Crate hopr_crypto_packet 

core-packet

This crate contains the main packet processing functionality for the HOPR protocol. It implements the following important protocol building blocks:

• HOPR specific instantiation of the SPHINX packet format
• Proof of Relay

Finally, it also implements a utility function which is used to validate tickets (module validation).

The currently used implementation is selected using the HoprSphinxSuite type in the packet module.

The implementation can be easily extended for different elliptic curves (or even arithmetic multiplicative groups). In particular, as soon as there is a way to represent Ed448 PeerIDs, it would be straightforward to create e.g. X448Suite.

This crate implements RFC-0003.
