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 <https://github.com/micropython/micropython-lib/tree/master/hashlib>
_
This driver depends on:
Adafruit CircuitPython <https://github.com/adafruit/circuitpython>
_Please ensure all dependencies are available on the CircuitPython filesystem.
This is easily achieved by downloading
the Adafruit library and driver bundle <https://github.com/adafruit/Adafruit_CircuitPython_Bundle>
_.
On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI <https://pypi.org/project/adafruit-circuitpython-hashlib/>
_. To install for current user:
.. code-block:: shell
pip3 install adafruit-circuitpython-hashlib
To install system-wide (this may be required in some cases):
.. code-block:: shell
sudo pip3 install adafruit-circuitpython-hashlib
To install in a virtual environment in your current project:
.. code-block:: shell
mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-hashlib
.. code-block:: python
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))
API documentation for this library can be found on Read the Docs <https://docs.circuitpython.org/projects/hashlib/en/latest/>
