Struct DomainKey 

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

A random symmetric key for one domain epoch.

Implementations

impl DomainKey

pub fn generate() -> Result<Self, SecurityError>

Generates a key from the operating system’s cryptographic random source.

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

Imports exact key bytes from a trusted key provider.

pub fn derive_subkey( &self, salt: &[u8], context: &[u8], ) -> Result<Zeroizing<[u8; 32]>, SecurityError>

Derives a domain-separated object key without exposing the epoch key.

Trait Implementations

impl Clone for DomainKey

fn clone(&self) -> DomainKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DomainKey

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

Formats the value using the given formatter.

impl Drop for DomainKey

fn drop(&mut self)

Executes the destructor for this type.

impl Zeroize for DomainKey

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.
