Headers-generator is a web-based tool designed to help developers and API users generate secure cryptographic signatures for API requests. It supports multiple hashing algorithms (SHA-1, SHA-256, SHA-512) and provides a modern, interactive interface for generating and copying custom API headers.

• 🔒 Supports SHA-1, SHA-256, SHA-512 algorithms
• 🎨 Modern, animated UI for a smooth user experience
• 📝 Customizable header prefix (Title)
• ⏱️ Timestamp-based signature generation
• 📋 Copy result button for easy integration
• 🌐 Language support for algorithm documentation (English & Japanese)
• 📖 Algorithm introduction page with detailed explanations and comparison

1. Enter your API Key and Secret.
2. Choose a custom header title and select the desired hashing algorithm.
3. Click Generate Signature to create the headers:
   • X-<Title>-Api-Key
   • X-<Title>-Timestamp
   • X-<Title>-Signature
4. Copy the result and use it in your API requests.
