Fador's simple crypto library

Fador's crypto library

This project provides a simple implementation of crypto algorithms in C++. Currently only thing supported is AES (Advanced Encryption Standard), specifically focusing on AES-128 in ECB (Electronic Codebook) and CBC (Cipher Block Chaining) modes.

WARNING

This implementation is created for educational purposes and should NOT be used for security-critical applications. This code lacks many features and safeguards that a secure encryption system requires. In a real-world application, always use a well-reviewed cryptographic library that provides these necessary features and has been tested for security vulnerabilities.

Features

• AES-128 encryption/decryption in ECB mode
• AES-128 encryption/decryption in CBC mode
• Key Expansion
• Various helper functions (SubBytes, ShiftRows, MixColumns, AddRoundKey, etc.)

Building and Running the Project

This project is a simple single-file C++ program. To build it, you'll need a C++ compiler that supports at least the C++11 standard.

Here's how to build the project:

g++ -std=c++11 -o aes128 AES128_test.cpp

Then, you can run it like so:

./aes128

This will run the program with a predefined plaintext and key, outputting the original text, the encrypted text, and the decrypted text.

Python

The project includes an experimental python interface, which can be built and tested by going to python/ and running:

python setup.py bdist_wheel
pip install dist/fcryptolib_fador*.whl
python tests/simple_test.py
