Examples
To create a valid Django hash, using pbkdf2_sha256:
salt = django_salt(12)
opts = [digest: :sha256, format: :django]
Pbkdf2.Base.hash_password(password, salt, opts)
This example uses 160_000 rounds. Add rounds: number
to the opts
if you want to change the number of rounds.

- the default is 160_000
- this can also be set in the config file
:format
- the output format of the hash- the default is modular crypt format
