py-edhoc:snake: -- Ephemeral Diffie-Hellman Over COSE
This project provides a Python implementation of the EDHOC key exchange protocol for constrained devices. Currently the protocol is still in draft status at the IETF.
The repository provides an implementation of:
- https://datatracker.ietf.org/doc/html/draft-ietf-lake-edhoc-01
- https://datatracker.ietf.org/doc/html/draft-ietf-lake-edhoc-02
Installation
$ pip install edhoc
Running the test suite
The py-edhoc test suite is based on the official test vectors provided by the LAKE working group.
To run the test suite you'll need pytest:
$ pip install pytest
When you move to the root of the py-edhoc project you can run the test by simply typing:
$ pytest

Cryptography
The project depends on the python cose package. cose uses pyca/cryptography for all cryptographic operations, except the deterministic ECDSA algorithm. For deterministic ECDSA cose uses python-ecdsa.
