TypeError: no salt specified

[berisla...@gmail.com]

Hi, I have just trying out the library, but have ran into a strange problem straight away. I'm just following the steps from the basic tutorial:

>>> from passlib.hash import pbkdf2_sha256
>>> pbkdf2_sha256("aaa")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/berislav/.virtualenvs/toptal/lib/python3.8/site-packages/passlib/utils/handlers.py", line 1795, in __init__
    super(HasRounds, self).__init__(**kwds)
  File "/home/berislav/.virtualenvs/toptal/lib/python3.8/site-packages/passlib/utils/handlers.py", line 1417, in __init__
    raise TypeError("no salt specified")
TypeError: no salt specified

I've tried it in Python versions 3.6, 3.7 and 3.8, in pristine new virtualenvs... Any ideas what am I doing wrong here?

Thank you!

Best,

Berislav

This tutorial: https://passlib.readthedocs.io/en/stable/ ?

Please read this line in the tutorial again. You're missing something essential.
Try to copy paste it from the tutorial first.

I like it that you've tried multiple things to narrow the problem down. Unfortunately it has nothing to do with the python version.

Hi!

You actually want to be using the ".hash()" method of the class, not calling the constructor itself (the tutorial should probably emphasize that).

Try 

   >>> pbkdf2_sha256.hash("aaa")

Instead of

   >>> pbkdf2_sha256("aaa")
