Pure Python code is located in cry/py package and can be imported from python code. The other modules must be imported from the SageMath interpreter.\n\nThe most significant part is formed by S-Box analysis algorithms, implemented in the cry.sbox2.SBox2 class, which is similar to from sage.crypto.SBox but is much more rich. Another cool S-Box library is [SboxU](https://github.com/lpp-crypto/sboxU) by Léo Perrin. It contains some more advanced algorithms, highly recommended!\n\n**WARNING:** This library is not well-shaped yet and many things (including API and structure) may change in future. For now, I will try to keep compatability only for minor versions. That is, lock to the minor version if you use this package.\n\n**NOTE** Before, this library was called *cryptools*, but since this name is used on PyPI, I decided to switch to *cry*, which is shorter.\n\nCurrently, there is no documentation but examples will be added soon.\n\n## Installation\n\n```bash\n# for SageMath\n$ sage pip install -U cry\n# for python3\n$ pip3 install -U cry\n```\n\nPrevious python2 version (cryptools) can be found in the tag *py2-arhived*.\n\n## Development\n\nFor development or building this repository, [poetry](https://python-poetry.org/) is needed.\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhellman%2Fcry","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fhellman%2Fcry","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhellman%2Fcry/lists"}
