A modern, secure text encryption–decryption desktop app built in Python using:

• AES-256 (GCM mode) for encryption
• PBKDF2-HMAC-SHA512 for key derivation
• HMAC-SHA512 for integrity / tamper protection
• A clean Tkinter + ttk graphical user interface

This project lets you safely encrypt and decrypt any text using strong cryptography with an easy-to-use GUI.

• AES-256 in GCM mode (authenticated encryption)
• PBKDF2-HMAC-SHA512 with 100,000 iterations for key derivation
• Per-message random values:
  • 32-byte salt
  • 16-byte nonce
  • 16-byte IV

• Full message authentication via HMAC-SHA512
• Detects:
  • Incorrect passwords
  • Tampered / corrupted encrypted data

• Built with Tkinter and ttk themed widgets
• Separate sections for:
  • Encryption
  • Decryption
• One-click actions:
  • Encrypt Text
  • Decrypt Text
  • Copy Encrypted
  • Paste to Decrypt
  • Use Default Password
  • Clear All

• Default password: 1234 (for testing only – you should change this)
• Secure clipboard handling for encrypted text
• Clear and friendly dialog messages for success and errors
