bool - true if verify successfully, else return error
Example
// sign a string message
var str = "helloworld";
// convert to hex format and remove the beginning "0x"
var hexStrWithout0x = tronWeb.toHex(str).replace(/^0x/, '');
// conert hex string to byte array
var byteArray = tronWeb.utils.code.hexStr2byteArray(hexStrWithout0x)
// keccak256 computing, then remove "0x"
var strHash= tronWeb.sha3(byteArray).replace(/^0x/, '');
// sign
var signedStr = await tronWeb.trx.sign(strHash).replace(/^0x/, '');
var tail = signedStr.substring(128, 130);
if(tail == '01')
{
signedStr = signedStr.substring(0,128)+'1c';
}
else if(tail == '00')
{
signedStr = signedStr.substring(0,128)+'1b';
}
// verify the signature
var res = await tronWeb.trx.verifyMessage(strHash,signedStr,'TPNcZ1j55FrGpsaw6K6rVjuL4HfT8ZbBf7')
console.log(res);
