Polkadot signing types and methods.

Documentation

class Pair a where

Class suitable for typical cryptographic PKI key pair type.

Associated Types

type PublicKey a

The type which is used to encode a public key.

type Signature a

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.

Methods

generate :: IO a

Generate new secure (random) key pair.

from_seed :: ByteArrayAccess ba => ba -> Either String a

Generate new key pair from the provided seed.

from_phrase :: Text -> Maybe Text -> Either String a

Generate key pair from given recovery phrase and password.

public :: a -> PublicKey a

Get a public key.

sign :: ByteArrayAccess ba => a -> ba -> Signature a

Sign a message.
