Creates a signature from a private key, signs a message and ecrecover in Java. Hashes are equal to Solidity and recoverSigner works with values generated in Java in Solidity ECTools below. Uses web3j.
public class ECRecover {
private void pkDisplay() {
String privateKey1 = "c87509a1c067bbde78beb793e6fa76530b6382a4c0241e5e4a9ec0a0f44dc0d3";
Credentials credentials = Credentials.create(privateKey1);
System.out.println("pk:" + Numeric.toHexStringNoPrefix(credentials.getEcKeyPair().getPublicKey()));
String message = "now that's a text";
String label = "\u0019Ethereum Signed Message:\n"+ String.valueOf(message.getBytes().length) + message;
