EncFilex (EFX) v1.1

🔒 EncFilex (EFX) is a modern file encryption system with double layers:

1. Base64 Encoding
2. AES-256-GCM
3. XChaCha20-Poly1305

Designed so that any file (text, image, video, document) can be securely encrypted and only opened with the correct password.

✨ Features

• 🔐 AES-256-GCM for symmetric security
• ⚡ XChaCha20-Poly1305 for extra security & long nonce
• 📦 Supports large binary files (image, video, doc, etc.)
• 🛡️ Password-based key derivation using Argon2
• 🎯 Usable via Python API or Command Line (CLI)

📦 Installation

Install from PyPI:

pip install encfilex

🚀 Usage

1. API (in Python)

from EFX import encrypt_file, decrypt_file

# Encrypt
encrypt_file("secret.png", "secret.efx", "super-password")

# Decrypt
decrypt_file("secret.efx", "recovered.png", "super-password")

2. Command Line (CLI)

After installation, the encfilex command is available.

Encrypt file

efx encrypt secret.png secret.efx --password super-password

Decrypt file

efx decrypt secret.efx secret.png --password super-password

⚠️ Notes

• Don't forget to keep your password safe.
• If lost, files cannot be recovered (no backdoor).
• The size of the encrypted file can be about 30% larger than the original (due to metadata + Base64).
• Python 3.9+ is recommended.
