ecdsa

Description:

ecdsa

Dart-ECDSA #
Package ecdsa implements the Elliptic Curve Digital Signature Algorithm, as defined in FIPS 186-3.
This implementation derives the nonce from dartlang random.Secure() temporarily.
The curves are all in elliptic package
Usage #
A simple usage example:
import 'package:ecdsa/ecdsa.dart';
import 'package:elliptic/elliptic.dart';

void main() {
var ec = getP256();
var priv = ec.generatePrivateKey();
var pub = priv.publicKey;
print(priv);
print(pub);
var hashHex =
'b94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9';
var hash = List<int>.generate(hashHex.length ~/ 2,
(i) => int.parse(hashHex.substring(i * 2, i * 2 + 2), radix: 16));
var sig = signature(priv, hash);

var result = verify(pub, hash, sig);
assert(result);
}
