pyaescbc

Description

AES-CBC encryption tools based on crytography package !

The package pyaescbc provides functions to encrypt and decrypt data using the AES-CBC encryption mode. The package is written in Python and uses the cryptography library for the AES encryption and decryption. The package also provides functions to create an HMAC value from the derived key, IV, and ciphertext. The package is designed to be easy to use.

Security considerations

Usage

General usage of the package includes:

import pyaescbc

# Encryption
cleardata = bytearray("Hello, World!", 'utf-8')
password = bytearray("password", 'utf-8')
iterations = 2_000_000
authdata = bytearray("user=toto", 'utf-8') # Optional authentication data (can be None)
encrypted_bundle = pyaescbc.encrypt(cleardata, password, iterations=iterations, authdata=authdata, delete_keys=True, delete_data=True)

# Decryption
password = bytearray("password", 'utf-8')
authdata = bytearray("user=toto", 'utf-8') # Optional authentication data (can be None)
decrypted_data = pyaescbc.decrypt(encrypted_bundle, password, authdata=authdata, delete_keys=True)

print(decrypted_data)
