Implementations§
§impl Pair
impl Pair
pub fn from_legacy_string(s: &str, password_override: Option<&str>) -> Pair
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.
pub fn sign_prehashed(
&self,
message: &[u8; 32],
) -> CryptoBytes<sp_core::::ecdsa::Signature::{constant#0}, (SignatureTag, EcdsaTag)>
pub fn sign_prehashed( &self, message: &[u8; 32], ) -> CryptoBytes<sp_core::::ecdsa::Signature::{constant#0}, (SignatureTag, EcdsaTag)>
Sign a pre-hashed message
pub fn verify_prehashed(
sig: &CryptoBytes<sp_core::::ecdsa::Signature::{constant#0}, (SignatureTag, EcdsaTag)>,
message: &[u8; 32],
public: &CryptoBytes<sp_core::::ecdsa::Public::{constant#0}, (PublicTag, EcdsaTag)>,
) -> bool
pub fn verify_prehashed( sig: &CryptoBytes<sp_core::::ecdsa::Signature::{constant#0}, (SignatureTag, EcdsaTag)>, message: &[u8; 32], public: &CryptoBytes<sp_core::::ecdsa::Public::{constant#0}, (PublicTag, EcdsaTag)>, ) -> bool
Verify a signature on a pre-hashed message. Return true
if the signature is valid
and thus matches the given public
key.
pub fn verify_deprecated<M>(
sig: &CryptoBytes<sp_core::::ecdsa::Signature::{constant#0}, (SignatureTag, EcdsaTag)>,
message: M,
pubkey: &CryptoBytes<sp_core::::ecdsa::Public::{constant#0}, (PublicTag, EcdsaTag)>,
) -> bool
👎Deprecated: please use verify
instead
pub fn verify_deprecated<M>( sig: &CryptoBytes<sp_core::::ecdsa::Signature::{constant#0}, (SignatureTag, EcdsaTag)>, message: M, pubkey: &CryptoBytes<sp_core::::ecdsa::Public::{constant#0}, (PublicTag, EcdsaTag)>, ) -> bool
verify
insteadVerify a signature on a message. Returns true if the signature is good. Parses Signature using parse_overflowing_slice.

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

&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.
§fn public(
&self,
) -> CryptoBytes<sp_core::::ecdsa::Public::{constant#0}, (PublicTag, EcdsaTag)>
fn public( &self, ) -> CryptoBytes<sp_core::::ecdsa::Public::{constant#0}, (PublicTag, EcdsaTag)>
Get the public key.
§fn sign(
&self,
message: &[u8],
) -> CryptoBytes<sp_core::::ecdsa::Signature::{constant#0}, (SignatureTag, EcdsaTag)>
fn sign( &self, message: &[u8], ) -> CryptoBytes<sp_core::::ecdsa::Signature::{constant#0}, (SignatureTag, EcdsaTag)>
Sign a message.
§fn verify<M>(
sig: &CryptoBytes<sp_core::::ecdsa::Signature::{constant#0}, (SignatureTag, EcdsaTag)>,
message: M,
public: &CryptoBytes<sp_core::::ecdsa::Public::{constant#0}, (PublicTag, EcdsaTag)>,
) -> bool
fn verify<M>( sig: &CryptoBytes<sp_core::::ecdsa::Signature::{constant#0}, (SignatureTag, EcdsaTag)>, message: M, public: &CryptoBytes<sp_core::::ecdsa::Public::{constant#0}, (PublicTag, EcdsaTag)>, ) -> bool
Verify a signature on a message. Returns true if the signature is good.
§fn to_raw_vec(&self) -> Vec<u8> ⓘ
fn to_raw_vec(&self) -> Vec<u8> ⓘ
Return a vec filled with raw data.

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 moreAuto Trait Implementations§
