Struct KdfDerivedKeyMaterial

pub struct KdfDerivedKeyMaterial(pub(super) Pin<Box<GenericArray<u8, U32>>>);

Holding struct for key material derived from a KDF.

The internal key material should not be used directly for cryptographic operations. Instead it MUST be converted to the appropriate type such as SymmetricCryptoKey, MasterKey or any other key type. This can be done by either directly consuming the key material or by stretching it further using HKDF (HMAC-based Key Derivation Function).

Uses a pinned heap data structure, as noted in Pinned heap data

Implementations

impl KdfDerivedKeyMaterial

pub(super) fn derive_kdf_key( secret: &[u8], salt: &[u8], kdf: &Kdf, ) -> Result<Self, CryptoError>

Derive a key from a secret and salt using the provided KDF.

pub(super) fn derive( password: &str, email: &str, kdf: &Kdf, ) -> Result<Self, CryptoError>

Derives a users master key from their password, email and KDF.

Note: the email is trimmed and converted to lowercase before being used.

Trait Implementations

impl From<KdfDerivedKeyMaterial> for MasterKey

fn from(key: KdfDerivedKeyMaterial) -> Self

Converts to this type from the input type.
