  • Videos: .mp4, .mov, .avi, .mkv, .webm, .flv, .wmv
  • Audio: .mp3, .wav, .flac, .aac, .ogg, .m4a, .wma

• Security Features

  • Auto-delete original files after encryption
  • Auto-delete encrypted files after decryption
  • Timestamp tracking for all operations
  • Integrity verification with HMAC and CRC32
  • Password-based encryption with key stretching

Installation

As a Standalone Script

# Make executable
chmod +x quantum_hydra.py

# Run directly
python quantum_hydra.py

As a Python Package

# Install in development mode
pip install -e .

# Or install normally
pip install .

# Or install from PyPI (once published)
pip install quantum-hydra-cipher

Command Aliases

After installation, you can run the cipher using either command:

quantum-hydra    # Full command
qhc              # Short alias (Quantum Hydra Cipher)

Usage

Interactive Mode

python quantum_hydra.py

Follow the on-screen prompts to:

1. Choose encryption or decryption
2. Specify the directory containing your files
3. Enter your master password
4. Confirm the operation

Programmatic Usage

from quantum_hydra import QuantumHydraCipherV3

# Initialize cipher with password
cipher = QuantumHydraCipherV3("your-secure-password")

# Encrypt text
plaintext = "Secret message"
encrypted, salt = cipher.encrypt_text(plaintext, "message.txt")

# Encrypt binary file
with open("image.jpg", "rb") as f:
    data = f.read()
encrypted, salt = cipher.encrypt_binary(data, "image.jpg")

# Decrypt
success, result = cipher.decrypt_data(encrypted, salt, is_binary=True)

File Format

Encrypted files are saved with the .qhc extension (Quantum Hydra Cipher). These files contain:

• Original filename
• File type information
• Encryption timestamp
• Encrypted data
• Salt for key derivation
• Integrity checksums

Security Warnings

⚠️ IMPORTANT:

• Original files are PERMANENTLY DELETED after encryption
• Encrypted files are PERMANENTLY DELETED after decryption
• REMEMBER YOUR PASSWORD - there is no recovery method
• Use strong, unique passwords for maximum security
• Keep backups of important files before encryption

Example Workflow

Encrypting Files

1. Place your files in a directory
2. Run the program and select "ENCODE"
3. Enter the directory path
4. Set a strong password
5. Original files are encrypted to .qhc format and deleted

Decrypting Files

1. Place .qhc files in a directory
2. Run the program and select "DECODE"
3. Enter the directory path
4. Enter the same password used for encryption
5. Files are restored to original format and .qhc files are deleted

Technical Details

Encryption Process (Text Files)

1. Derive 64-byte key from password using PBKDF2-HMAC-SHA512
2. Apply polyalphabetic substitution using 52 shuffled alphabets
3. Compress using zlib (level 9)
4. Apply prime-based columnar transposition
5. XOR with SHA-512 keystream
6. Byte substitution using password-seeded S-Box
7. 8-round Feistel network shuffle
8. Add HMAC-SHA256 and CRC32 for integrity

Encryption Process (Binary Files)

Same as text files, but skips step 2 (polyalphabetic substitution) as it only applies to text.

Requirements

• Python 3.7 or higher
• No external dependencies (uses only standard library)
