Hashing algorithms.

MicroPython module: https://docs.micropython.org/en/v1.21.0/library/hashlib.html
|

CPython module: :mod:`python:hashlib` https://docs.python.org/3/library/hashlib.html .
|
|
|
|
This module implements binary data hashing algorithms. The exact inventory
|
|
of available algorithms depends on a board. Among the algorithms which may
|
|
be implemented:
|
|
|
|
* SHA256 - The current generation, modern hashing algorithm (of SHA2 series).
|
|
It is suitable for cryptographically-secure purposes. Included in the
|
|
MicroPython core and any board is recommended to provide this, unless
|
|
it has particular code size constraints.
|
|
|
|
* SHA1 - A previous generation algorithm. Not recommended for new usages,
|
|
but SHA1 is a part of number of Internet standards and existing
|
|
applications, so boards targeting network connectivity and
|
|
interoperability will try to provide this.
|
|
|
|
* MD5 - A legacy algorithm, not considered cryptographically secure. Only
|
|
selected boards, targeting interoperability with legacy applications,
|
|
will offer this.
