Struct Seed

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

Implementations

impl Seed

pub const SIZE: usize = 32usize

pub fn generate<RNG>(rng: &mut RNG) -> Self

where RNG: RngCore + CryptoRng,

Generate a random see with the given Cryptographically secure Random Number Generator (RNG).

This is useful to generate one time only Seed that does not need to be remembered or saved.

pub fn derive_from_key<K, P>(key: K, password: P) -> Self

where K: AsRef<[u8]>, P: AsRef<[u8]>,

it is possible to derive the Seed from a given key

the key may be given by a secure hardware or simply be a mnemonic phrase given by a user and a password.

It is possible, but not recommended, that the password is left empty. However, the key needs to be large enough to generate enough entropy for the derived seed.

pub fn into_rand_chacha(self) -> ChaChaRng

use this to seed a ChaCha RNG

then you can use the RNG to create new private key. This is an handy way to derive a private key from a key and a password (or an HSM and a password?)

Trait Implementations

impl AsRef<[u8]> for Seed

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Seed

fn clone(&self) -> Seed

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Seed

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

Formats the value using the given formatter.

impl Display for Seed

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

Formats the value using the given formatter.

impl Drop for Seed

fn drop(&mut self)

Executes the destructor for this type.

impl From<[u8; 32]> for Seed

fn from(seed: [u8; 32]) -> Self

Converts to this type from the input type.

impl FromStr for Seed

type Err = FromHexError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.
