The sign method calculates an Ethereum specific signature withsign(keccak256(\x19Ethereum Signed Message\n + len(message) +message))).By adding a prefix to the message makes the calculated signaturerecognisable as an Ethereum specific signature. This prevents misusewhere a malicious DApp can sign arbitrary data (e.g. transaction) anduse the signature to impersonate the victim.Note the address to sign with must be unlocked.

Parameters

DATA - string

address.

DATA - string

message to sign.
