pub struct Pair(_);

Expand description

An Schnorrkel/Ristretto x25519 (“sr25519”) key pair.

Implementations

[src]

impl Pair

[src]

pub fn from_entropy(entropy: &[u8], password: Option<&str>) -> (Pair, [u8; 32])

Make a new key pair from binary data derived from a valid seed phrase.

This uses a key derivation function to convert the entropy into a seed, then returns the pair generated from it.

[src]

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

Verify a signature on a message. Returns true if the signature is good. Supports old 0.1.1 deprecated signatures and should be used only for backward compatibility.

impl Pair for Pair

[src]

pub fn from_seed(seed: &[u8; 32]) -> Pair

Make a new key pair from raw secret seed material.

This is generated using schnorrkel’s Mini-Secret-Keys.

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

[src]

pub fn public(&self) -> Public

Get the public key.

[src]

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

Make a new key pair from secret seed material. The slice must be 32 bytes long or it will return None.

You should never need to use this; generate(), generate_with_phrase(), from_phrase()

type Public = Public

type Seed = [u8; 32]

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

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. Read more

type DeriveError = Infallible

Error returned from the derive function.

[src]

pub fn generate_with_phrase(password: Option<&str>) -> (Pair, String, [u8; 32])

    phrase: &str, 
    password: Option<&str>
) -> Result<(Pair, [u8; 32]), SecretStringError>

[src]

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

Derive a child key from a series of given junctions.

[src]

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

[src]

pub fn verify<M>(
    sig: &<Pair as Pair>::Signature,

pub fn verify_weak<P, M>(sig: &[u8], message: M, pubkey: P) -> bool where
    M: AsRef<[u8]>,
    P: AsRef<[u8]>,

pub fn to_raw_vec(&self) -> Vec<u8, Global>

Return a vec filled with raw data.

[src]

fn generate() -> (Self, Self::Seed)

[src]

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

[src]

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