Struct Attributes 

pub struct Attributes<'a, D> { /* private fields */ }

Represents a collection of attribute values and that can be hardened into a Keyspace using memory-hard key derivation.

Implementations

impl<'a, D> Attributes<'a, D>

where D: Digest + CoreProxy + OutputSizeUser + Sync, D::Core: Sync + HashMarker + UpdateCore + FixedOutputCore + BufferKindUser<BufferKind = Eager> + Default + Clone + BlockSizeUser, <D::Core as BlockSizeUser>::BlockSize: IsLess<U256>, Le<<D::Core as BlockSizeUser>::BlockSize, U256>: NonZero,

pub fn new(arr: Vec<Vec<u8>>, params: Params) -> Result<Self, ArrkeyError>

Construct a new collection of Attributes.

Requires at least two attribute values, and a set of valid parameters. Returns an error when fewer than two attributes are provided.

pub fn harden(&self, salt: &[u8]) -> Result<Keyspace<D>, ArrkeyError>

Harden the attributes into a cryptographic Keyspace.

Applies a memory-hard key derivation function (Argon2id) to harden all attributes in parallel, using per-attribute salts derived from a shared base salt. All hardened attributes are used to produce a keyspace, from which attribute-based keys can be selected.

Returns a Keyspace of the hardened attributes on success, or an error when the memory-hard key derivation process fails.

pub fn len(&self) -> usize

Return the number of attributes in this collection.

Trait Implementations

impl<'a, D: Clone> Clone for Attributes<'a, D>

fn clone(&self) -> Attributes<'a, D>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, D: Debug> Debug for Attributes<'a, D>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
