dart_wordlists

A library for passphrase word lists. Inspired by Diceware and others

Usage

generate pgp mnemonic from byte array

import 'package:dart_wordlists/dart_wordlists.dart';

main(List<String> arguments) async {
  PgpMnemonic pgpWords = new PgpMnemonic();
  await pgpWords.init();

  if (arguments.isEmpty) {
    print("You must supply a hex string (whitespace separation a-ok!)");
  } else {
    print(pgpWords.toPhraseFromHex(arguments.join(' ')).join(' '));
  }
}

running the example:

foo@bar$ pub run example/pgp_words.dart a2b4 ff5a 21a9
rebirth politeness Zulu existence blackjack passenger

foo@bar$ pub run example/pgp_unwords.dart rebirth politeness Zulu existence blackjack passenger
a2b4ff5a21a9

word list selection w/ collection sampler

A simple usage example:

import 'package:dart_wordlists/dart_wordlists.dart';
import 'package:dart_collection_sampler/dart_collection_sampler.dart';

import 'package:args/args.dart';


main(List<String> arguments) async {
  var argParser = new ArgParser()
    ..addOption("num", abbr: "n",
        help: "items to pick from rest of command line",
        defaultsTo: "6");

  var results = argParser.parse(arguments);

  sample(int.parse(results["num"]));
}

sample(int sampleSize) async {
  var loader = new WordlistLoader();

  var sampler = new CollectionSampler();

  var wordlists = [
    Wordlist.bip39_en,
    Wordlist.bip39_zh_CW,
    Wordlist.diceware_beale_en,
    Wordlist.eff_large_en
  ];
  for (final wl in wordlists) {
    var meta = loader.findMetadata(wl);
    print(loader.findMetadata(wl));

    var words = await loader.findLoader(wl).load();
    print(words);

    print ("sample: ${sampler.pickN(words, sampleSize)}");
    print ("\n");
  }
}
