Struct TransactionEncryptionKey 

pub struct TransactionEncryptionKey {
    pub scheme: i32,
    pub key_id: Vec<u8>,
    pub public_key: Vec<u8>,
    pub attestations: Vec<ValidatorKeyAttestation>,
    pub next_key: Option<NextTransactionEncryptionKey>,
}

The shared transaction encryption key, attested by validators.

The public key is shared across the whole validator set, while each attesting signature is specific to one validator. Verifying an attestation against a chain-recognized validator signing key proves the encryption key was vouched for by a legitimate validator.

Fields

scheme: i32

IES scheme the encryption key belongs to.

Currently always IES_SCHEME_X25519_XCHACHA20_POLY1305.

key_id: Vec<u8>

Opaque identifier of the current encryption key. Changes when the key rotates.

public_key: Vec<u8>

Raw public key bytes of the shared encryption key.

For the X25519 scheme these are the 32 bytes produced by [miden_protocol::crypto::dsa::eddsa_25519_sha512::PublicKey::to_bytes] (an Ed25519 public key that miden-crypto converts internally for X25519 key agreement).

attestations: Vec<ValidatorKeyAttestation>

Validator attestations of this key (and of next_key when set).

Contains the attestation from the validator that served the request. The wire format permits attestations from multiple validators.

next_key: Option<NextTransactionEncryptionKey>

Set when a key rotation is scheduled: the key that replaces the current one, and the block number at which it takes effect. Covered by the attestation commitment, so it cannot be stripped or altered without invalidating the signatures.

The server does not set this field because it does not support key rotation.

Implementations

impl TransactionEncryptionKey

pub fn scheme(&self) -> IesScheme

Returns the enum value of scheme, or the default if the field is set to an invalid enum value.

pub fn set_scheme(&mut self, value: IesScheme)

Sets scheme to the provided enum value.
