Sign Message
The sign method calculates an Ethereum-specific signature. Adding a prefix to the message makes the calculated signature recognizable as an Ethereum-specific signature. This prevents misuse where a malicious dapp can sign arbitrary data (e.g. transaction) and use the signature to impersonate the victim.
