Struct lockchain_core::crypto::Key

pub struct Key { /* fields omitted */ }

A crytographic key of a certain type

Uses a union to allow key inlining without heap allocation. Provides easy to use constructors for generation and derivation from user input/name.

Also implements serde::{Serialize, Deserialize} via a custom serialiser which allows easy encryption of the key itself.

Methods

impl Key

pub fn new(tt: KeyType) -> Key

Generate a new, completely random key of a certain type

pub fn from_pw(tt: KeyType, pw: &str, user: &str) -> Key

Generate a new key based on a user password

This function uses the pbkdf2 algorithm to deterministically expand an input pw/username combination into a key.

Trait Implementations

impl Serialize for Key

fn serialize<S>(     &self,     serializer: S ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error> where     S: Serializer,

Serialize this value into the given Serde serializer.

impl Debug for Key

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

Formats the value using the given formatter.

impl Eq for Key

impl PartialEq<Key> for Key

fn eq(&self, o: &Key) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

impl<'de> Deserialize<'de> for Key

fn deserialize<D>(     deserializer: D ) -> Result<Key, <D as Deserializer<'de>>::Error> where     D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl AutoEncoder for Key

fn encode(&self) -> Result<String, SerdeError>

fn decode(s: &str) -> Result<Self, SerdeError>
