[Argon2](https://github.com/p-h-c/phc-winner-argon2) won the [Password Hashing Competition](https://www.password-hashing.net/) and *argon2-cffi* is the simplest way to use it in Python:

```pycon

>>> from argon2 import PasswordHasher

>>> ph = PasswordHasher()

>>> hash = ph.hash("correct horse battery staple")

>>> hash  # doctest: +SKIP

'$argon2id$v=19$m=65536,t=3,p=4$MIIRqgvgQbgj220jfp0MPA$YfwJSVjtjSU0zzV/P3S9nnQ/USre2wvJMjfCIjrTQbg'

>>> ph.verify(hash, "correct horse battery staple")

True

>>> ph.check_needs_rehash(hash)

False

>>> ph.verify(hash, "Tr0ub4dor&3")

Traceback (most recent call last):

  ...

argon2.exceptions.VerifyMismatchError: The password does not match the supplied hash

```
