# Low-level Python CFFI Bindings for Argon2
*argon2-cffi-bindings* provides low-level [*CFFI*](https://cffi.readthedocs.io/) bindings to the [*Argon2*] password hashing algorithm including a vendored version of them.
<!-- [[[cog
# Extract commit ID; refresh using `tox -e cog`
import subprocess
out = subprocess.check_output(["git", "submodule"], text=True)
id = out.strip().split(" ", 1)[0]
link = f'[**`{id[:7]}`**](https://github.com/P-H-C/phc-winner-argon2/commit/{id})'
print(f"The currently vendored *Argon2* commit ID is {link}.")
]]] -->
The currently vendored *Argon2* commit ID is [**`f57e61e`**](https://github.com/P-H-C/phc-winner-argon2/commit/f57e61e19229e23c4445b85494dbf7c07de721cb).

> If you want to hash passwords in an application, this package is **not** for you.
> Have a look at [*argon2-cffi*] with its high-level abstractions!
These bindings have been extracted from [*argon2-cffi*] and it remains its main consumer.
However, they may be used by other packages that want to use the *Argon2* library without dealing with C-related complexities.
## Usage
*argon2-cffi-bindings* is available from [PyPI](https://pypi.org/project/argon2-cffi-bindings/).
The provided *CFFI* bindings are compiled in API mode.
Best effort is given to provide binary wheels for as many platforms as possible.
### Disabling Vendored Code
A copy of [*Argon2*] is vendored and used by default, but can be disabled if *argon2-cffi-bindings* is installed using:
```console
$ env ARGON2_CFFI_USE_SYSTEM=1 \
python -m pip install --no-binary=argon2-cffi-bindings argon2-cffi-bindings
```
### Overriding Automatic *SSE2* Detection
Usually the build process tries to guess whether or not it should use [*SSE2*](https://en.wikipedia.org/wiki/SSE2)-optimized code (see [`_ffi_build.py`](https://github.com/hynek/argon2-cffi-bindings/blob/main/src/_argon2_cffi_bindings/_ffi_build.py) for details).
This can go wrong and is problematic for cross-compiling.
Therefore you can use the `ARGON2_CFFI_USE_SSE2` environment variable to control the process:
- If you set it to ``1``, *argon2-cffi-bindings* will build **with** SSE2 support.
- If you set it to ``0``, *argon2-cffi-bindings* will build **without** SSE2 support.
- If you set it to anything else, it will be ignored and *argon2-cffi-bindings* will try to guess.
However, if our heuristics fail you, we would welcome a bug report.
### Python API
Since this package is intended to be an implementation detail, it uses a private module name to prevent your users from using it by accident.
Therefore you have to import the symbols from `_argon2_cffi_bindings`:
```python
from _argon2_cffi_bindings import ffi, lib
```
Please refer to [*cffi* documentation](https://cffi.readthedocs.io/en/latest/using.html) on how to use the `ffi` and `lib` objects.
The list of symbols that are provided can be found in the [`_ffi_build.py` file](https://github.com/hynek/argon2-cffi-bindings/blob/main/src/_argon2_cffi_bindings/_ffi_build.py).

*argon2-cffi-bindings* is available under the MIT license, available from [PyPI](https://pypi.org/project/argon2-cffi-bindings/), the source code and documentation can be found on [GitHub](https://github.com/hynek/argon2-cffi-bindings).
*argon2-cffi-bindings* targets Python 3.6 and later, including PyPy3.
### Credits & License
*argon2-cffi-bindings* is written and maintained by [Hynek Schlawack](https://hynek.me/about/).
It is released under the [MIT license](https://github.com/hynek/argon2-cffi/blob/main/LICENSE>).
The development is kindly supported by [Variomedia AG](https://www.variomedia.de/).
The authors of *Argon2* were very helpful to get the library to compile on ancient versions of Visual Studio for ancient versions of Python.
The documentation quotes frequently in verbatim from the *Argon2* [paper](https://www.password-hashing.net/argon2-specs.pdf) to avoid mistakes by rephrasing.
