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-05

$ pip install edhoc

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

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.
