Testing Milestone 2

Verifying Features

First, run Fennel Protocol as a dev node:

$ ./scripts/setup.sh
$ ./scripts/build-run.sh

Extrinsics are available by navigating to Polkadot.js and entering the Developer > Extrinsics menu.

The following represent the features outlined as the deliverables outlined for Milestone 2:

Key Creation

Given key and location, the Key Announcement extrinsic will insert a Storage entry announcing the existence of a Key to the Issued Key's list of keys.

Public Key Transmission

You can announce a new RSA public key to the network by calling the issue_key extrinsic (source) with a key fingerprint and a link to a public key storage location.

Public Key Retrieval

Public Key Retrieval is implemented as a storage handler around a StorageDoubleMap, mapping accounts to key fingerprints to storage locations. You can find an example of a Rust function to call against this storage endpoint in fennel-lib.

Encrypted Communication Channel Negotiation

The changes in this milestone include both a library used to integrate key management and encryption negotiation features into Rust-based applications through a new fennel-lib implementation, and a Fennel Protocol pallet used to announce both Diffie-Hellman public keys and RSA public keys to the network. In the next milestone, we'll complete a client/server pair targeting easy deployment with this library integrated.

AES

Fennel provides support in our integration libraries for AES encryption and the generation of AES keys. A light wrapper around the OpenSSL implementation of AES is used for both key generation and encryption/decryption.
