Features

✔ Simple API for encryption and decryption
✔ Uses ChaCha20 for fast, secure encryption
✔ Automatic nonce handling (prepended to ciphertext)
✔ Requires a 32-byte key for security

---

Installation

Install the package using pip:

pip install chacha20-utils

---

Usage

from chacha20_utils import ChaCha20Cipher

# Use a 32-byte secret key
key = b'your_32_byte_secret_key_________________'

cipher = ChaCha20Cipher(key)

# Encrypt
plaintext = b"Hello, ChaCha20!"
encrypted = cipher.encrypt(plaintext)
print("Encrypted:", encrypted)

# Decrypt
decrypted = cipher.decrypt(encrypted)
print("Decrypted:", decrypted)

Notes

• The key must be exactly 32 bytes (256 bits).
• The nonce is randomly generated and prepended to the ciphertext for decryption.
