Ephemeral Diffie-Hellman Over COSE (EDHOC)
Project description
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:

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 ocse uses python-ecdsa.
