:mod:`uhashlib` -- hashing algorithm
|
|
====================================
|
|
|
|
.. module:: uhashlib
|
|
:synopsis: hashing algorithm
|
|
|
|
This module implements binary data hashing algorithms. Currently, it
|
|
implements SHA256 algorithm. Choosing SHA256 was a deliberate choice,
|
|
as a modern, cryptographically secure algorithm. This means that a
|
|
single algorithm can cover both usecases of "any hash algorithm" and
|
|
security-related usage, and thus save space omitting legacy algorithms
|
|
like MD5 or SHA1.
|
|
|
|
Constructors
|
|
------------
|
|
|
|
.. class:: uhashlib.sha256([data])
|
|
|
|
Create a hasher object and optionally feed ``data`` into it.
|
|
|
|
|
|
Methods
|
|
-------
|
|
|
|
.. method:: sha256.update(data)
|
|
|
|
Feed more binary data into hash.
|
|
|
|
.. method:: sha256.digest()
|
|
|
|
Return hash for all data passed thru hash, as a bytes object. After this
|
|
method is called, more data cannot be fed into hash any longer.
|
|
|
|
.. method:: sha256.hexdigest()
|
|
|
|
This method is NOT implemented. Use ``ubinascii.hexlify(sha256.digest())``
|
|
to achieve similar effect.
