FormatException: Bad UTF-8 encoding about crypton HOT 5 CLOSED

The reason for your problem is, that the result of createSHA256Signature is not a UTF-8 encoded string.

Here is your code bit working.

import 'dart:convert';
import 'package:crypton/crypton.dart';

void main() {
  var rsaKeypair = RSAKeypair.fromRandom();
  var message = 'test message';
  var signature = rsaKeypair.privateKey.createSHA256Signature(utf8.encode(message));
  var signatureStr = base64Encode(signature);
  var verified = rsaKeypair.publicKey.verifySHA256Signature(utf8.encode(message), base64Decode(signatureStr));
  print(verified);
}

from crypton.

Let me take a look

from crypton.

I'll upload a fixed version of the deprecated RSA function createSignature and verifySignature to pub.dev

Does that resolve your issue?
