adafruit-circuitpython-hashlib

Introduction

This module implements a common interface to many different secure hash and message digest algorithms. Included are the FIPS secure hash algorithms SHA1, SHA224, SHA256, SHA384, and SHA512 (defined in FIPS 180-2) as well as RSA’s MD5 algorithm (defined in Internet RFC 1321).

The SHA1 algorithm is not supported by the CircuitPython module.

This library is based on the work performed in the micropython-lib hashlib module by Paul Sokolovsky

Dependencies

This driver depends on:

Adafruit CircuitPython

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 adafruit-circuitpython-hashlib

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

sudo pip3 install adafruit-circuitpython-hashlib

To install in a virtual environment in your current project:

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

Usage Example

import adafruit_hashlib as hashlib
m = hashlib.sha256()
m.update(b"CircuitPython")
print("Msg Hex Digest: {}\nMsg Digest Size: {}\nMsg Block Size: {}".format(
        m.hexdigest(), m.digest_size, m.block_size))
