pub struct Pair { /* private fields */ }
Expand description
A key pair.
Implementations
sourceimpl Pair
impl Pair
sourcepub 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.
sourcepub fn sign_prehashed(&self, message: &[u8; 32]) -> Signature
pub fn sign_prehashed(&self, message: &[u8; 32]) -> Signature
Sign a pre-hashed message

sourcefn generate_with_phrase(password: Option<&str>) -> (Pair, String, [u8; 32])
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
.
sourcefn from_phrase(
phrase: &str,
password: Option<&str>
) -> Result<(Pair, [u8; 32]), SecretStringError>
fn from_phrase(
phrase: &str,
password: Option<&str>
) -> Result<(Pair, [u8; 32]), SecretStringError>
Generate key pair from given recovery phrase and password.
sourcefn from_seed(seed: &[u8; 32]) -> Pair
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
sourcefn 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
sourcefn derive<Iter: Iterator<Item = DeriveJunction>>(
&self,
path: Iter,
_seed: Option<[u8; 32]>
) -> Result<(Pair, Option<[u8; 32]>), DeriveError>
fn derive<Iter: Iterator<Item = DeriveJunction>>(
&self,
path: Iter,
_seed: Option<[u8; 32]>
) -> Result<(Pair, Option<[u8; 32]>), DeriveError>
Derive a child key from a series of given junctions.
sourcefn 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.
sourcefn verify_weak<P: AsRef<[u8]>, M: AsRef<[u8]>>(
sig: &[u8],
message: M,
pubkey: P
) -> bool
fn verify_weak<P: AsRef<[u8]>, M: AsRef<[u8]>>(
sig: &[u8],
message: M,
pubkey: P
) -> bool
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.
sourcefn 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 moresourcefn from_string(
