OxiCrypt

This is one of my abandoned projects. I started this when Rust didn't have the features I wanted in my library. However, it does seem to me that they added really coold features which I would like to try. I will get around to working on this library eventually. But please, DO NOT USE THIS LIBRARY FOR SERIOUS THINGS. It is just a hobby project.

---

A cryptography library that is mainly implemented in Rust. I aim to implement bindings to other languages such as C/C++ and Python. This project is just to learn more about cryptographic algorithms and experimenting with FFI. I don't know much about cryptography, so if you want to use a cryptography library you should use other libraries that are well-tested and written by people who know their stuff.

Structure of this library

This library contains the following crates:

• oxicrypt includes the source files for the Rust API. It implements the high level API.
• oxicrypt_c is the C/C++ API. The C API is built using meson, which enables the c feature during compilation to activate parts of the library that implement the C interface.
• oxicrypt_core is the crate the implements the low level functions. Things like the compression functions for the digest algorithms or the raw AES functions for different kinds of architectures as well as generic implementations are handled by this library. You need not interface with this library directly unless you need low level access.
• oxicrypt_python implements the FFI between Rust and Python. The crate exposes the FFI module with the help of PyO3. The Python module imports the FFI crate and implements a higher level API for Python.
• oxicrypt_test includes test vectors for the algorithms. This crate is only used when in development mode.

Installation

Rust

Put the following in your Cargo.toml.

oxicrypt = { version = "0.1", git = "https://github.com/byhowe/oxicrypt.git" }

C/C++

Run the following commands to install the headers, a static library and a shared library.

$ meson --prefix /usr --buildtype release --default-library both target
$ meson install -C target

Python

Currently, the Python API does not expose much. That being said, much of the functionality of OxiCrypt will be included. The current Python module can be installed with the following command.

$ cd oxicrypt_python
$ maturin build
$ pip install ../target/wheels/oxicrypt-0.1.0-cp310-cp310-manylinux_2_34_x86_64.whl

Maturin will generate a wheel file that is usually located under the target directory. Based on the output of Maturin, change the path to the wheel file accordingly.
