Struct PayloadKey 

pub struct PayloadKey(/* private fields */);

Payload encryption key derived from CEK and header salt.

Implementations

impl PayloadKey

pub fn from_bytes(bytes: [u8; 32]) -> Self

Take ownership of existing bytes.

pub fn random<R: CryptoRng + ?Sized>(rng: &mut R) -> Self

Generate using the supplied RNG.

The RNG is passed as an argument, not obtained from the environment: otherwise tests cease to be deterministic, and Wycheproof vectors cannot exercise our own call sites.

pub fn expose(&self) -> &[u8; 32]

Expose bytes. Deliberately verbose: the call must stand out during code reading and review.

Trait Implementations

impl Clone for PayloadKey

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PayloadKey

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

Formats the value using the given formatter.

impl Drop for PayloadKey

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Zeroize for PayloadKey

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
