Trait Implementations

impl AlgorithmFactory for KDFFactory

fn default_128_bit() -> Self

Get the default configured algorithm at the 128-bit security level.

fn default_256_bit() -> Self

Get the default configured algorithm at the 256-bit security level.

fn new(alg_name: &str) -> Result<Self, FactoryError>

Create an instance of the algorithm by name.

impl Default for KDFFactory

fn default() -> Self

Returns the “default value” for a type.

impl KDF for KDFFactory

fn derive_key( self, key: &impl KeyMaterial, additional_input: &[u8], ) -> Result<Box<dyn KeyMaterial>, KDFError>

Implementations of this function are capable of deriving an output key from an input key, assuming that they have been properly initialized.

fn derive_key_out( self, key: &impl KeyMaterial, additional_input: &[u8], output_key: &mut impl KeyMaterial, ) -> Result<usize, KDFError>

Same as KDF::derive_key, but fills the provided output KeyMaterialInternal.

fn derive_key_from_multiple( self, keys: &[&impl KeyMaterial], additional_input: &[u8], ) -> Result<Box<dyn KeyMaterial>, KDFError>

Meant to be used for hybrid key establishment schemes or other spit-key scenarios where multiple keys need to be combined into a single key of the same length.

fn derive_key_from_multiple_out( self, keys: &[&impl KeyMaterial], additional_input: &[u8], output_key: &mut impl KeyMaterial, ) -> Result<usize, KDFError>

Same as KDF::derive_key, but fills the provided output KeyMaterialInternal.

fn max_security_strength(&self) -> SecurityStrength

Returns the maximum security strength that this KDF is capable of supporting, based on the underlying primitives.
