Struct Journalist 

pub struct Journalist { /* private fields */ }

Journalists: ingredients. Journalists have a signing/verifying key, a reply key, a fetch key, and a collection of one-time signed key bundles

Implementations

impl Journalist

pub fn new<R: RngCore + CryptoRng>(rng: &mut R, num_keybundles: usize) -> Self

pub fn public(&self, idx: usize) -> JournalistPublicView

pub fn long_term_bytes(&self) -> JournalistLongTermBytes

Extract the long-term keypairs as raw bytes, sufficient to reconstruct the long-term Journalist state via Journalist::from_long_term_bytes.

pub fn from_long_term_bytes(parts: JournalistLongTermBytes) -> Self

Reconstruct the long-term Journalist state from raw key bytes.

pub fn generate_ephemeral_bundles<R: RngCore + CryptoRng>( &mut self, rng: &mut R, n: usize, )

Generate n fresh signed ephemeral key bundles and retain them in memory.

The public halves are uploaded to the server via create_ephemeral_key_request.

The secret halves should be persisted via Journalist::ephemeral_bundle_bytes.

pub fn ephemeral_bundle_bytes(&self) -> Vec<EphemeralBundleBytes>

Extract the secret halves of the retained ephemeral key bundles so we can reconstruct them via Journalist::load_ephemeral_bundles.

Used by the demo.

pub fn load_ephemeral_bundles(&mut self, bundles: Vec<EphemeralBundleBytes>)

Reconstruct ephemeral key bundles from persisted secret bytes.

Used by the demo
