}klay_sign
The sign method calculates a Klaytn-specific signature with:
sign(keccak256("\x19Klaytn Signed Message:\n" + len(message) + message)))Adding a prefix to the message makes the calculated signature recognizable as a Klaytn-specific signature. This prevents misuse where a malicious dApp can sign arbitrary data, e.g., transaction, and use the signature to impersonate the victim.
NOTE: The address to sign with must be unlocked.
Parameters
account

Address
message
N-byte DATA
Message to sign
Return Value
