🧬 GeneCrypt – Genetic obfuscation tool

GeneCrypt is a Python-based CLI tool that encodes and decodes text or files into DNA-style sequences (A, T, G, C) using a custom, reversible transformation pipeline.

It’s a blend of data compression, hashing, and genetic code-inspired encoding — designed to be both secure and fun.

🔐 Security Status

GeneCrypt is currently in early beta.

• ✅ The encoded data is reversible only with the correct numeric key
• 🔓 The encoding method is decodable with effort in its current form
• 🛡️ Future updates will improve security with:
  • Salted and non-deterministic key generation
  • Hybrid encryption support
  • Optional HMAC integrity checks

⚠️ Until then, consider GeneCrypt secure for experimentation, prototyping, and creative applications — but not for storing high-risk sensitive data.

📦 Features

• Convert any text or file to a DNA-style sequence (ATGC)
• Compress and encode input using zlib + base64
• Generate a numeric key using SHA-256 from a derived password
• Reversible decoding with the correct key
• File support for encryption/decryption
• Easy-to-use command line interface

🛠️ Installation

Clone the repository:

git clone https://github.com/your-username/genecrypt.git
cd genecrypt

Run with Python:

python genecrypt.py --help

---

🚀 Usage

🔐 Encrypt Text

python genecrypt.py -m encrypt -t text -i "Hello, World!"

🔐 Encrypt File

python genecrypt.py -m encrypt -t file -i example.txt

🔓 Decrypt Text

python genecrypt.py -m decrypt -t text -i <GENETIC_CODE> -p <NUMERIC_SECRET>

🔓 Decrypt File

python genecrypt.py -m decrypt -t file -i example.txt -p <NUMERIC_SECRET>

🧪 How It Works

1. Compress input with zlib and encode with base64
2. Convert to binary and then into DNA-style bases (A=00, T=01, G=10, C=11)
3. Generate the complement of the sequence
4. Decode complement back to a password
5. Hash and convert password into a numeric key
6. Use key to encode original text into the final genetic string

🔗 Roadmap

• Non-deterministic output with salt
• Optional AES-256 hybrid encryption layer
• Built-in HMAC for integrity verification
• Web-based UI (coming soon!)

💡 Example

Input: "Hello, World!"
➡ Genetic Code: ATGCTAGTC...
➡ Complement: TACGATCAG...
➡ Final DNA Code: TGCAAGT...
➡ Use secret to decode
