Struct TransformKey

pub struct TransformKey { /* private fields */ }

TransformKeys allow a message encrypted to one public key (the key of the delegator) to be transformed and appear as if it was encrypted to another public key (the key of hte delegatee), or put another way, a TransformKey changes which private_key can decrypt the data.

TransfomKeys cannot, themselves, decrypt any data!

ephemeral_public_key - ephemeral key unique to this TransforKey. Key that encrypted the encrypted_k value to_public_key - public key of the delagatee encrypted_k - random value K, encrypted to the delegatee; used to un-roll successive levels of multi-hop transform encryption hashed_k - combination of the hash of K and the secret key of the delegator; used to recover K from encrypted_k

Implementations

impl TransformKey

pub fn ephemeral_public_key(&self) -> &PublicKey

pub fn to_public_key(&self) -> &PublicKey

pub fn encrypted_temp_key(&self) -> &EncryptedTempKey

pub fn hashed_temp_key(&self) -> &HashedValue

pub fn public_signing_key(&self) -> &PublicSigningKey

pub fn signature(&self) -> &Ed25519Signature

pub fn new( ephemeral_public_key: PublicKey, to_public_key: PublicKey, encrypted_temp_key: EncryptedTempKey, hashed_temp_key: HashedValue, public_signing_key: PublicSigningKey, signature: Ed25519Signature, ) -> TransformKey

Public constructor. See TransformKey.

pub fn augment( &self, private_key: &PrivateKey, ) -> Result<TransformKey, RecryptErr>

Augment the TransformKey using private_key. If the private_key the TransformKey was delegating from was unaugmented this can be used to make the TransformKey useful for delegation.

Trait Implementations

impl Clone for TransformKey

fn clone(&self) -> TransformKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransformKey

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

Formats the value using the given formatter.

impl Hash for TransformKey

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

where __H: Hasher,

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 Hashable for TransformKey

fn to_bytes(&self) -> ByteVector

Convert self to a stable byte representation.

impl PartialEq for TransformKey

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