}eth_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 signs arbitrary data (e.g. transaction) and uses the signature for impersonation.
NOTE: The address to sign with must be unlocked.
Parameters
account
20-byte DATA
Address
message
N-byte DATA
Message to sign
Return Value
DATA
Signature
