+# Hash
+
+A concise and efficient macOS hash calculation tool that supports multiple hash algorithms and batch file processing.
+
+## Features
+
+- 🔐 **Multiple Hash Algorithm Support**: MD5, SHA-1, CRC32
+- 📁 **Batch File Processing**: Calculate hash values for multiple files simultaneously
+- 🎯 **Drag & Drop Operation**: Simply drag files to the application window to start calculation
+- 📋 **One-Click Copy**: Click to copy hash values to clipboard
+- 📊 **File Information Display**: Shows file size, version info, modification date, etc.
+- 🌍 **Multilingual Support**: Supports 22 languages including Chinese, English, Japanese, Korean, German, French, Spanish, Russian, Arabic, etc.
+- 🎨 **Modern Interface**: Native macOS app built with SwiftUI
+- ⚡ **High Performance Computing**: Asynchronous processing with support for large files

+
+## System Requirements
+
+- macOS 11.0 or later
+- Xcode 13.0 or later (for development)
+
+## Installation
+
+### Build from Source
+
+1. Clone the repository:
+```bash
+git clone https://github.com/iOSDevLog/Hash
+cd Hash
+```
+
+2. Open the project with Xcode:
+```bash
+open Hash.xcodeproj
+```
+
+3. Build and run the project in Xcode (⌘+R)
+
+## Usage
+
+### Basic Operations
+
+1. **Launch the Application**: Double-click the app icon or launch from Launchpad
+
+2. **Add Files**:
+   - Click the "Select Files" button to choose files
+   - Or drag files directly to the application window
+
+3. **Select Hash Algorithm**:
+   - Check the desired hash algorithms in the right panel
+   - Supports MD5, SHA-1, CRC32
+
+4. **Start Calculation**:
+   - Click the "Start Calculation" button
+   - Or calculation starts automatically after adding files
+
+5. **Copy Results**:
+   - Click any hash value to copy to clipboard
+   - Supports copying individual hash values or all results
+
+### Advanced Features
+
+- **Batch Processing**: Add multiple files for simultaneous batch calculation
+- **Progress Display**: Real-time calculation progress display
+- **File Management**: Support for clearing individual files or all files
+- **Result Export**: Copy all calculation results
+
+## Technical Architecture
+
+### Core Technologies
+
+- **SwiftUI**: Modern user interface framework
+- **CryptoKit**: Apple's official cryptographic framework for SHA-1 calculation
+- **Foundation**: For MD5 and file operations
+- **UniformTypeIdentifiers**: File type identification
