An (interim) JOSE library, featuring support for Ed25519, X25519, ChaCha20/Poly1305 and AES256-GCM as required for PyKauriID.
To install use pip:
$ pip install sspyjose
Or clone the repo:
$ git clone https://gitlab.com/kauriid/sspyjose.git
$ python setup.py install
Set up and activate for Python 3:
virtualenv ${HOME}/.virtualenvs/sspyjose \
--system-site-packages --python=/usr/bin/python3
source ${HOME}/.virtualenvs/sspyjose/bin/activate
Install required packages:
pip install -e .
For installing the additional development, testing or documentation dependencies, add a qualifier with one or more of these commands:
pip install -e .[dev] # Development dependencies
pip install -e .[test] # Testing dependencies
pip install -e .[dev,test] # All dependencies together

# The JWK must contain the private key seed.
