Struct SecretKey 

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

A crypto_box private key - the DSTU 9041 scalar e.

Implementations

impl SecretKey

pub fn from_bytes(e: &[u8; 32]) -> Option<Self>

Builds a secret key from a big-endian 32-byte scalar. Returns None if it’s outside the valid range {2, ..., n-2} (hazmat::dstu9041::curve256::is_valid_scalar).

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

Generates a fresh secret key from the OS CSPRNG - libsodium’s crypto_box_keypair() equivalent (its public-key half is Self::public_key).

Errors

Returns RandomError if the OS CSPRNG fails while drawing a candidate.

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

Returns e’s big-endian 32-byte encoding, so a generated key can be persisted and later reloaded via Self::from_bytes. The caller becomes responsible for zeroizing the returned array once done with it.

pub fn public_key(&self) -> PublicKey

Trait Implementations

impl Drop for SecretKey

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.
