dart_wordlists #

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

Created from templates made available by Stagehand under a BSD-style license.

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.length == 0) {
    print("You must supply a hex string (whitespace separation a-ok!)");
  } else {
    print(pgpWords.toPhraseFromHex(arguments.join(' ')).join(' '));

running the example:

$ pub run example/pgp_words.dart a2b4 ff5a 21a9

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 sampleSize) async {
      var loader = new WordlistLoader();
      var sampler = new CollectionSampler();
      var wordlists = [
      for (var wl in wordlists) {
        var meta = loader.findMetadata(wl);
        var words = await loader.findLoader(wl).load();
        print ("sample: ${sampler.pickN(words, sampleSize)}");
        print ("\n");
