Encryptools

Encryptools is a Python package that provides tools for encrypting and decrypting files using a combination of AES and RSA encryption. This package is designed to simplify the process of securing sensitive data.

Features

• Generate RSA key pairs
• Encrypt files using AES symmetric encryption
• Encrypt AES keys with RSA for secure key transmission
• Create decryption scripts to easily decrypt the files

Installation

Encryptools can be installed from PyPI using pip:

pip install encryptools

## Usage

### Generating RSA Keys

You can generate RSA key pairs using the `RSAKeyManager` class:

```python
from encryptools import RSAKeyManager

rsa_manager = RSAKeyManager()
private_key, public_key = rsa_manager.generate_rsa_keys()

# Save keys to files
rsa_manager.save_rsa_key(private_key, public_key, "private_key.pem", "public_key.pem")

Encrypting Data

Encrypt data using the HybridEncryptor class, which combines AES and RSA encryption:

from encryptools import HybridEncryptor

hybrid_encryptor = HybridEncryptor()
data = b"Hello, World!"

# Load public key
with open("public_key.pem", "rb") as f:
    public_key = f.read()

encrypted_symmetric_key, iv, ct_bytes = hybrid_encryptor.hybrid_encrypt(data, public_key)

print("Encrypted symmetric key:", encrypted_symmetric_key)
print("IV:", iv)
print("Ciphertext:", ct_bytes)

Decrypting Data

Decrypt data using the HybridEncryptor class:

# Load private key
with open("private_key.pem", "rb") as f:
    private_key = f.read()

decrypted_data = hybrid_encryptor.hybrid_decrypt(encrypted_symmetric_key, iv, ct_bytes, private_key)

print("Decrypted data:", decrypted_data)

Creating Decryption Scripts

Create a decryption script that can be used to decrypt the file later:

from encryptools import DecryptFileCreator

decrypt_file_creator = DecryptFileCreator(symmetric_key)
decrypt_file_creator.write_decrypt_function_to_file("decrypt_script.py", "encrypted_file.bin", "decrypted_file.txt")

Running Tests

To run the tests, use the following command:

python -m unittest discover -s tests
