Struct TransactionEncryptionKey 

pub struct TransactionEncryptionKey { /* private fields */ }

The validator set’s public transaction encryption key, with its attestation already verified.

Holds public key material only, and is shared by every validator in the set; the matching secret never leaves the validators.

Only AttestedTransactionEncryptionKey::verify constructs one, so a key that reaches the seal path has necessarily been vouched for by a chain-recognized validator.

Implementations

impl TransactionEncryptionKey

pub fn key_id(&self) -> &[u8]

Returns the node’s opaque identifier for this key.

The identifier changes when the key rotates, which is what lets a cached key be recognized as stale. It is treated as opaque bytes: the node derives it from the public key commitment but documents the encoding as an implementation detail.

pub fn public_key(&self) -> &PublicKey

Returns the public key.

pub fn sealing_key(&self) -> SealingKey

Builds the sealing key used to encrypt transaction inputs against this key.

pub fn new_unattested( key_id: Vec<u8>, public_key: PublicKey, genesis_commitment: Word, ) -> Self

Available on crate feature testing only.

Builds a key without an attestation, for tests.

Sealing against the returned key still runs the real transcript and wire path, only the attestation is skipped, and that is covered by this module’s own tests.

Trait Implementations

impl Clone for TransactionEncryptionKey

fn clone(&self) -> TransactionEncryptionKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionEncryptionKey

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

Formats the value using the given formatter.

impl Deserializable for TransactionEncryptionKey

fn read_from<R: ByteReader>( source: &mut R, ) -> Result<Self, DeserializationError>

Reads a sequence of bytes from the provided source, attempts to deserialize these bytes into Self, and returns the result.

fn min_serialized_size() -> usize

Returns the minimum serialized size for one instance of this type.

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

Attempts to deserialize the provided bytes into Self and returns the result.

fn read_from_bytes_with_budget( bytes: &[u8], budget: usize, ) -> Result<Self, DeserializationError>

Deserializes Self from bytes with a byte budget limit.

impl Eq for TransactionEncryptionKey

impl PartialEq for TransactionEncryptionKey

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

Equality operator ==.

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

Inequality operator !=.

impl Serializable for TransactionEncryptionKey

fn write_into<W: ByteWriter>(&self, target: &mut W)

Serializes self into bytes and writes these bytes into the target.

fn to_bytes(&self) -> Vec<u8>

Serializes self into a vector of bytes.

fn get_size_hint(&self) -> usize

Returns an estimate of how many bytes are needed to represent self.
