Struct MasterKey 

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

A crypto_kdf master key. Always exactly 32 bytes - Kupyna256Kdf’s fixed key length (see the module doc).

Implementations

impl MasterKey

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

Generates a fresh master key from the OS CSPRNG - libsodium’s crypto_kdf_keygen equivalent.

Errors

Returns crate::randombytes::RandomError if the OS CSPRNG fails.

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

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

pub fn derive_subkey(&self, subkey_id: u64, context: &[u8; 8]) -> [u8; 32]

Derives a subkey - see Kupyna256Kdf::derive_subkey for the construction itself. Different subkey_id/context values (holding the others fixed) produce different subkeys.

Trait Implementations

impl Drop for MasterKey

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.
