Expand description

A key pair.

Implementations

source

impl Pair

source

pub fn seed(&self) -> [u8 ; 32]

Get the seed for this key.

source

pub fn from_legacy_string(s: &str, password_override: Option<&str>) -> Pair

Exactly as from_string except that if no matches are found then, the the first 32 characters are taken (padded with spaces as necessary) and used as the MiniSecretKey.

source

pub fn sign_prehashed(&self, message: &[u8 ; 32]) -> Signature

Sign a pre-hashed message

source

pub fn verify_prehashed(
    sig: &Signature,
    message: &[u8 ; 32],
    public: &Public
) -> bool

Verify a signature on a pre-hashed message. Return true if the signature is valid and thus matches the given public key.

source

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. Parses Signature using parse_overflowing_slice

source

impl Pair for Pair

source

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

Generate new secure (random) key pair and provide the recovery phrase.

You can recover the same key later with from_phrase.

source

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

Generate key pair from given recovery phrase and password.

source

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

Make a new key pair from secret seed material.

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

source

pub fn from_seed_slice(seed_slice: &[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

source

pub 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

pub fn public(&self) -> Public

Get the public key.

source

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

Sign a message.

source

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

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

source

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

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

This doesn’t use the type system to ensure that sig and pubkey are the correct size. Use it only if you’re coming from byte buffers and need the speed.

type Public = Public

The type which is used to encode a public key.

type Seed = [u8 ; 32]

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 = DeriveError

Error returned from the derive function.

source

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
