 - ✅ **Enhanced Network Resilience**: 1-second detection
 - ✅ **Mobile Network Switching**: WLAN ↔ IPv6 5G seamless transitions
 - ✅ **XMPP File Sharing**: Conversations/Gajim compatibility
 - ✅ **Configuration Validation**: Proper extension loading
 - ✅ **Production Deployment**: SystemD, Docker, Podman support
