Documentation License: MIT CII Best Practices PyPI version Downloads / Month

Argon2 won the Password Hashing Competition and argon2-cffi is the simplest way to use it in Python:

>>> 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
