The secure Argon2 password hashing algorithm.
Project description
Argon2 won the Password Hashing Competition and argon2-cffi is the simplest way to use it in Python and PyPy:
>>> 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 hashProject Information
argon2-cffi is available from PyPI, the documentation lives at Read the Docs, the code on GitHub. The low-level Argon2 CFFI bindings are maintained in the separate project argon2-cffi-bindings.
It targets Python 3.6 and newer, and PyPy3. The last version that works with Python 2.7 is 20.1.0, and the last version that works with Python 3.5 is 21.1.0.
argon2-cffi implements Argon2 version 1.3, as described in Argon2: the memory-hard function for password hashing and other applications.
