# *argon2-cffi*: Argon2 for Python

[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

```

- The low-level Argon2 CFFI bindings are maintained in the separate [*argon2-cffi-bindings*](https://github.com/hynek/argon2-cffi-bindings) project.

## Release Information

### Removed

- Python 3.6 is not supported anymore.

### Deprecated

- The `InvalidHash` exception is deprecated in favor of `InvalidHashError`.
  No plans for removal currently exist and the names can (but shouldn't) be used interchangeably.

- `argon2.hash_password()`, `argon2.hash_password_raw()`, and `argon2.verify_password()` that have been soft-deprecated since 2016 are now hard-deprecated.
  They now raise `DeprecationWarning`s and will be removed in 2024.

### Added

- Official support for Python 3.11 and 3.12.
  No code changes were necessary.

- `argon2.exceptions.InvalidHashError` as a replacement for `InvalidHash`.

- *salt* parameter to `argon2.PasswordHasher.hash()` to allow for custom salts.
  This is only useful for specialized use-cases -- leave it on None unless you know exactly what you are doing.
