Struct TreasureMap

pub struct TreasureMap {
    pub threshold: u8,
    pub hrac: HRAC,
    pub destinations: BTreeMap<Address, EncryptedKeyFrag>,
    pub policy_encrypting_key: PublicKey,
    pub publisher_verifying_key: PublicKey,
}

A structure containing KeyFrag objects encrypted for Ursulas chosen for this policy.

Fields

threshold: u8

Threshold for successful re-encryption.

hrac: HRAC

Policy HRAC.

destinations: BTreeMap<Address, EncryptedKeyFrag>

Encrypted key frags assigned to target Ursulas.

policy_encrypting_key: PublicKey

A key to create encrypted messages under this policy.

publisher_verifying_key: PublicKey

Publisher’s verifying key.

Implementations

impl TreasureMap

pub fn new( signer: &Signer, hrac: &HRAC, policy_encrypting_key: &PublicKey, assigned_kfrags: impl IntoIterator<Item = (Address, (PublicKey, VerifiedKeyFrag))>, threshold: u8, ) -> Self

Create a new treasure map for a collection of ursulas and kfrags.

Panics if threshold is set to 0, the number of assigned keyfrags is less than threshold, or if the addresses in assigned_kfrags repeat.

pub fn encrypt( &self, signer: &Signer, recipient_key: &PublicKey, ) -> EncryptedTreasureMap

Encrypts the treasure map for Bob.

pub fn make_revocation_orders(&self, signer: &Signer) -> Vec<RevocationOrder>

Makes revocation orders for all destinations in the treasure map.

Trait Implementations

impl Clone for TreasureMap

fn clone(&self) -> TreasureMap

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TreasureMap

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TreasureMap

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TreasureMap

fn eq(&self, other: &TreasureMap) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> ProtocolObject<'a> for TreasureMap

fn version() -> (u16, u16)

supported by the current implementation.

fn to_bytes(&self) -> Box<[u8]>

Serializes the object.

fn from_bytes(bytes: &'a [u8]) -> Result<Self, DeserializationError>

Attempts to deserialize the object.

impl Serialize for TreasureMap

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
