fibcrypt 0.1.5

A fast Fibonacci-based cryptographic toolkit

fibcrypt

fibcrypt is a lightweight, open-source cryptographic toolkit based on fast Fibonacci number generation using matrix exponentiation.

🔐 Features

• Fast Fibonacci-based PRNG (O(log n))
• AES-256 encryption & decryption (CBC mode)
• Custom key derivation function (KDF)
• Modular, pluggable and extensible structure
• Built-in performance profiling

📦 Installation

pip install fibcrypt

🚀 Example Usage

from fibcrypt.crypto_utils import encrypt, decrypt

msg = "This is a secret message"
password = "myStrongPassword123"
salt = "[e-mail]"

# Encrypt
cipher = encrypt(msg, password, salt)
print("Encrypted:", cipher.hex())

# Decrypt
plain = decrypt(cipher, password, salt)
print("Decrypted:", plain)
