Network.Polkadot.Crypto

Polkadot signing types and methods.

classclass Pair a where

Class suitable for typical cryptographic PKI key pair type.

type family PublicKey a
The type which is used to encode a public key.
type family 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.

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.

Instances2Pair

classclass Verify a where

Means of signature verification.

verify :: (IdentifyAccount s, ByteArrayAccess ba) => a -> ba -> s -> Bool
Verify a message.

classclass Pair a => MultiPair a where

Multiple cryptographic type support.

multi_address :: a -> MultiAddress a
Derive universal account address.
multi_signer :: a -> MultiSigner a
Derive universal signer account identifier.
multi_sign :: ByteArrayAccess ba => a -> ba -> MultiSignature a
Sign message and derive universal signature.
