Introduction

HMAC (Keyed-Hashing for Message Authentication) Python module. Implements the HMAC algorithm as described by RFC 2104.

Dependencies

This driver depends on:

• Adafruit CircuitPython

• Adafruit CircuitPython Hashlib

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install circuitpython-hmac

To install system-wide (this may be required in some cases):

sudo pip3 install circuitpython-hmac

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install circuitpython-hmac

Usage Example

Create a keyed hash for authenticating a message.

secret = "secret"
msg = "message"

key = hmac.new(secret, msg=msg, digestmod=hashlib.sha256).digest()
