ERC-191 Signed Data Standard

Implementations§

Source§

impl Erc191

Source

pub fn recover( msg: impl AsRef<[u8]>, signature: &<Secp256k1 as Curve>::Signature, recovery_id: <Secp256k1 as RecoverableCurve>::RecoveryId, ) -> Option<<Secp256k1 as Curve>::PublicKey>

Try to recover public key which signed given message according to ERC-191 and produced given signature and recovery id.

Source

pub fn prehash(msg: impl AsRef<[u8]>) -> [u8; 32]

Derive prehash for signing according to following schema:

0x19 <0x45 (E)> <thereum Signed Message:\n" + len(message)> <data to sign>
