Implementations

impl SecretKey

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

Create from raw bytes (e.g., from HKDF output).

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

View the raw bytes for use in HMAC/HKDF — no copy.

Trait Implementations

impl Drop for SecretKey

fn drop(&mut self)

Executes the destructor for this type.

impl Zeroize for SecretKey

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.
