micropython-aes

micropython-aes provides a pure Python implementation of the Advanced Encryption Standard (AES) algorithm, specifically adapted for MicroPython. This library enables encryption and decryption capabilities on MicroPython platforms that lack native AES support, making it essential for secure data handling in embedded systems.

Key Features

• Pure Python Implementation — No external C dependencies, ensuring compatibility with MicroPython's constrained environment.
• CBC Mode Support — Implements Cipher Block Chaining (CBC) mode for secure encryption of data streams.
• MicroPython Optimized — Modified from the pyAES project to run efficiently on MicroPython devices like NodeMCU.
• Base64 Integration — Works seamlessly with MicroPython's ubinascii module for encoding and decoding ciphertext.

Philosophy

The project focuses on providing a lightweight, dependency-free cryptographic solution that adheres to the AES standard while being practical for resource-constrained MicroPython deployments.
