Summary
Functions
Mix and expand the sender and receiver entropy inputs into a nonce using CKDF-MEI.
Computes an ECDH public key for the given private key.
Encode the ECDH public key into a DSK string.
Computes the shared secret using the ECDH algorithm with the local node's private key and the remote node's public key (as reported by S2 Public Key Report).
Expands a network key into a CCM key for encryption and authorization, a personalization string, and an MPAN key using the CKDF-Expand algorithm as described in https://datatracker.ietf.org/doc/html/draft-moskowitz-hip-dex-02#section-6.3.
Expands a network key into a CCM key for encryption and authorization, a personalization string, and an MPAN key using the CKDF-Expand algorithm as described in https://datatracker.ietf.org/doc/html/draft-moskowitz-hip-dex-02#section-6.3.
Expands a temporary network key into a CCM key for encryption and authorization, a personalization string, and an MPAN key using the CKDF-Expand algorithm as described in https://datatracker.ietf.org/doc/html/draft-moskowitz-hip-dex-02#section-6.3.
