Tuple Fields

0: AesKey

Implementations

impl TemporalKey

pub fn derive_snapshot_key(&self) -> SnapshotKey

Turn this TemporalKey, which gives read access to the current revision and any future revisions into a SnapshotKey, which only gives read access to the current revision.

pub fn key_wrap_encrypt(&self, cleartext: &[u8]) -> Result<Vec<u8>>

Encrypt a cleartext with this temporal key.

Uses authenticated deterministic encryption via AES key wrap with padding (AES-KWP).

The resulting ciphertext is 8 bytes longer than the next multiple of 8 bytes of the cleartext input length.

pub fn key_wrap_decrypt(&self, ciphertext: &[u8]) -> Result<Vec<u8>>

Decrypt a ciphertext that was encrypted with this temporal key.

Uses authenticated deterministic encryption via AES key wrap with padding (AES-KWP).

The input ciphertext is 8 bytes longer than the next multiple of 8 bytes of the resulting cleartext length.

Trait Implementations

impl Clone for TemporalKey

fn clone(&self) -> TemporalKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TemporalKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TemporalKey

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&Ratchet> for TemporalKey

fn from(ratchet: &Ratchet) -> Self

Converts to this type from the input type.

impl From<[u8; 32]> for TemporalKey

fn from(key: [u8; 32]) -> Self

Converts to this type from the input type.

impl From<AesKey> for TemporalKey

fn from(key: AesKey) -> Self

Converts to this type from the input type.

impl PartialEq<TemporalKey> for TemporalKey

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for TemporalKey

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

Serialize this value into the given Serde serializer.
