Struct SecretBundle 

pub struct SecretBundle;

Available on crate features data_scheme only.

Bundle of all secrets used by a group to encrypt and decrypt it’s data.

Peers manage all secrets they generated or learned about in this bundle. New secrets are added to the bundle when a group got updated, a member was added or removed.

Secrets inside the bundle can be removed if the application considers them due, otherwise a bundle will grow in size and no forward secrecy is given.

Implementations

impl SecretBundle

pub fn init() -> SecretBundleState

Initialises empty secret bundle state.

pub fn from_secrets(secrets: Vec<GroupSecret>) -> SecretBundleState

Initialises secret bundle state from a list of group secrets.

pub fn generate( y: &SecretBundleState, rng: &Rng, ) -> Result<GroupSecret, GroupSecretError>

Generates and returns a new secret.

To prevent issues with invalid timestamps (too far in the future) of previous secrets, we force our newly generated secret to be the “latest” when needed.

The secret is not yet inserted into the bundle, this needs to be done manually.

pub fn insert(y: SecretBundleState, secret: GroupSecret) -> SecretBundleState

Inserts secret into bundle, ignoring duplicates.

pub fn remove( y: SecretBundleState, id: &GroupSecretId, ) -> (SecretBundleState, Option<GroupSecret>)

Removes secret from bundle.

pub fn extend( y: SecretBundleState, other: SecretBundleState, ) -> SecretBundleState

Merges one bundle with another, ignoring duplicates.
