Sign

post

The sign method calculates an Ethereum specific signature with: sign(keccak256("\x19Ethereum Signed Message:\n" + len(message) + message))).

By adding a prefix to the message makes the calculated signature recognisable 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.

Note: the address to sign with must be unlocked.

Parameters

  • DATA, 20 Bytes - address

  • DATA, N Bytes - message to sign

Returns

  • DATA: Signature
