Usage #
import 'dart:typed_data';

import 'package:argon2/argon2.dart';

void main() {
var password = 'pass123456';
var salt = 'somesalt'.toBytesLatin1();

var parameters = Argon2Parameters(
Argon2Parameters.ARGON2_i,
salt,
version: Argon2Parameters.ARGON2_VERSION_10,
iterations: 2,
memoryPowerOf2: 16,
);

print('Parameters: $parameters');

var argon2 = Argon2BytesGenerator();

argon2.init(parameters);

var passwordBytes = parameters.converter.convert(password);

print('Generating key from password...');

var result = Uint8List(32);
argon2.generateBytes(passwordBytes, result, 0, result.length);

var resultHex = result.toHexString();

print('Result: $resultHex');
}
