🔐 Secure Text Encryption Tool

A modern web application that provides secure text encryption and decryption using the AES-256-GCM algorithm. This tool allows users to safely encrypt sensitive messages and generate secure keys for decryption.

✨ Features

• Strong Encryption: Implements AES-256-GCM encryption for maximum security
• Key Generation: Automatic secure key generation for each encryption
• User-Friendly Interface: Clean and intuitive UI for easy encryption/decryption
• Copy to Clipboard: One-click copying of encrypted text and keys
• Real-Time Feedback: Immediate visual feedback for all operations
• Mobile Responsive: Works seamlessly across all device sizes

🔒 Security Features

• Uses the Web Crypto API for cryptographically secure operations
• Implements AES-256-GCM encryption algorithm
• Generates secure random initialization vectors (IV)
• No data storage - all operations performed client-side
• No external API calls for encryption/decryption

🎯 Use Cases

• Secure message sharing
• Password protection
• Sensitive data encryption
• Secure note-taking

📝 How to Use

1. To Encrypt:

   • Enter your message in the input field
   • Click "Encrypt"
   • Copy both the encrypted text and the key
   • Share them separately with your recipient

2. To Decrypt:

   • Paste the encrypted text
   • Enter the encryption key
   • Click "Decrypt"
   • View your original message

⚠️ Security Best Practices

• Always share the encryption key through a different communication channel than the encrypted message
• Never store encryption keys in plain text
• Use unique keys for different messages
• Clear sensitive data after use
