void main(){
  KeyPair kp = Signature.keyPair();
  print("secretKey: \"${TweetNaclFast.hexEncodeToString(kp.secretKey)}\"");
  print("publicKey: \"${TweetNaclFast.hexEncodeToString(kp.publicKey)}\"");

  Uint8List bytes = utf8.encode("test string");
  
  Signature s1 = Signature(null, kp.secretKey);
