source§const CRYPTO_ID: CryptoTypeId = super::CRYPTO_ID
const CRYPTO_ID: CryptoTypeId = super::CRYPTO_ID
Identifier of the crypto type of this application-specific key type.

§type Seed = <Pair as Pair>::Seed
type Seed = <Pair as Pair>::Seed
The type used to (minimally) encode the data required to securely create
a new key pair.
§type Signature = Signature
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 generate_with_phrase(password: Option<&str>) -> (Self, String, Self::Seed)
fn generate_with_phrase(password: Option<&str>) -> (Self, String, Self::Seed)
Generate new secure (random) key pair and provide the recovery phrase. Read more

phrase: &str,
password: Option<&str>
) -> Result<(Self, Self::Seed), SecretStringError>
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 derive<Iter: Iterator<Item = DeriveJunction>>(
&self,
path: Iter,
seed: Option<Self::Seed>
) -> Result<(Self, Option<Self::Seed>), DeriveError>
fn derive<Iter: Iterator<Item = DeriveJunction>>( &self, path: Iter, seed: Option<Self::Seed> ) -> Result<(Self, Option<Self::Seed>), DeriveError>
Derive a child key from a series of given junctions.
source§fn from_seed(seed: &Self::Seed) -> Self
fn from_seed(seed: &Self::Seed) -> Self
Generate new key pair from the provided
seed
. Read moresource§fn from_seed_slice(seed: &[u8]) -> Result<Self, SecretStringError>
fn from_seed_slice(seed: &[u8]) -> Result<Self, SecretStringError>
Make a new key pair from secret seed material. The slice must be the correct size or
an error will be returned. Read more
source§fn verify<M: AsRef<[u8]>>(
sig: &Self::Signature,
message: M,
pubkey: &Self::Public
) -> bool
fn verify<M: AsRef<[u8]>>( sig: &Self::Signature, message: M, pubkey: &Self::Public ) -> bool
Verify a signature on a message. Returns true if the signature is good.
source§fn from_string_with_seed(
s: &str,
password_override: Option<&str>
) -> Result<(Self, Option<Self::Seed>), SecretStringError>
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 moresource§fn from_string(
s: &str,
password_override: Option<&str>
) -> Result<Self, SecretStringError>
fn from_string( s: &str, password_override: Option<&str> ) -> Result<Self, SecretStringError>
Interprets the string
s
in order to generate a key pair. Read moreAuto Trait Implementations§
