eth_sign: Ethereum specific signature

In gethr: Access to Ethereum-Based Blockchains Through Geth Nodes

Description

eth_sign returns an Ethereum specific signature with Keccak256.

Usage

eth_sign(address, message)

Arguments

address	Address - Address of the user.
message	String - Message to sign.

Details

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.

Value

Data - Signature.
