Error Handling

This method throws an exception on failure. Use try-catch:

try {
  const { address, pubkey, sig, message } = await Turing.signMessage({
    message: "hello world",
    encoding: "base64",
  });
  console.log("Signed by:", address);
  console.log("Signature:", sig);
} catch (error) {
  console.error("Signing failed:", error);
}

Verify Signature

You can verify the signature using tbc-lib-js:

import * as tbc from "tbc-lib-js";

const msg_buf = Buffer.from(message, encoding);
const isValid = tbc.Message.verify(msg_buf, address, sig);
console.log("Signature valid:", isValid);
