Struct ReceiverMac 

pub struct ReceiverMac {
    pub key_id: u32,
    pub mac: [u8; 16],
}

Receiver-Specific-MAC (Spec §7.3.6.3 ReceiverSpecificMAC).

Wenn ein Sender ein Ciphertext an N Receiver mit gleicher Suite aber unterschiedlichen Keys schickt, wird pro Receiver ein 16-byte Truncated-HMAC berechnet. Die Wire-Repraesentation ist eine Sequenz von (key_id, mac)-Paaren im SEC_POSTFIX.

key_id ist die Spec-konforme 4-Byte-ID (typisch low-32-bits des Sender-seitigen CryptoHandle fuer diesen Receiver), anhand derer der Empfaenger seinen spezifischen MAC-Eintrag findet.

Fields

key_id: u32

4-byte CryptoTransformKeyId aus §7.3.6.3.

mac: [u8; 16]

16-byte Truncated-HMAC-SHA256 ueber den Ciphertext.

Implementations

impl ReceiverMac

pub const WIRE_SIZE: usize

Wire-Size eines einzelnen ReceiverMac-Eintrags (Spec §7.3.6.3).

Trait Implementations

impl Clone for ReceiverMac

fn clone(&self) -> ReceiverMac

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReceiverMac

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

Formats the value using the given formatter.

impl Hash for ReceiverMac

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ReceiverMac

fn eq(&self, other: &ReceiverMac) -> 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.
