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

👎Deprecated: please use verify instead

Verify a signature on a message. Returns true if the signature is good. Parses Signature using parse_overflowing_slice.
