Implementations§

source§

impl Pair

source

pub fn verify_deprecated<M>( sig: &Signature, message: M, pubkey: &Public ) -> boolwhere M: AsRef<[u8]>,

source§

impl Pair

source

pub fn make_bytes<const N: usize>( &self, context: &[u8], input: &VrfTranscript ) -> [u8; N]where [u8; N]: Default,

Generate output bytes from the given VRF configuration.

source§

fn from_seed_slice(seed: &[u8]) -> Result<Pair, SecretStringError>

Make a new key pair from raw secret seed material.

A MiniSecretKey is literally what Ed25519 calls a SecretKey, which is just 32 random bytes.

§

type Public = Public

§

type Seed = [u8; 32]

The type used to (minimally) encode the data required to securely create a new key pair.
§

type Signature = Signature

The type used to represent a signature. Can be created from a key pair and a message and verified with the message and a public key.
source§

fn derive<Iter>( &self, path: Iter, seed: Option<[u8; 32]> ) -> Result<(Pair, Option<[u8; 32]>), DeriveError>where Iter: Iterator<Item = DeriveJunction>,

Derive a child key from a series of given junctions.
source§

fn sign(&self, message: &[u8]) -> Signature

Sign a message.
source§

fn verify<M>(sig: &Signature, message: M, pubkey: &Public) -> boolwhere M: AsRef<[u8]>,

Verify a signature on a message. Returns true if the signature is good.
source§

fn to_raw_vec(&self) -> Vec<u8>

source§

fn from_phrase( phrase: &str, password: Option<&str> ) -> Result<(Self, Self::Seed), SecretStringError>

Returns the KeyPair from the English BIP39 seed phrase, or an error if it’s invalid.
source§

fn from_seed(seed: &Self::Seed) -> Self

Generate new key pair from the provided seed. Read more
source§

fn from_string_with_seed( s: &str, password_override: Option<&str> ) -> Result<(Self, Option<Self::Seed>), SecretStringError>

Interprets the string s in order to generate a key Pair. Returns both the pair and an optional seed, in the case that the pair can be expressed as a direct derivation from a seed (some cases, such as Sr25519 derivations with path components, cannot). Read more
source§

fn from_string( s: &str, password_override: Option<&str> ) -> Result<Self, SecretStringError>

Interprets the string s in order to generate a key pair. Read more
source§

impl VrfCrypto for Pair

§

type VrfInput = VrfTranscript

§

type VrfOutput = VrfOutput
