Functions

func PrefixedHash

func PrefixedHash(data []byte) []byte

PrefixedHash is a helper function that calculates a hash for the given message that can be safely used to calculate a signature from.

The hash is calculated as

keccak256("\x19Ethereum Signed Message:\n"${message length}${message}).

This gives context to the signed message and prevents signing of transactions.
