Elyx - Secure Terminal Encryption Tool

A secure, user-friendly terminal-based encryption/decryption tool that uses industry-standard AES encryption to protect your sensitive text data.

Features

• Strong Encryption: Uses AES encryption with PBKDF2 key derivation (100,000 iterations)
• Password Generation: Built-in secure password generator (10 characters with mixed case, numbers, and symbols)
• Beautiful Terminal UI: Rich formatting with colors and panels for excellent user experience
• Easy to Use: Simple menu-driven interface
• Secure: Passwords are never stored, all operations happen locally
• Cross-Platform: Works on Windows, macOS, and Linux

pip install -e .

Usage

Run the application:

elyx

Or if installed from source:

python -m elyx.main

Main Menu Options

1. Encrypt Text: Encrypt any text with a password
2. Decrypt Text: Decrypt previously encrypted text
3. Generate Secure Password: Create a random 10-character password
4. Help: View usage instructions
5. Exit: Close the application

Encrypting Text

1. Select option 1 from the main menu
2. Enter or paste the text you want to encrypt
3. Choose to either:
   • Generate a secure password (recommended)
   • Enter your own password (minimum 8 characters)

Decrypting Text

1. Select option 2 from the main menu
2. Paste the encrypted text
3. Enter the password used for encryption
4. Your original text will be displayed

Security Notes

• Uses cryptography library's Fernet implementation (AES 128-bit encryption)
• Passwords are derived using PBKDF2-HMAC-SHA256 with 100,000 iterations
• Each encryption uses a unique random salt
• Encrypted output is Base64 encoded for easy sharing
• All operations happen locally - no data is sent over the network

Requirements

• Python 3.8 or higher
• Dependencies:
  • cryptography >= 41.0.0
  • rich >= 13.7.0
  • click >= 8.1.0
