Features + +- **API Key Authentication**: Authenticate using API keys instead of passwords +- **Permission Scoping**: Separate read and write permissions (sftp:read, sftp:write) +- **User Isolation**: Each user has their own isolated directory (organized by org/user) +- **Audit Logging**: All operations are logged to the audit service +- **Secure by Design**: No symlinks, path traversal protection, permission enforcement + +## Configuration + +Environment variables: + +- `SFTP_PORT`: SFTP server port (default: 2222) +- `SFTP_BASE_PATH`: Base directory for SFTP files (default: /var/lib/sftp) +- `SFTP_HOST_KEY_PATH`: Path to SSH host key (default: /var/lib/sftp/host_key) +- `PORT`: HTTP health check port (default: 3020) +- `DATABASE_URL`: PostgreSQL database URL +- `METRICS_DATABASE_URL`: TimescaleDB URL for audit logs +- `LOG_LEVEL`: Logging level (debug, info, warn, error) + +## API Key Scopes + +API keys must have one or more of these scopes: + +- `sftp:read` - Allow reading/downloading files and listing directories +- `sftp:write` - Allow uploading, deleting, and modifying files +- `sftp:*` or `sftp` - Grant both read and write permissions + +## Usage + +### Creating an API Key + +API keys must be created through the auth service or admin interface with the appropriate SFTP scopes. + +Example: +``` +Scopes: sftp:read,sftp:write +``` + +### Connecting via SFTP + +```bash +# Using command-line SFTP client +sftp -P 2222 -o User=any_username -o IdentityFile=/path/to/key user@hostname + +# When prompted for password, enter your API key + +# Using FileZilla or other GUI clients +Host: sftp://hostname +Port: 2222 +User: any_username (username doesn't matter, authentication is via API key) +Password: your-api-key +``` + +### Directory Structure + +Files are organized by organization and user: + +``` +/var/lib/sftp/ + ├── org-123/ + │ ├── user-456/ + │ │ ├── file1.txt + │ │ └── subdir/ + │ └── user-789/ + │ └── file2.txt + └── org-abc/ + └── user-def/ + └── file3.txt +``` + +Each user can only access their own directory within their organization. + +## Operations + +All operations are audited and logged: + +- **upload**: Upload a file +- **download**: Download a file +- **delete**: Delete a file or directory +- **mkdir**: Create a directory +- **rename**: Rename/move a file +- **list**: List directory contents +- **stat**: Get file information + +## Security + +- **Path Traversal Protection**: Users cannot escape their directory +- **No Symlinks**: Symlink creation and reading is disabled +- **Permission Enforcement**: Operations are checked against API key scopes +- **Audit Trail**: All operations are logged with user, org, and result +- **API Key Tracking**: Last used timestamp is updated on each connection + +## Health Check + +HTTP endpoint available at `http://localhost:3020/health` + +Returns: +```json +{ + "status": "healthy", + "service": "sftp-service", + "timestamp": "2024-01-17T20:00:00Z", + "details": { + "sftp_address": "0.0.0.0:2222", + "base_path": "/var/lib/sftp" + } +} +``` + +## Development + +```bash +# Build +go build -o sftp-service + +# Run +./sftp-service + +# Test connection +sftp -P 2222 test@localhost +# Enter your API key when prompted for password +``` + +## Architecture + +The service consists of three main components: + +1. **SFTP Server** (`pkg/sftp/server.go`): Handles SSH/SFTP protocol +2. **Auth Validator** (`internal/service/auth.go`): Validates API keys against database +3. **Audit Logger** (`internal/service/auth.go`): Logs operations to TimescaleDB + +The server uses the standard Go SSH and SFTP libraries with custom handlers for permission checking and audit logging. diff --git a/apps/sftp-service/go.mod b/apps/sftp-service/go.mod new file mode

Security +- **API Key Authentication**: No password-based auth; all authentication via API keys +- **SHA-256 Hashing**: API keys are hashed before storage and comparison +- **Scoped Permissions**: Granular control with `sftp:read`, `sftp:write`, `sftp:*`, and `sftp` scopes +- **Organization Isolation**: Files organized by org/user, preventing cross-org access +- **Path Traversal Protection**: All paths validated to stay within user's directory +- **No Symlinks**: Symlink operations disabled for security + +### 2. Architecture +- **Microservice Pattern**: Follows existing patterns (audit-service, auth-service, etc.) +- **Graceful Shutdown**: Proper cleanup of SFTP and HTTP servers +- **Health Checks**: HTTP endpoint on port 3020 for monitoring +- **Database Integration**: PostgreSQL for API key storage +- **Audit Logging**: TimescaleDB for operation logs + +### 3.
